text: In the 30% to 60% of cases classified as "hyperadrenergic POTS", norepinephrine levels are elevated on standing, often due to hypovolemia or partial autonomic neuropathy. A smaller minority of people with POTS have (typically very high) standing norepinephrine levels that are elevated even in the absence of hypovolemia and autonomic neuropathy; this is classified as "central hyperadrenergic POTS". The high norepinephrine levels contribute to symptoms of tachycardia. Another subtype, "neuropathic POTS", is associated with denervation of sympathetic nerves in the lower limbs. In this subtype, it is thought that impaired constriction of the blood vessels causes blood to pool in the veins of the lower limbs. Heart rate increases to compensate for this blood pooling.


title: Postural orthostatic tachycardia syndrome

text: In up to 50% of cases, there was an onset of symptoms following a viral illness. It may also be linked to vaccination, physical trauma, concussion, pregnancy, or surgery. It is believed that these events could act as a trigger for an autoimmune response that result in POTS.


text: POTS is more common in females than males. It has also been shown to be linked in patients with acute stressors such as pregnancy, recent surgery, or recent trauma. POTS also has been linked to patients with a history of autoimmune diseases, irritable bowel syndrome, anemia, hyperthyroidism, fibromyalgia, diabetes, amyloidosis, sarcoidosis, systemic lupus erythematosus, and cancer. Genetics likely plays a role, with one study finding that one in eight POTS patients reported a history of orthostatic intolerance in their family.


text: There is an increasing number of studies indicating that POTS is an autoimmune disease. A high number of patients has elevated levels of autoantibodies against the adrenergic alpha 1 receptor and against the muscarinic acetylcholine M4 receptor.


text: Elevations of autoantibodies targeting adrenergic α1 receptor has been associated with symptoms severity in patients with POTS.


text: More recently, autoantibodies against other targets have been identified in small cohorts of POTS patients. Signs of innate immune system activation with elaboration of pro-inflammatory cytokines has also been reported in a cohort of POTS patients.


text: If POTS is caused by another condition, it may be classified as "secondary POTS". Chronic diabetes mellitus is one common cause. POTS can also be secondary to gastrointestinal disorders that are associated with low fluid intake due to nausea or fluid loss through diarrhea, leading to hypovolemia. Systemic lupus erythematosus and other autoimmune diseases have also been linked to POTS.


text: There is a subset of patients who present with both POTS and mast cell activation syndrome (MCAS), and it is not yet clear whether MCAS is a secondary cause of POTS or simply comorbid, however, treating MCAS for these patients can significantly improve POTS symptoms.


text: POTS can also co-occur in all types of Ehlers–Danlos syndrome (EDS), a hereditary connective tissue disorder marked by loose hypermobile joints prone to subluxations and dislocations, skin that exhibits moderate or greater laxity, easy bruising, and many other symptoms. A trifecta of POTS, EDS, and Mast Cell Activation Syndrome (MCAS) is becoming increasingly more common, with a genetic marker common among all three conditions. POTS is also often accompanied by vasovagal syncope, with a 25% overlap being reported. There are some overlaps between POTS and chronic fatigue syndrome, with evidence of POTS in 10–20% of CFS cases. Fatigue and reduced exercise tolerance are prominent symptoms of both conditions, and dysautonomia may underlie both conditions.


text: There are case reports of people developing POTS and other forms of dysautonomia post-COVID. There is no good large-scale empirical evidence yet to prove a connection, so for now the evidence is preliminary.


text: POTS is most commonly diagnosed by a cardiologist (41%), cardiac electrophysiologist (15%), or neurologist (19%). The average number of physicians seen before receiving diagnosis is seven, and the average delay before diagnosis is 4.7 years.


text: An increase in heart rate upon moving to an upright posture is known as orthostatic (upright) tachycardia (fast heart rate). It occurs without any coinciding drop in blood pressure, as that would indicate orthostatic hypotension. Certain medications to treat POTS may cause orthostatic hypotension. It is accompanied by other features of orthostatic intolerance—symptoms that develop in an upright position and are relieved by reclining. These orthostatic symptoms include palpitations, light-headedness, chest discomfort, shortness of breath, nausea, weakness or "heaviness" in the lower legs, blurred vision, and cognitive difficulties.


text: A variety of autonomic tests are employed to exclude autonomic disorders that could underlie symptoms, while endocrine testing is used to exclude hyperthyroidism and rarer endocrine conditions. Electrocardiography is normally performed on all patients to exclude other possible causes of tachycardia. In cases where a particular associated condition or complicating factor are suspected, other non-autonomic tests may be used: echocardiography to exclude mitral valve prolapse, and thermal threshold tests for small-fiber neuropathy.


text: Testing the cardiovascular response to prolonged head-up tilting, exercise, eating, and heat stress may help determine the best strategy for managing symptoms. POTS has also been divided into several types (see § Causes), which may benefit from distinct treatments. People with neuropathic POTS show a loss of sweating in the feet during sweat tests, as well as impaired norepinephrine release in the leg, but not arm. This is believed to reflect peripheral sympathetic denervation in the lower limbs. People with hyperadrenergic POTS show a marked increase of blood pressure and norepinephrine levels when standing, and are more likely to have from prominent palpitations, anxiety, and tachycardia.


text: People with POTS can be misdiagnosed with inappropriate sinus tachycardia (IST) as they present similarly. One distinguishing feature is those with POTS rarely exhibit >100 bpm while in a supine position, while patients with IST often have a resting heart rate >100 bpm. Additionally patients with POTS display a more pronounced change in heart rate in response to postural change.


text: POTS treatment involves using multiple methods in combination to counteract cardiovascular dysfunction, address symptoms, and simultaneously address any associated disorders. For most patients, water intake should be increased, especially after waking, in order to expand blood volume (reducing hypovolemia). Eight to ten cups of water daily are recommended. Increasing salt intake, by adding salt to food, taking salt tablets, or drinking sports drinks and other electrolyte solutions is an effective way to raise blood pressure by helping the body retain water. Different physicians recommend different amounts of sodium to their patients. Combining these techniques with gradual physical training enhances their effect. In some cases, when increasing oral fluids and salt intake is not enough, intravenous saline or the drug desmopressin is used to help increase fluid retention.


text: Large meals worsen symptoms for some people. These people may benefit from eating small meals frequently throughout the day instead. Alcohol and food high in carbohydrates can also exacerbate symptoms of orthostatic hypotension. Excessive consumption of caffeine beverages should be avoided, because they can promote urine production (leading to fluid loss) and consequently hypovolemia. Exposure to extreme heat may also aggravate symptoms.


text: Prolonged physical inactivity can worsen the symptoms of POTS. Techniques that increase a person's capacity for exercise, such as endurance training or graded exercise therapy, can relieve symptoms for some patients. Aerobic exercise performed for 20 minutes a day, three times a week, is sometimes recommended for patients who can tolerate it. Exercise may have the immediate effect of worsening tachycardia, especially after a meal or on a hot day. In these cases, it may be easier to exercise in a semi-reclined position, such as riding a recumbent bicycle, rowing, or swimming.


text: When changing to an upright posture, finishing a meal, or concluding exercise, a sustained hand grip can briefly raise the blood pressure, possibly reducing symptoms. Compression garments can also be of benefit by constricting blood pressures with external body pressure.


text: Aggravating factors include exertion (81%), continued standing (80%), heat (79%), and after meals (42%).


text: If nonpharmacological methods are ineffective, medication may be necessary. Medications used may include beta blockers, pyridostigmine, midodrine, or fludrocortisone. As of 2013, no medication has been approved by the U.S. Food and Drug Administration to treat POTS, but a variety are used off-label. Their efficacy has not yet been examined in long-term randomized controlled trials.


text: Fludrocortisone may be used to enhance sodium retention and blood volume, which may be beneficial not only by augmenting sympathetically mediated vasoconstriction, but also because a large subset of POTS patients appear to have low absolute blood volume.


text: While people with POTS typically have normal or even elevated arterial blood pressure, the neuropathic form of POTS is presumed to constitute a selective sympathetic venous denervation. In these patients the selective Alpha-1 adrenergic receptor agonist midodrine may increase venous return, enhance stroke volume, and improve symptoms. Midodrine should only be taken during the daylight hours as it may promote supine hypertension.


text: Sinus node blocker Ivabradine can successfully restrain heart rate in POTS without affecting blood pressure, demonstrated in approximately 60% of people with POTS treated in an open-label trial of ivabradine experienced symptom improvement.


text: Pyridostigmine has been reported to restrain heart rate and improve chronic symptoms in approximately half of people.


text: The selective alpha-1 agonist phenylephrine has been used successfully to enhance venous return and stroke volume in some people with POTS. However, this medication may be hampered by poor oral bioavailability.


text: POTS has a favorable prognosis when managed appropriately. Symptoms improve within five years of diagnosis for many patients, and 60% return to their original level of functioning. Approximately 90% of people with POTS respond to a combination of pharmacological and physical treatments. Those who develop POTS in their early to mid teens will likely respond well to a combination of physical methods as well as pharmacotherapy. Outcomes are more guarded for adults newly diagnosed with POTS. Some people do not recover, and a few even worsen with time. The hyperadrenergic type of POTS typically requires continuous therapy. If POTS is caused by another condition, outcomes depend on the prognosis of the underlying disorder.


text: The prevalence of POTS is unknown. One study estimated a minimal rate of 170 POTS cases per 100,000 individuals, but the true prevalence is likely higher due to underdiagnosis. Another study estimated that there are at least 500,000 cases in the United States. POTS is more common in women than men, with a female-to-male ratio of 4:1. Most people with POTS are aged between 20 and 40, with an average onset of 21. Diagnoses of POTS beyond age 40 are rare, perhaps because symptoms improve with age.


text: In 1871, physician Jacob Mendes Da Costa described a condition that resembled the modern concept of POTS. He named it "irritable heart syndrome". Cardiologist Thomas Lewis expanded on the description, coining the term "soldier's heart" because it was often found among military personnel. The condition came to be known as Da Costa's syndrome, which is now recognized as several distinct disorders, including POTS.


text: "Postural tachycardia syndrome" was coined in 1982 in a description of a patient who had postural tachycardia, but not orthostatic hypotension. Ronald Schondorf and Phillip A. Low of the Mayo Clinic first used the name "postural orthostatic tachycardia syndrome", POTS, in 1993.


text: British politician Nicola Blackwood revealed in March 2015 that she had been diagnosed with Ehlers–Danlos syndrome in 2013 and that she had later been diagnosed with POTS. She was appointed Parliamentary Under-Secretary of State for Life Science by Prime Minister Theresa May in 2019 and given a life peerage that enabled her to take a seat in Parliament. As a junior minister, it is her responsibility to answer questions in parliament on the subjects of Health and departmental business. When answering these questions, it is customary for ministers to sit when listening to the question and then to rise to give an answer from the despatch box, thus standing up and sitting down numerous times in quick succession throughout a series of questions. On 17 June 2019, she fainted during one of these questioning sessions after standing up from a sitting position four times in the space of twelve minutes, and it was suggested that her POTS was a factor in her fainting. Asked about the incident, she stated: "I was frustrated and embarrassed my body gave up on me at work ... But I am grateful it gives me a chance to shine a light on a condition many others are also living with."


title: India–Pakistan relations

text: India–Pakistan relations refer to the bilateral ties between the Republic of India and the Islamic Republic of Pakistan. The two countries have a complex and largely hostile relationship that is rooted in a multitude of historical and political events, most notably the partition of British India in August 1947; the India–Pakistan border is one of the most militarised international boundaries in the world. Northern India and most of modern-day Pakistan overlap with each other in terms of their common Indo-Aryan demographic, natively speaking a variety of Indo-Aryan languages (mainly Punjabi, Sindhi, and Hindi–Urdu).


title: India–Pakistan relations

text: Two years after World War II, the United Kingdom formally dissolved British India, dividing it into two new sovereign nations: the Dominion of India and the Dominion of Pakistan. The partitioning of the former British colony resulted in the displacement of up to 15 million people, with the death toll estimated to have reached between several hundred thousand and one million people as scores of Hindus and Muslims migrated in opposite directions across the Radcliffe Line to reach India and Pakistan, respectively. In 1950, India emerged as a secular republic with a Hindu-majority population and a large Muslim minority. Shortly afterwards, in 1956, Pakistan emerged as an Islamic republic with a Muslim-majority population and a large Hindu minority; it later lost most of its Hindu population following its defeat in the Bangladesh Liberation War of 1971, which saw the secession of East Pakistan as the independent country of Bangladesh.


title: India–Pakistan relations

text: While both countries established full diplomatic ties shortly after their formal independence, their relationship was quickly overshadowed by the mutual effects of the partition as well as by the emergence of conflicting territorial claims over various princely states, with the most significant dispute being that of Jammu and Kashmir. Since 1947, India and Pakistan have fought three major wars and one undeclared war, and have also engaged in numerous armed skirmishes and military standoffs; the Kashmir conflict has served as the catalyst for every war between the two states, with the exception of the Indo-Pakistani War of 1971, which instead occurred alongside the Bangladesh Liberation War.


title: India–Pakistan relations

text: There have been numerous attempts to improve the relationship, notably the Shimla summit, the Agra summit, and the Lahore summit, as well as various peace and co-operation initiatives. Despite those efforts, relations between the countries have remained frigid, following repeated acts of cross-border terrorism. According to a BBC World Service poll in 2017, only 5% of Indians view Pakistan's influence positively, with 85% expressing a negative view, while 11% of Pakistanis view India's influence positively, with 62% expressing a negative view.


title: India–Pakistan relations

text: Massive population exchanges occurred between the two newly formed states in the months immediately following the partition. There was no conception that population transfers would be necessary because of the partitioning. Religious minorities were expected to stay put in the states they found themselves residing in. However, while an exception was made for Punjab, where the transfer of populations was organised because of the communal violence affecting the province, this did not apply to other provinces.


title: India–Pakistan relations

text: The partition of British India split the former British province of Punjab and Bengal between the Dominion of India and the Dominion of Pakistan. The mostly Muslim western part of the province became Pakistan's Punjab province; the mostly Hindu and Sikh eastern part became India's East Punjab state (later divided into the new states of Punjab, Haryana and Himachal Pradesh). Many Hindus and Sikhs lived in the west, and many Muslims lived in the east, and the fears of all such minorities were so great that the Partition saw many people displaced and much inter-communal violence. Some have described the violence in Punjab as a retributive genocide. Total migration across Punjab during the partition is estimated at around 12 million people; around 6.5 million Muslims moved from East Punjab to West Punjab, and 4.7 million Hindus and Sikhs moved from West Punjab to East Punjab.


title: India–Pakistan relations

text: According to the British plan for the partition of British India, all the 680 princely states were allowed to decide which of the two countries to join. With the exception of a few, most of the Muslim-majority princely-states acceded to Pakistan while most of the Hindu-majority princely states joined India. However, the decisions of some of the princely states would shape the Pakistan-India relationship considerably in the years to come.


title: India–Pakistan relations

text: Junagadh was a state on the south-western end of Gujarat, with the principalities of Manavadar, Mangrol and Babriawad. It was not contiguous to Pakistan and other states physically separated it from Pakistan. The state had an overwhelming Hindu population which constituted more than 80% of its citizens, while its ruler, Nawab Mahabat Khan, was a Muslim. Mahabat Khan acceded to Pakistan on 15 August 1947. Pakistan confirmed the acceptance of the accession on 15 September 1947.


title: India–Pakistan relations

text: India did not accept the accession as legitimate. The Indian point of view was that Junagadh was not contiguous to Pakistan, that the Hindu majority of Junagadh wanted it to be a part of India, and that the state was surrounded by Indian territory on three sides.


title: India–Pakistan relations

text: The Pakistani point of view was that since Junagadh had a ruler and governing body who chose to accede to Pakistan, it should be allowed to do so. Also, because Junagadh had a coastline, it could have maintained maritime links with Pakistan even as an enclave within India.


title: India–Pakistan relations

text: Neither of the states was able to resolve this issue amicably and it only added fuel to an already charged environment. Sardar Patel, India's Home Minister, felt that if Junagadh was permitted to go to Pakistan, it would create communal unrest across Gujarat. The government of India gave Pakistan time to void the accession and hold a plebiscite in Junagadh to pre-empt any violence in Gujarat. Samaldas Gandhi formed a government-in-exile, the "Arzi Hukumat" (in Urdu: "Arzi": Transitional, "Hukumat": Government) of the people of Junagadh. Patel ordered the annexation of Junagadh's three principalities.


title: India–Pakistan relations

text: India cut off supplies of fuel and coal to Junagadh, severed air and postal links, sent troops to the frontier, and occupied the principalities of Mangrol and Babariawad that had acceded to India. On 26 October, Nawab of Junagadh and his family fled to Pakistan following clashes with Indian troops. On 7 November, Junagadh's court, facing collapse, invited the Government of India to take over the State's administration. The Dewan of Junagadh, Sir Shah Nawaz Bhutto, the father of the more famous Zulfiqar Ali Bhutto, decided to invite the Government of India to intervene and wrote a letter to Mr. Buch, the Regional Commissioner of Saurashtra in the Government of India to this effect. The Government of Pakistan protested. The Government of India rejected the protests of Pakistan and accepted the invitation of the Dewan to intervene. Indian troops occupied Junagadh on 9 November 1947. In February 1948, a plebiscite held almost unanimously voted for accession to India.


title: India–Pakistan relations

text: Kashmir was a Muslim-majority princely state, ruled by a Hindu king, Maharaja Hari Singh. At the time of the partition of India, Maharaja Hari Singh, the ruler of the state, preferred to remain independent and did not want to join either the Dominion of India or the Dominion of Pakistan.


title: India–Pakistan relations

text: Despite the standstill agreement with Pakistan, teams of Pakistani forces were dispatched into Kashmir. Backed by Pakistani paramilitary forces, Pashtun Mehsud tribals invaded Kashmir in October 1947 under the code name "Operation Gulmarg" to seize Kashmir. The Maharaja requested military assistance from India. The Governor General of India, Lord Mountbatten, required the Maharaja to accede to India before India could send troops. Accordingly, the instrument of accession was signed and acceped during 26–27 October 1947. The accession as well as India's military assistance were supported by Sheikh Abdullah, the state's political leader heading the National Conference party, and Abdullah was appointed as the Head of Emergency Administration of the state the following week.


title: India–Pakistan relations

text: Pakistan refused to accept the state's accession to India and escalated the conflict, by giving full-fledged support to the rebels and invading tribes. A constant replenishment of Pashtun tribes were organised, and provided arms and ammunition as well as military leadership.


title: India–Pakistan relations

text: Indian troops managed to evict the invading tribes from the Kashmir Valley but the onset of winter made much of the state impassable. In December 1947, India referred the conflict to the United Nations Security Council, requesting it to prevent the outbreak of a general war between the two fledgling nations. The Security Council passed Resolution 47, asking Pakistan to withdraw all its nationals from Kashmir, asking India to withdraw the bulk of its forces as a second step, and offering to conduct a plebiscite to determine the people's wishes. Though India rejected the resolution, it accepted a suitably amended version of it negotiated by the UN Commission set up for the purpose, as did Pakistan towards the end of 1948. A ceasefire was declared on the 1 January the following year.


title: India–Pakistan relations

text: However, India and Pakistan could not agree on the suitable steps for demilitarisation to occur as prelude to the plebiscite. Pakistan organised the rebel fighting forces of Azad Kashmir into a full-fledged military of 32 battalions, and India insisted that it should be disbanded as part of the demilitarisation. No agreement was reached and the plebiscite never took place.


title: India–Pakistan relations

text: India and Pakistan have fought in numerous armed conflicts since their independence. There are three major wars that have taken place between the two states, namely in 1947, 1965 and the Bangladesh Liberation War in 1971. In addition to this was the unofficial Kargil War in 1999 and some border skirmishes. Major conflicts between India and Pakistan, War of1947 and War of 1965, and a small-scale Kargil War in 1999, were triggered by conflict over the border of Kashmir. While both nations have held a shaky cease-fire agreement since 2003, they continue to trade fire across the disputed area. Both nations blame the other for breaking the cease-fire agreement, claiming that they are firing in retaliation for attacks. On both sides of the disputed border, an increase in territorial skirmishes that started in late 2016 and escalated into 2018 killed hundreds of civilians and made thousand homeless.


title: India–Pakistan relations

text: The Indo-Pakistani War of 1965 started following the culmination of skirmishes that took place between April 1965 and September 1965 and Pakistan's Operation Gibraltar, which was designed to infiltrate forces into Jammu and Kashmir to precipitate an insurgency against rule by India. India retaliated by launching a full-scale military attack on West Pakistan. The seventeen-day war caused thousands of casualties on both sides and witnessed the largest engagement of armored vehicles and the largest tank battle since World War II. Hostilities between the two countries ended after a United Nations-mandated ceasefire was declared following diplomatic intervention by the Soviet Union and the United States, and the subsequent issuance of the Tashkent Declaration. The five-week war caused thousands of casualties on both sides. Most of the battles were fought by opposing infantry and armoured units, with substantial backing from air forces, and naval operations. It ended in a United Nations (UN) mandated ceasefire and the subsequent issuance of the Tashkent Declaration.


title: India–Pakistan relations

text: Pakistan, since independence, was geo-politically divided into two major regions, West Pakistan and East Pakistan. East Pakistan was occupied mostly by Bengali people. After a Pakistani military operation and a genocide on Bengalis in December 1971, following a political crisis in East Pakistan, the situation soon spiralled out of control in East Pakistan and India intervened in favour of the rebelling Bengali populace. The conflict, a brief but bloody war, resulted in the independence of East Pakistan. In the war, the Indian Army invaded East Pakistan from three sides, while the Indian Navy used the aircraft carrier to impose a naval blockade of East Pakistan. The war saw the first offensive operations undertaken by the Indian Navy against an enemy port, when Karachi harbour was attacked twice during Operation Trident (1971) and Operation Python. These attacks destroyed a significant portion of Pakistan's naval strength, whereas no Indian ship was lost. The Indian Navy did, however, lose a single ship, when INS Khukri (F149) was torpedoed by a Pakistani submarine. 13 days after the invasion of East Pakistan, 93,000 Pakistani military personnel surrendered to the Indian Army and the Mukti Bahini. After the surrender of Pakistani forces, East Pakistan became the independent nation of Bangladesh.


title: India–Pakistan relations

text: During the winter months of 1998–99, the Indian army vacated its posts at very high peaks in Kargil sector in Kashmir as it used to do every year. Pakistani Army intruded across the Line of Control and occupied the posts. Indian army discovered this in May 1999 when the snow thawed. This resulted in intense fighting between Indian and Pakistani forces, known as the Kargil conflict. Backed by the Indian Air Force, the Indian Army regained many of the posts that Pakistan had occupied. Pakistan later withdrew from the remaining portion under international pressure and high casualties.


title: India–Pakistan relations

text: The Indus Waters Treaty governs the rivers that flow from India into Pakistan. Water is cited as one possible cause for a conflict between the two nations, but to date issues such as the Nimoo Bazgo Project have been resolved through diplomacy.


title: India–Pakistan relations

text: In 1949, India recorded close to 1 million Hindu refugees, who flooded into West Bengal and other states from East Pakistan (now Bangladesh), owing to communal violence, intimidation and repression from authorities. The plight of the refugees outraged Hindus and Indian nationalists, and the refugee population drained the resources of Indian states, which were unable to absorb them. While not ruling out war, Prime Minister Nehru and Sardar Patel invited Liaquat Ali Khan for talks in Delhi. Although many Indians termed this appeasement, Nehru signed a pact with Liaquat Ali Khan that pledged both nations to the protection of minorities and creation of minority commissions. Khan and Nehru also signed a trade agreement, and committed to resolving bilateral conflicts through peaceful means. Steadily, hundreds of thousands of Hindus returned to East Pakistan, but the thaw in relations did not last long, primarily owing to the Kashmir conflict.


title: India–Pakistan relations

text: According to some reports published by the Council of Foreign Relations, the Pakistan military and the ISI have provided covert support to terrorist groups active in Kashmir, including the al-Qaeda affiliate Jaish-e-Mohammed. Pakistan has denied any involvement in terrorist activities in Kashmir, arguing that it only provides political and moral support to the secessionist groups who wish to escape Indian rule. Many Kashmiri militant groups also maintain their headquarters in Pakistan-administered Kashmir, which is cited as further proof by the Indian government.


title: India–Pakistan relations

text: Journalist Stephen Suleyman Schwartz notes that several militant and criminal groups are "backed by senior officers in the Pakistani army, the country's ISI intelligence establishment and other armed bodies of the state."


title: India–Pakistan relations

text: The attack on the Indian Parliament was by far the most dramatic attack carried out allegedly by Pakistani terrorists. India blamed Pakistan for carrying out the attacks, an allegation which Pakistan strongly denied. The following 2001–2002 India–Pakistan standoff raised concerns of a possible nuclear confrontation. However, international peace efforts ensured the cooling of tensions between the two nuclear-capable nations.


title: India–Pakistan relations

text: Apart from this, the most notable was the hijacking of Indian Airlines Flight IC 814 en route New Delhi from Kathmandu, Nepal. The plane was hijacked on 24 December 1999 approximately one hour after takeoff and was taken to Amritsar airport and then to Lahore in Pakistan. After refuelling the plane took off for Dubai and then finally landed in Kandahar, Afghanistan. Under intense media pressure, New Delhi complied with the hijackers' demand and freed Maulana Masood Azhar from its captivity in return for the freedom of the Indian passengers on the flight. The decision, however, cost New Delhi dearly. Maulana, who is believed to be hiding in Karachi, later became the leader of Jaish-e-Mohammed, an organisation which has carried out several terrorist acts against Indian security forces in Kashmir.


title: India–Pakistan relations

text: On 22 December 2000, a group of terrorists belonging to the Lashkar-e-Toiba stormed the famous Red Fort in New Delhi. The Fort houses an Indian military unit and a high-security interrogation cell used both by the Central Bureau of Investigation and the Indian Army. The terrorists successfully breached the security cover around the Red Fort and opened fire at the Indian military personnel on duty killing two of them on spot. The attack was significant because it was carried out just two days after the declaration of the cease-fire between India and Pakistan.


title: India–Pakistan relations

text: In 2002, India claimed again that terrorists from Jammu and Kashmir were infiltrating into India, a claim denied by Pakistan President Pervez Musharraf, who claimed that such infiltration had stopped—India's spokesperson for the External Affairs Ministry did away with Pakistan's claim, calling it "terminological inexactitude." Only two months later, two Kashmiri terrorists belonging to Jaish-e-Mohammed raided the Swami Narayan temple complex in Ahmedabad, Gujarat killing 30 people, including 18 women and five children. The attack was carried out on 25 September 2002, just few days after state elections were held in Jammu and Kashmir. Two identical letters found on both the terrorists claimed that the attack was done in retaliation for the deaths of thousands of Muslims during the Gujarat riots.


title: India–Pakistan relations

text: Two car bombs exploded in south Mumbai on 25 August 2003; one near the Gateway of India and the other at the famous Zaveri Bazaar, killing at least 48 and injuring 150 people. Though no terrorist group claimed responsibility for the attacks, Mumbai Police and RAW suspected Lashkar-e-Toiba's hand in the twin blasts.


title: India–Pakistan relations

text: In an unsuccessful attempt, six terrorists belonging to Lashkar-e-Toiba, stormed the Ayodhya Ram Janmbhomi complex on 5 July 2005. Before the terrorists could reach the main disputed site, they were shot down by Indian security forces. One Hindu worshipper and two policemen were injured during the incident.


title: India–Pakistan relations

text: The 2001 Indian Parliament attack was an attack at the Parliament of India in New Delhi on 13 December 2001, during which fourteen people, including the five men who attacked the building, were killed. The perpetrators were Lashkar-e-Taiba (Let) and Jaish-e-Mohammed (JeM) terrorists. The attack led to the deaths of five terrorists, six Delhi Police personnel, two Parliament Security Service personnel and a gardener, in total 14 and to increased tensions between India and Pakistan, resulting in the 2001–02 India–Pakistan standoff.


title: India–Pakistan relations

text: The 2001–2002 India–Pakistan standoff was a military standoff between India and Pakistan that resulted in the massing of troops on either side of the border and along the Line of Control (LoC) in the region of Kashmir. This was the first major military standoff between India and Pakistan since the Kargil War in 1999. The military buildup was initiated by India responding to a 2001 Indian Parliament attack and the 2001 Jammu and Kashmir legislative assembly attack. India claimed that the attacks were carried out by two Pakistan-based terror groups, the Lashkar-e-Taiba and Jaish-e-Mohammad, both of whom India has said are backed by Pakistan's ISI a charge that Pakistan denied. Tensions de-escalated following international diplomatic mediation which resulted in the October 2002 withdrawal of Indian and Pakistani troops from the international border.


title: India–Pakistan relations

text: The 2007 Samjhauta Express bombings was a terrorist attack targeted on the Samjhauta Express train on 18 February. The Samjhauta Express is an international train that runs from New Delhi, India to Lahore, Pakistan, and is one of two trains to cross the India-Pakistan border. At least 68 people were killed, mostly Pakistani civilians but also some Indian security personnel and civilians.


title: India–Pakistan relations

text: The 2008 Mumbai attacks by ten Pakistani terrorists killed over 173 and wounded 308. The sole surviving gunman Ajmal Kasab who was arrested during the attacks was found to be a Pakistani national. This fact was acknowledged by Pakistani authorities. In May 2010, an Indian court convicted him on four counts of murder, waging war against India, conspiracy and terrorism offences, and sentenced him to death.


title: India–Pakistan relations

text: India blamed the Lashkar-e-Taiba, a Pakistan-based militant group, for planning and executing the attacks. Indian officials demanded Pakistan extradite suspects for trial. They also said that, given the sophistication of the attacks, the perpetrators "must have had the support of some official agencies in Pakistan". In July 2009 Pakistani authorities confirmed that LeT plotted and financed the attacks from LeT camps in Karachi and Thatta. In November 2009, Pakistani authorities charged seven men they had arrested earlier, of planning and executing the assault.


title: India–Pakistan relations

text: On 9 April 2015, the foremost ringleader of the attacks, Zakiur Rehman Lakhvi was granted bail against surety bonds of in Pakistan.

text: The Indian intelligence agency RAW is claimed to be working in cover to malign Pakistan and train & support insurgents for Balochistan conflict.


title: India–Pakistan relations

text: India has a long history of development of nuclear weapons. Origins of India's nuclear program dates back to 1944, when started its nuclear program soon after its independence. In the 1940s–1960s, India's nuclear program slowly matured towards militarisation and expanded the nuclear power infrastructure throughout the country. Decisions on the development of nuclear weapons were made by Indian political leaders after the Chinese invasion and territorial annexation of northern India. In 1967, India's nuclear program was aimed at the development of nuclear weapons, with Indira Gandhi carefully overseeing the development of weapons. In 1971, India gained military and political momentum over Pakistan, after a successful military campaign against Pakistan. Starting preparations for a nuclear test in 1972, India finally exploded its first nuclear bomb in Pokhran test range, codename "Smiling Buddha", in 1974. During the 1980s–90s, India began development of space and nuclear rockets, which marked Pakistan's efforts to engage in the space race with India. Pakistan's own program developed space and nuclear missiles and began unmanned flight tests of its space vehicles in the mid-1990s, which continues in the present.

text: After the defeat in the Indo-Pakistani war of 1971, Pakistan launched its own nuclear bomb program in 1972, and accelerated its efforts in 1974, after India exploded its first nuclear bomb in Pokhran test range, codename "Smiling Buddha". This large-scale nuclear bomb program was directly in response to India's nuclear program. In 1983, Pakistan achieved a major milestone in its efforts after it covertly performed a series of non-fission tests, codename Kirana-I. No official announcements of such cold tests were made by Pakistan government. Over the next several years, Pakistan expanded and modernised nuclear power projects around the country to supply its electricity sector and to provide back-up support and benefit to its national economy. In 1988, a mutual understanding was reached between the two countries in which each pledged not to attack nuclear facilities. Agreements on cultural exchanges and civil aviation were also initiated, also in 1988. Finally, in 1998, India exploded its second nuclear test (see: "Pokhran-II") which invited Pakistan to follow the latter's step and performed its own atomic tests (see "Chagai-I" and "Chagai-II").


title: India–Pakistan relations

text: After the 1971 war, Pakistan and India made slow progress towards the normalisation of relations. In July 1972, Indian Prime Minister Indira Gandhi and Pakistani President Zulfikar Ali Bhutto met in the Indian hill station of Shimla. They signed the Shimla Agreement, by which India would return all Pakistani personnel (over 90,000) and captured territory in the west, and the two countries would "settle their differences by peaceful means through bilateral negotiations." Diplomatic and trade relations were also re-established in 1976.


title: India–Pakistan relations

text: In 1997, high-level Indo-Pakistan talks resumed after a three-year pause. The Prime Ministers of Pakistan and India met twice and the foreign secretaries conducted three rounds of talks. In June 1997, the foreign secretaries identified eight "outstanding issues" around which continuing talks would be focused. The conflict over the status of Kashmir, (referred by India as Jammu and Kashmir), an issue since Independence, remains the major stumbling block in their dialogue. India maintains that the entire former princely state is an integral part of the Indian union, while Pakistan insists that UN resolutions calling for self-determination of the people of the state/province must be taken into account. It however refuses to abide by the previous part of the resolution, which calls for it to vacate all territories occupied.


title: India–Pakistan relations

text: In September 1997, the talks broke down over the structure of how to deal with the issues of Kashmir, and peace and security. Pakistan advocated that the issues be treated by separate working groups. India responded that the two issues be taken up along with six others on a simultaneous basis.


title: India–Pakistan relations

text: Attempts to restart dialogue between the two nations were given a major boost by the February 1999 meeting of both Prime Ministers in Lahore and their signing of three agreements.


title: India–Pakistan relations

text: A subsequent military coup in Pakistan that overturned the democratically elected Nawaz Sharif government in October of the same year also proved a setback to relations.


title: India–Pakistan relations

text: In 2001, a summit was called in Agra; Pakistani President Pervez Musharraf turned up to meet Indian Prime Minister Atal Behari Vajpayee. The talks fell through.


title: India–Pakistan relations

text: On 20 June 2004, with a new government in place in India, both countries agreed to extend a nuclear testing ban and to set up a hotline between their foreign secretaries aimed at preventing misunderstandings that might lead to a nuclear war.


title: India–Pakistan relations

text: After Dr. Manmohan Singh become prime minister of India in May 2004, the Punjab provincial Government declared it would develop Gah, his place of birth, as a model village in his honour and name a school after him. There is also a village in India named Pakistan, despite occasional pressure over the years to change its name the villagers have resisted. Violent activities in the region declined in 2004. There are two main reasons for this: warming of relations between New Delhi and Islamabad which consequently lead to a ceasefire between the two countries in 2003 and the fencing of the Line of Control being carried out by the Indian Army. Moreover, coming under intense international pressure, Islamabad was compelled to take action against the militants' training camps on its territory. In 2004, the two countries also agreed upon decreasing the number of troops present in the region.


title: India–Pakistan relations

text: Under pressure, Kashmiri militant organisations made an offer for talks and negotiations with New Delhi, which India welcomed.


title: India–Pakistan relations

text: India's Border Security Force blamed the Pakistani military for providing cover-fire for the terrorists whenever they infiltrated into Indian territory from Pakistan. Pakistan in turn has also blamed India for providing support to terrorist organisations operating in Pakistan such as the BLA.


title: India–Pakistan relations

text: In 2005, Pakistan's information minister, Sheikh Rashid, was alleged to have run a terrorist training camp in 1990 in N.W. Frontier, Pakistan. The Pakistani government dismissed the charges against its minister as an attempt to hamper the ongoing peace process between the two neighbours.


title: India–Pakistan relations

text: Both India and Pakistan have launched several mutual confidence-building measures (CBMs) to ease tensions between the two. These include more high-level talks, easing visa restrictions, and restarting of cricket matches between the two. The new bus service between Srinagar and Muzaffarabad has also helped bring the two sides closer. Pakistan and India have also decided to co-operate on economic fronts.


title: India–Pakistan relations

text: Some improvements in the relations are seen with the re-opening of a series of transportation networks near the India–Pakistan border, with the most important being bus routes and railway lines.


title: India–Pakistan relations

text: A major clash between Indian security forces and militants occurred when a group of insurgents tried to infiltrate into Kashmir from Pakistan in July 2005. The same month also saw a Kashmiri militant attack on Ayodhya and Srinagar. However, these developments had little impact on the peace process.


title: India–Pakistan relations

text: An Indian man held in Pakistani prisons since 1975 as an accused spy walked across the border to freedom 3 March 2008, an unconditional release that Pakistan said was done to improve relations between the two countries.


title: India–Pakistan relations

text: In 2006, a "Friends Without Borders" scheme began with the help of two British tourists. The idea was that Indian and Pakistani children would make pen pals and write friendly letters to each other. The idea was so successful in both countries that the organisation found it "impossible to keep up". The World's Largest Love Letter was recently sent from India to Pakistan.


title: India–Pakistan relations

text: In December 2010, several Pakistani newspapers published stories about India's leadership and relationship with militants in Pakistan that the papers claimed were found in the United States diplomatic cables leak. A British newspaper, "The Guardian", which had the Wikileaks cables in its possession reviewed the cables and concluded that the Pakistani claims were "not accurate" and that "WikiLeaks [was] being exploited for propaganda purposes."


title: India–Pakistan relations

text: On 10 February 2011, India agreed to resume talks with Pakistan which were suspended after 26/11 Mumbai Attacks. India had put on hold all the diplomatic relations saying it will only continue if Pakistan will act against the accused of Mumbai attacks.


title: India–Pakistan relations

text: On 13 April 2012, following a thaw in relations whereby India gained MFN status in the country, India announced the removal of restrictions on FDI investment from Pakistan to India.


title: India–Pakistan relations

text: The Foreign Minister of Pakistan on 11 July 2012, stated in Phnom Penh that her country is willing to resolve some of the disputes like, Sir Creek and Siachen on the basis of agreements reached in past.


title: India–Pakistan relations

text: On 7 September 2012, Indian External Affairs Minister would pay 3-day visit to Pakistan to review the progress of bilateral dialogue with his Pakistani counterpart.


title: India–Pakistan relations

text: In August 2019, following the approval of the Jammu and Kashmir Reorganisation Bill in the Indian Parliament, which revoked the special status of Jammu and Kashmir, further tension was brought between the two countries, with Pakistan downgrading their diplomatic ties, closing its airspace, and suspending bilateral trade with India.


title: India–Pakistan relations

text: On 25 February 2021, India and Pakistan issued a joint statement indicating that both sides agreed to stop firing at each other at the disputed Line of Control border in Kashmir.


title: India–Pakistan relations

text: In response to the 2001 Gujarat earthquake, Pakistani President Pervez Mushrraf sent a plane load of relief supplies from Islamabad to Ahmedabad. They carried 200 tents and more than 2,000 blankets. Furthermore, the President called Indian PM to express his 'sympathy' over the loss from the earthquake.


title: India–Pakistan relations

text: India offered aid to Pakistan in response to the 2005 Kashmir earthquake on 8 October. Indian and Pakistani High Commissioners consulted with one another regarding cooperation in relief work. India sent 25 tonnes of relief material to Pakistan including food, blankets and medicine. Large Indian companies such as Infosys offered aid up to $226,000. On 12 October, an Ilyushin-76 cargo plane ferried across seven truckloads (about 82 tons) of army medicines, 15,000 blankets and 50 tents and returned to New Delhi. A senior air force official also stated that they had been asked by the Indian government to be ready to fly out another similar consignment.


title: India–Pakistan relations

text: On 14 October, India dispatched the second consignment of relief material to Pakistan, by train through the Wagah Border. The consignment included 5,000 blankets, 370 tents, 5 tons of plastic sheets and 12 tons of medicine. A third consignment of medicine and relief material was also sent shortly afterwards by train. India also pledged $25 million as aid to Pakistan. India opened the first of three points at Chakan Da Bagh, in Poonch, on the Line of Control between India and Pakistan for earthquake relief work.


title: India–Pakistan relations

text: Amid the 2022 Pakistan floods, Indian Prime Minister Narendra Modi expressed his "heartfelt condolences to families of the victims". As of 30 August, it has been reported that the government of India is considering sending relief aid to Pakistan.


title: India–Pakistan relations

text: India has accused some of the most wanted Indian fugitives, such as Dawood Ibrahim, of having a presence in Pakistan. On 11 May 2011, India released a list of 50 "Most Wanted Fugitives" hiding in Pakistan. This was to tactically pressure Pakistan after the killing of Osama bin Laden in his compound in Abbottabad. After two errors in the list received publicity, the Central Bureau of Investigation removed it from their website, pending review. After this incident, the Pakistani interior ministry rejected the list forwarded by India to Islamabad, saying it should first probe if those named in the list were even living in the country.


title: India–Pakistan relations

text: India and Pakistan, particularly Northern India and Eastern Pakistan, to some degree have similar cultures, cuisines and languages due to common Indo-Aryan heritage which span through the two countries and throughout much of the northern subcontinent which also underpin the historical ties between the two. Pakistani singers, musicians, comedians and entertainers have enjoyed widespread popularity in India, with many achieving overnight fame in the Indian film industry Bollywood. Likewise, Indian music and film are very popular in Pakistan. Being located in the northernmost region of South Asia, Pakistan's culture is somewhat similar to that of North India, especially the northwest.


title: India–Pakistan relations

text: The Punjab region was split into Punjab, Pakistan and Punjab, India following the independence and partition of the two countries in 1947. The Punjabi people are today the largest ethnic group in Pakistan and also an important ethnic group of northern India. The founder of Sikhism was born in the modern-day Pakistani Punjab province, in the city of Nankana Sahib. Each year, millions of Indian Sikh pilgrims cross over to visit holy Sikh sites in Nankana Sahib. The Sindhi people are the native ethnic group of the Pakistani province of Sindh. Many Hindu Sindhis migrated to India in 1947, making the country home to a sizeable Sindhi community. In addition, the millions of Muslims who migrated from India to the newly created Pakistan during independence came to be known as the Muhajir people; they are settled predominantly in Karachi and still maintain family links in India.


title: India–Pakistan relations

text: Relations between Pakistan and India have also resumed through platforms such as media and communications. Aman ki Asha is a joint venture and campaign between "The Times of India" and the "Jang Group" calling for mutual peace and development of diplomatic and cultural relations.


title: India–Pakistan relations

text: The India–Pakistan border is the official international boundary that demarcates the Indian states of Punjab, Rajasthan and Gujarat from the Pakistani provinces of Punjab and Sindh. The Wagah border is the only road crossing between India and Pakistan and lies on the famous Grand Trunk Road, connecting Lahore, Pakistan with Amritsar, India. Each evening, the Wagah-Attari border ceremony takes place, in which the flags are lowered and guards on both sides make a pompous military display and exchange handshakes.


title: India–Pakistan relations

text: Hindustani is the lingua franca of North India and Pakistan, as well as the official language of both countries, under the standard registers Hindi and Urdu, respectively. Standard Urdu is mutually intelligible with standard Hindi. Hindustani is also widely understood and used as a lingua franca amongst South Asians including Sri Lankans, Nepalis and Bangladeshis, and is the language of Bollywood, which is enjoyed throughout much of the subcontinent.


title: India–Pakistan relations

text: Apart from Hindustani, India and Pakistan also share a distribution of the Punjabi language (written in the Gurmukhi script in Indian Punjab, and the Shahmukhi script in Pakistani Punjab), Kashmiri language and Sindhi language, mainly due to population exchange. These languages belong to a common Indo-Aryan family that are spoken in countries across the subcontinent.


title: India–Pakistan relations

text: Some Indian and Pakistani people marry across the border at instances. Many Indians and Pakistanis in the diaspora, especially in the United States, intermarry, as there are large cultural similarities between the two countries respectively.


title: India–Pakistan relations

text: In April 2010 a high-profile Pakistani cricketer, Shoaib Malik married the Indian tennis star Sania Mirza. The wedding received much media attention and was said to transfix both India and Pakistan.


title: India–Pakistan relations

text: Cricket and hockey matches between the two (as well as other sports to a lesser degree such as those of the SAARC games) have often been political in nature. During the Soviet invasion of Afghanistan General Zia-ul Haq travelled to India for a bout of "cricket diplomacy" to keep India from supporting the Soviets by opening another front. Pervez Musharaff also tried to do the same more than a decade later but to no avail.


title: India–Pakistan relations

text: From 2012, India stopped playing bilateral cricket series against Pakistan. Now it only plays against them in Asian Cricket Council, ICC events such as ODI, T20 world cups etc. In 2017 then Sport minister of India, Vijay Goel said, that Pakistan have to stop sponsoring terrorists, terrorism and sports can not happen together. Board of Control for Cricket in India (BCCI) also opposed playing with them, citing the reason that, we can not play without the permission of our government. BCCI also do not allow their players to play in IPL.

text: The large size of the Indian diaspora and Pakistani diaspora in many different countries throughout the world has created strong diasporic relations.


title: India–Pakistan relations

text: British Indians and British Pakistanis, the largest and second-largest ethnic minorities living in the United Kingdom respectively, are said to have friendly relations with one another. It is quite common for a "Little India" and a "Little Pakistan" to co-exist in South Asian ethnic enclaves in overseas countries. There are various cities such as Birmingham, Blackburn and Manchester where British Indians and British Pakistanis live alongside each other in peace and harmony. Both Indians and Pakistanis living in the UK fit under the category of British Asian. The UK is also home to the Pakistan & India friendship forum. In the United States, Indians and Pakistanis are classified under the South Asian American category and share many cultural traits. In the US, intermarriage between Indians and Pakistanis is common.

text: The British MEP Sajjad Karim is of Pakistani origin. He is a member of the European Parliament Friends of India Group, Karim was also responsible for opening up Europe to free trade with India. He narrowly escaped the Mumbai attacks at Hotel Taj in November 2008. Despite the atrocity, Karim does not wish the remaining killer Ajmal Kasab to be sentenced to death. He said: "I believe he had a fair and transparent trial and I support the guilty verdict. But I am not a supporter of capital punishment. I believe he should be given a life sentence, but that life should mean life."

text: The size of India-Pakistan trade is very small relative to the size of their economies and the fact that they share a contiguous border. Trade across direct routes has been curtailed formally, so the bulk of India-Pakistan trade is routed through Dubai.


title: Category 5 cable

text: Category 5 cable (Cat 5) is a twisted pair cable for computer networks. Since 2001, the variant commonly in use is the Category 5e specification (Cat 5e). The cable standard provides performance of up to 100 MHz and is suitable for most varieties of Ethernet over twisted pair up to 2.5GBASE-T but more commonly runs at (Gigabit Ethernet) speeds. Cat 5 is also used to carry other signals such as telephone and video.


title: Category 5 cable

text: This cable is commonly connected using punch-down blocks and modular connectors. Most Category 5 cables are unshielded, relying on the balanced line twisted pair design and differential signaling for noise rejection.


title: Category 5 cable

text: The specification for category 5 cable was defined in ANSI/TIA/EIA-568-A, with clarification in TSB-95. These documents specify performance characteristics and test requirements for frequencies up to 100 MHz.


title: Category 5 cable

text: The cable is available in both stranded and solid conductor forms. The stranded form is more flexible and withstands more bending without breaking. Patch cables are stranded. Permanent wiring used in structured cabling is solid-core. The category and type of cable can be identified by the printing on the jacket.


title: Category 5 cable

text: The category 5 specification requires conductors to be pure copper. The industry has seen a rise in non-compliant / counterfeit cables, especially of the Copper Clad Aluminum (CCA) variety. This has exposed the manufacturers or installers of such fake cable to legal liabilities.


title: Category 5 cable

text: The category 5e specification improves upon the category 5 specification by revising and introducing new specifications to further mitigate the amount of crosstalk. The bandwidth (100 MHz) and physical construction are the same between the two, and most Cat 5 cables actually meet Cat 5e specifications, though they are not specifically certified as such. The category 5 was deprecated in 2001 and superseded by the category 5e specification.


title: Category 5 cable

text: The Category 6 specification improves upon the Category 5e specification by extending frequency response and further reducing crosstalk. The improved performance of Cat 6 provides 250 MHz bandwidth. Category 6A cable provides 500 MHz bandwidth. Both variants are backward compatible with Category 5 and 5e cables.


title: Category 5 cable

text: Cable types, connector types and cabling topologies are defined by ANSI/TIA-568. Nearly always, 8P8C modular connectors (often referred to incorrectly as RJ45 connectors) are used for connecting category 5 cable. The cable is terminated in either the T568A scheme or the T568B scheme. The two schemes work equally well and may be mixed in an installation so long as the same scheme is used on both ends of each cable.


title: Category 5 cable

text: Category 5 cable is used in structured cabling for computer networks such as Ethernet over twisted pair. The cable standard prescribes performance parameters for frequencies up to and is suitable for , (Fast Ethernet), (Gigabit Ethernet), . and Ethernet connections require two wire pairs. 1000BASE-T and faster Ethernet connections require four wire pairs. Through the use of power over Ethernet (PoE), power can be carried over the cable in addition to Ethernet data.


title: Category 5 cable

text: Cat 5 is also used to carry other signals such as telephony and video. In some cases, multiple signals can be carried on a single cable; Cat 5 can carry two conventional telephone lines as well as 100BASE-TX in a single cable. The USOC/RJ-61 wiring standard may be used in multi-line telephone connections. Various schemes exist for transporting both analog and digital video over the cable. HDBaseT is one such scheme.


title: Category 5 cable

text: The use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and crosstalk from other pairs.


title: Category 5 cable

text: Most Category 5 cables can be bent at any radius exceeding approximately four times the outside diameter of the cable.


title: Category 5 cable

text: The maximum length for a cable segment is per TIA/EIA 568-5-A. If longer runs are required, the use of active hardware such as a repeater or switch is necessary. The specifications for 10BASE-T networking specify a 100-meter length between active devices. This allows for 90 meters of solid-core permanent wiring, two connectors and two stranded patch cables of 5 meters, one at each end.


title: Category 5 cable

text: Since 1995, solid-conductor UTP cables for backbone cabling is required to be no thicker than 22 American Wire Gauge (AWG) and no thinner than 24 AWG, or 26 AWG for shorter-distance cabling. This standard has been retained with the 2009 revision of ANSI TIA/EIA 568.<ref name="ANSI/TIA/EIA-568-B.2-2001, Commercial Building Telecommunications Cabling Standard"></ref>


title: Category 5 cable

text: Although cable assemblies containing are common, category 5 is not limited to 4 pairs. Backbone applications involve using up to .


title: Category 5 cable

text: The distance per twist is commonly referred to as pitch. Each of the four pairs in a Cat 5 cable has differing precise pitch to minimize crosstalk between the pairs. The pitch of the twisted pairs is not specified in the standard. Measurements on one sample of Cat 5 cable yielded the following results.


title: Category 5 cable

text: Since the pitch of the various colors is not specified in the standard, pitch can vary and should be measured for the batch being used if the cable is being used in a non-Ethernet situation where pitch may be critical.


title: Category 5 cable

text: Some cables are "UV-rated" or "UV-stable" meaning they can be exposed to outdoor UV radiation without significant degradation.


title: Category 5 cable

text: Plenum-rated cables are slower to burn and produce less smoke than cables using a mantle of materials like PVC. Plenum-rated cables may be installed in plenum spaces where PVC is not allowed.


title: Category 5 cable

text: Shielded cables (FTP or STP) are useful for environments where proximity to RF equipment may introduce electromagnetic interference, and can also be used where eavesdropping likelihood should be minimized.


title: Craps

text: Craps is a dice game in which players bet on the outcomes of the roll of a pair of dice. Players can wager money against each other (playing "street craps") or against a bank ("casino craps"). Because it requires little equipment, "street craps" can be played in informal settings. While shooting craps, players may use slang terminology to place bets and actions.


title: Craps

text: In 1788, "Krabs" (later spelled crabs) was an English variation on the dice game hazard (also spelled hasard).


title: Craps

text: Craps developed in the United States from a simplification of the western European game of hazard. The origins of hazard are obscure and may date to the Crusades. Hazard was brought from London to New Orleans in approximately 1805 by the returning Bernard Xavier Philippe de Marigny de Mandeville, the young gambler and scion of a family of wealthy landowners in colonial Louisiana. Although in hazard the dice shooter may choose any number from five to nine to be his main number, de Marigny simplified the game such that the main number is always seven, which is the mathematically optimal choice. Both hazard and its simpler derivative were unfamiliar to and rejected by Americans of his social class, leading de Marigny to introduce his novelty to the local underclass. Field hands taught their friends and deckhands, who carried the new game up the Mississippi River and its tributaries. Celebrating the popular success of his novelty, de Marigny gave the name Rue de Craps to a street in his new subdivision in New Orleans.


title: Craps

text: The central game, called pass from the French word "pas" (meaning "pace" or "step"), has been gradually supplemented over the decades by many companion games which can be played simultaneously with pass. Now applied to the entire collection of games, the name craps derives from an underclass Louisiana mispronunciation of the word "crabs", which in aristocratic London had been the epithet for the numbers two and three . In hazard, both "crabs" are always instant-losing numbers for the first dice roll regardless of the shooter's selected main number. Also in hazard, if the main number is seven then the number twelve is added to the crabs as a losing number on the first dice roll. This structure is retained in the simplified game called pass. All three losing numbers on the first roll of pass are jointly called the craps numbers.


title: Craps

text: For a century after its invention, casinos used unfair dice. In approximately 1907, a dicemaker named John H. Winn in Philadelphia introduced a layout which featured bets on Don't Pass as well as Pass. Virtually all modern casinos use his innovation, which incentivizes casinos to use fair dice.


title: Craps

text: Craps exploded in popularity during World War II, which brought most young American men of every social class into the military. The street version of craps was popular among service members who often played it using a blanket as a shooting surface. Their military memories led to craps becoming the dominant casino game in postwar Las Vegas and the Caribbean. After 1960, a few casinos in Europe, Australia, and Macau began offering craps, and, after 2004, online casinos extended the game's spread globally.


title: Craps

text: Bank craps or casino craps is played by one or more players betting against the casino rather than each other. Both the players and the dealers stand around a large rectangular craps table. Sitting is discouraged by most casinos unless a player has medical reasons for requiring a seat.


title: Craps

text: Players use casino chips rather than cash to bet on the Craps "layout," a fabric surface which displays the various bets. The bets vary somewhat among casinos in availability, locations, and payouts. The tables roughly resemble bathtubs and come in various sizes. In some locations, chips may be called checks, tokens, or plaques.


title: Craps

text: Against one long side is the casino's table bank: as many as two thousand casino chips in stacks of 20. The opposite long side is usually a long mirror. The U-shaped ends of the table have duplicate layouts and standing room for approximately eight players. In the center of the layout is an additional group of bets which are used by players from both ends. The vertical walls at each end are usually covered with a rubberized target surface covered with small pyramid shapes to randomize the dice which strike them. The top edges of the table walls have one or two horizontal grooves in which players may store their reserve chips.


title: Craps

text: The table is run by up to four casino employees: a boxman seated (usually the only seated employee) behind the casino's bank, who manages the chips, supervises the dealers, and handles "coloring up" players (exchanging small chip denominations for larger denominations in order to preserve the chips at a table); two base dealers who stand to either side of the boxman and collect and pay bets to players around their half of the table; and a stickman who stands directly across the table from the boxman, takes and pays (or directs the base dealers to do so) the bets in the center of the table, announces the results of each roll (usually with a distinctive patter), and moves the dice across the layout with an elongated wooden stick.


title: Craps

text: Each employee also watches for mistakes by the others because of the sometimes large number of bets and frantic pace of the game. In smaller casinos or at quiet times of day, one or more of these employees may be missing, and have their job covered by another, or cause player capacity to be reduced.


title: Craps

text: Some smaller casinos have introduced "mini-craps" tables which are operated with only two dealers; rather than being two essentially identical sides and the center area, a single set of major bets is presented, split by the center bets. Responsibility of the dealers is adjusted: the stickman continuing to handle the center bets, and the base dealer handling the other bets as well as cash and chip exchanges.


title: Craps

text: By contrast, in "street craps", there is no marked table and often the game is played with no back-stop against which the dice are to hit. (Despite the name "street craps", this game is often played in houses, usually on an un-carpeted garage or kitchen floor.) The wagers are made in cash, never in chips, and are usually thrown down onto the ground or floor by the players. There are no attendants, and so the progress of the game, fairness of the throws, and the way that the payouts are made for winning bets are self-policed by the players.


title: Craps

text: Each casino may set which bets are offered and different payouts for them, though a core set of bets and payouts is typical. Players take turns rolling two dice and whoever is throwing the dice is called the "shooter". Players can bet on the various options by placing chips directly on the appropriately-marked sections of the layout, or asking the base dealer or stickman to do so, depending on which bet is being made.


title: Craps

text: While acting as the shooter, a player must have a bet on the "Pass" line and/or the "Don't Pass" line. "Pass" and "Don't Pass" are sometimes called "Win" and "Don't Win" or "Right" and "Wrong" bets. The game is played in rounds and these "Pass" and "Don't Pass" bets are betting on the outcome of a round. The shooter is presented with multiple dice (typically five) by the "stickman", and must choose two for the round. The remaining dice are returned to the stickman's bowl and are not used.


title: Craps

text: Each round has two phases: "come-out" and "point". Dice are passed to the left. To start a round, the shooter makes one or more "come-out" rolls. The shooter must shoot toward the farther back wall and is generally required to hit the farther back wall with both dice. Casinos may allow a few warnings before enforcing the dice to hit the back wall and are generally lenient if at least one die hits the back wall. Both dice must be tossed in one throw. If only one die is thrown the shot is invalid. A come-out roll of 2, 3, or 12 is called "craps" or "crapping out", and anyone betting the Pass line loses. On the other hand, anyone betting the Don't Pass line on come out wins with a roll of 2 or 3 and ties (pushes) if a 12 is rolled. Shooters may keep rolling after crapping out; the dice are only required to be passed if a shooter sevens out (rolls a seven after a point has been established). A come-out roll of 7 or 11 is a "natural"; the Pass line wins and Don't Pass loses. The other possible numbers are the point numbers: 4, 5, 6, 8, 9, and 10. If the shooter rolls one of these numbers on the come-out roll, this establishes the "point" – to "pass" or "win", the point number must be rolled again before a seven.


title: Craps

text: The dealer flips a button to the "On" side and moves it to the point number signifying the second phase of the round. If the shooter "hits" the point value again (any value of the dice that sum to the point will do; the shooter doesn't have to exactly repeat the exact combination of the come-out roll) before rolling a seven, the Pass line wins and a new round starts. If the shooter rolls any seven before repeating the point number (a "seven-out"), the Pass line loses, the Don't Pass line wins, and the dice pass clockwise to the next new shooter for the next round. Once a point has been established any multi-roll bet (including Pass and/or Don't Pass line bets and odds) are unaffected by the 2, 3, 11, or 12; the only numbers which affect the round are the established point, any specific bet on a number, or any 7. Any single roll bet is always affected (win or lose) by the outcome of any roll.


title: Craps

text: While the come-out roll may specifically refer to the first roll of a new shooter, any roll where no point is established may be referred to as a come-out. By this definition the start of any new round regardless if it is the shooter's first toss can be referred to as a come-out roll.


title: Craps

text: Any player can make a bet on Pass or Don't Pass as long as a point has not been established, or Come or Don't Come as long as a point is established. All other bets, including an increase in odds behind the Pass and Don't Pass lines, may be made at any time. All bets other than Pass line and Come may be removed or reduced any time before the bet loses. This is known as "taking it down" in craps.


title: Craps

text: The maximum bet for Place, Buy, Lay, Pass, and Come bets are generally equal to table maximum. Lay bet maximum are equal to the table maximum win, so if a player wishes to lay the 4 or 10, he or she may bet twice at amount of the table maximum for the win to be table maximum. Odds behind Pass, Come, Don't Pass, and Don't Come may be however larger than the odds offered allows and can be greater than the table maximum in some casinos. Don't odds are capped on the maximum allowed win some casino allow the odds bet itself to be larger than the maximum bet allowed as long as the win is capped at maximum odds. Single rolls bets can be lower than the table minimum, but the maximum bet allowed is also lower than the table maximum. The maximum allowed single roll bet is based on the maximum allowed win from a single roll.


title: Craps

text: In all the above scenarios, whenever the Pass line wins, the Don't Pass line loses, and vice versa, with one exception: on the come-out roll, a roll of 12 will cause Pass Line bets to lose, but Don't Pass bets are pushed (or "barred"), neither winning nor losing. (The same applies to "Come" and "Don't Come" bets, discussed below.)


title: Craps

text: A player wishing to play craps without being the shooter should approach the craps table and first check to see if the dealer's "On" button is on any of the point numbers.


title: Craps

text: Between dice rolls there is a period for dealers to make payouts and collect losing bets, after which players can place new bets. The stickman monitors the action at a table and decides when to give the shooter the dice, after which no more betting is allowed.


title: Craps

text: When joining the game, one should place money on the table rather than passing it directly to a dealer. The dealer's exaggerated movements during the process of "making change" or "change only" (converting currency to an equivalent in casino cheques) are required so that any disputes can be later reviewed against security camera footage.


title: Craps

text: The dealers will insist that the shooter roll with one hand and that the dice bounce off the far wall surrounding the table. These requirements are meant to keep the game fair (preventing switching the dice or making a "controlled shot"). If a die leaves the table, the shooter will usually be asked to select another die from the remaining three but can request permission to use the same die if it passes the boxman's inspection. This requirement exists to keep the game fair and reduce the chance of loaded dice.


title: Craps

text: There are many local variants of the calls made by the stickman for rolls during a craps game. These frequently incorporate a reminder to the dealers as to which bets to pay or collect.


title: Craps

text: Rolls of 4, 6, 8, and 10 are called "hard" or "easy" (e.g. "six the hard way", "easy eight", "hard ten") depending on whether they were rolled as a "double" or as any other combination of values, because of their significance in center table bets known as the "hard ways". Hard way rolls are so named because there is only one way to roll them (i.e., the value on each die is the same when the number is rolled). Consequently, it is more likely to roll the number in combinations (easy) rather than as a double (hard).


title: Craps

text: The shooter is required to make either a Pass line bet or a Don't Pass bet if he wants to shoot. On the come out roll each player may only make one bet on the Pass or Don't Pass, but may bet both if desired. The Pass Line and Don't Pass bet is optional for any player not shooting. In rare cases, some casinos require all players to make a minimum Pass Line or Don't Pass bet (if they want to make any other bet), whether they are currently shooting or not.


title: Craps

text: The fundamental bet in craps is the Pass line bet, which is a bet for the shooter to win. This bet must be at least the table minimum and at most the table maximum.


title: Craps

text: The Pass line bet is a contract bet. Once a Pass line bet is made, it is always working and cannot be turned "Off", taken down, or reduced until a decision is reached – the point is made, or the shooter sevens out. A player may increase any corresponding odds (up to the table limit) behind the Pass line at any time after a point is established. Players may only bet the Pass line on the come out roll when no point has been established, unless the casino allows put betting where the player can bet Pass line or increase an existing Pass line bet whenever desired and may take odds immediately if the point is already on.


title: Craps

text: A Don't Pass bet is a bet for the shooter to lose ("seven out, line away") and is almost the opposite of the Pass line bet. Like the Pass bet, this bet must be at least the table minimum and at most the table maximum.


title: Craps

text: The Don't Pass bet is a no-contract bet. After a point is established, a player may take down or reduce a Don't Pass bet and any corresponding odds at any time because odds of rolling a 7 before the point is in the player's favor. Once taken down or reduced, however, the Don't Pass bet may not be restored or increased. Because the shooter must have a line bet the shooter generally may not reduce a Don't Pass bet below the table minimum. In Las Vegas, a majority of casinos will allow the shooter to move the bet to the Pass line in lieu of taking it down; however, in other areas such as Pennsylvania and Atlantic City, this is not allowed. Even though players are allowed to remove the Don't Pass line bet after a point has been established, the bet cannot be turned "Off" without being removed. If a player chooses to remove the Don't Pass line bet, he or she can no longer lay odds behind the Don't Pass line. The player can, however, still make standard lay bets on any of the point numbers (4, 5, 6, 8, 9, 10).


title: Craps

text: There are two different ways to calculate the odds and house edge of this bet. The table below gives the numbers considering that the game ends in a push when a 12 is rolled, rather than being undetermined. Betting on Don't Pass is often called "playing the dark side", and it is considered by some players to be in poor taste, or even taboo, because it goes directly against conventional play, winning when most of the players lose.


title: Craps

text: If a 4, 5, 6, 8, 9, or 10 is thrown on the come-out roll (i.e., if a point is established), most casinos allow Pass line players to take odds by placing up to some predetermined multiple of the Pass line bet, behind the Pass line. This additional bet wins if the point is rolled again before a 7 is rolled (the point is made) and pays at the true odds of 2-to-1 if 4 or 10 is the point, 3-to-2 if 5 or 9 is the point, or 6-to-5 if 6 or 8 is the point. Unlike the Pass line bet itself, the Pass line odds bet can be turned "Off" (not working), removed or reduced anytime before it loses. In Las Vegas, generally odds bets are required to be the table minimum. In Atlantic City and Pennsylvania, the combine odds and Pass bet must be table minimum so players can bet the minimum single unit on odds depending on the point. If the point is a 4 or 10 players can bet as little as $1 on odds if the table minimum is low such as is $5, $10 or $15. If the player requests the Pass odds be not working ("Off") and the shooter sevens-out or hits the point, the Pass line bet will be lost or doubled and the Pass odds returned.


title: Craps

text: Individual casinos (and sometimes tables within a casino) vary greatly in the maximum odds they offer, from single or double odds (one or two times the Pass line bet) up to 100x or even unlimited odds. A variation often seen is "3-4-5X Odds", where the maximum allowed odds bet depends on the point: three times if the point is 4 or 10; four times on points of 5 or 9; or five times on points of 6 or 8. This rule simplifies the calculation of winnings: a maximum Pass odds bet on a 3–4–5× table will always be paid at six times the Pass line bet regardless of the point.


title: Craps

text: As odds bets are paid at true odds, in contrast with the Pass line which is always even money, taking odds on a minimum Pass line bet lessens the house advantage compared with betting the same total amount on the Pass line only. A maximum odds bet on a minimum Pass line bet often gives the lowest house edge available in any game in the casino. However, the odds bet cannot be made independently, so the house retains an edge on the Pass line bet itself.


title: Craps

text: If a player is playing Don't Pass instead of pass, they may also lay odds by placing chips behind the Don't Pass line. If a 7 comes before the point is rolled, the odds pay at true odds of 1-to-2 if 4 or 10 is the point, 2-to-3 if 5 or 9 is the point, or 5-to-6 if 6 or 8 is the point. Typically the maximum lay bet will be expressed such that a player may win up to an amount equal to the maximum odds multiple at the table. If a player lays maximum odds with a point of 4 or 10 on a table offering five-times odds, he would be able to lay a maximum of ten times the amount of his Don't Pass bet. At 5x odds table, the maximum amount the combined bet can win will always be 6x the amount of the Don't Pass bet. Players can bet table minimum odds if desired and win less than table minimum. Like the Don't Pass bet the odds can be removed or reduced. Unlike the Don't Pass bet itself, the Don't Pass odds can be turned "Off" (not working). In Las Vegas generally odds bets are required to be the table minimum. In Atlantic City and Pennsylvania, the combine lay odds and Don't Pass bet must be table minimum so players may bet as little as the minimum two units on odds depending on the point. If the point is a 4 or 10 players can bet as little as $2 if the table minimum is low such as $5, $10 or $15 tables. If the player requests the Don't Pass odds to be not working ("Off") and the shooter hits the point or sevens-out, the Don't Pass bet will be lost or doubled and the Don't Pass odds returned. Unlike a standard lay bet on a point, lay odds behind the Don't Pass line does not charge commission (vig).


title: Craps

text: A Come bet can be visualized as starting an entirely new Pass line bet, unique to that player. Like the Pass Line each player may only make one Come bet per roll, this does not exclude a player from betting odds on an already established Come point. This bet must be at least the table minimum and at most the table maximum. Players may bet both the Come and Don't Come on the same roll if desired. Come bets can only be made after a point has been established since, on the come-out roll, a Come bet would be the same thing as a Pass line bet. A player making a Come bet will bet on the first point number that "comes" from the shooter's next roll, regardless of the table's round. If a 7 or 11 is rolled on the first round, it wins. If a 2, 3, or 12 is rolled, it loses. If instead the roll is 4, 5, 6, 8, 9, or 10, the Come bet will be moved by the base dealer onto a box representing the number the shooter threw. This number becomes the "come-bet point" and the player is allowed to take odds, just like a Pass line bet. Also like a Pass line bet, the come bet is a contract bet and is always working, and cannot be turned "Off", removed or reduced until it wins or loses. However, the odds taken behind a Come bet can be turned "Off" (not working), removed or reduced anytime before the bet loses. In Las Vegas generally odds bets are required to be the table minimum. In Atlantic City and Pennsylvania, the combine odds and Pass bet must be table minimum so players can bet the minimum single unit depending on the point. If the point is a 4 or 10, players can bet as little as $1 if the table minimum is low such as $5, $10, or $15 minimums. If the player requests the Come odds to be not working ("Off") and the shooter sevens-out or hits the Come bet point, the Come bet will be lost or doubled and the Come odds returned. If the casino allows put betting a player may increase a Come bet after a point has been established and bet larger odds behind if desired. Put betting also allows a player to bet on a Come and take odds immediately on a point number without a Come bet point being established.


title: Craps

text: The dealer will place the odds on top of the come bet, but slightly off center in order to differentiate between the original bet and the odds. The second round wins if the shooter rolls the come bet point again before a seven. Winning come bets are paid the same as winning Pass line bets: even money for the original bet and true odds for the odds bet. If, instead, the seven is rolled before the come-bet point, the come bet (and any odds bet) loses.


title: Craps

text: Because of the come bet, if the shooter makes their point, a player can find themselves in the situation where they still have a come bet (possibly with odds on it) and the next roll is a come-out roll. In this situation, odds bets on the come wagers are usually presumed to be not working for the come-out roll. That means that if the shooter rolls a 7 on the come-out roll, any players with active come bets waiting for a come-bet point lose their initial wager but will have their odds bets returned to them.


title: Craps

text: If the come-bet point is rolled on the come-out roll, the odds do not win but the come bet does and the odds bet is returned (along with the come bet and its payoff). The player can tell the dealer that they want their odds working, such that if the shooter rolls a number that matches the come point, the odds bet will win along with the come bet, and if a seven is rolled, both lose.


title: Craps

text: Many players will use a come bet as "insurance" against sevening out: if the shooter rolls a seven, the come bet pays 1:1, offsetting the loss of the Pass line bet. The risk in this strategy is the situation where the shooter does not hit a seven for several rolls, leading to multiple come bets that will be lost if the shooter eventually sevens out.


title: Craps

text: In the same way that a come bet is similar to a Pass line bet, a Don't Come bet is similar to a Don't Pass bet. Like the come, the Don't Come can only be bet after a point has already been established as it is the same as a Don't Pass line bet when no point is established. This bet must be at least the table minimum and at most the table maximum. A Don't Come bet is played in two rounds. If a 2 or 3 is rolled in the first round, it wins. If a 7 or 11 is rolled, it loses. If a 12 is rolled, it is a push (subject to the same 2/12 switch described above for the Don't Pass bet). If, instead, the roll is 4, 5, 6, 8, 9, or 10, the Don't Come bet will be moved by the base dealer onto a box representing the number the shooter threw. The second round wins if the shooter rolls a seven before the Don't Come point. Like the Don't Pass each player may only make one Don't Come bet per roll, this does not exclude a player from laying odds on an already established Don't Come points. Players may bet both the Don't Come and Come on the same roll if desired.


title: Craps

text: The player may lay odds on a Don't Come bet, just like a Don't Pass bet; in this case, the dealer (not the player) places the odds bet on top of the bet in the box, because of limited space, slightly offset to signify that it is an odds bet and not part of the original Don't Come bet. Lay odds behind a Don't Come are subject to the same rules as Don't Pass lay odds. Unlike a standard lay bet on a point, lay odds behind a Don't Come point does not charge commission (vig) and gives the player true odds. Like the Don't Pass line bet, Don't Come bets are no-contract, and can be removed or reduced after a Don't Come point has been established, but cannot be turned off ("not working") without being removed. A player may also call, "No Action" when a point is established, and the bet will not be moved to its point. This play is not to the player's advantage. If the bet is removed, the player can no longer lay odds behind the Don't Come point and cannot restore or increase the same Don't Come bet. Players must wait until next roll as long as a Pass line point has been established (players cannot bet Don't Come on come out rolls) before they can make a new Don't Come bet. Las Vegas casinos which allow put betting allows players to move the Don't Come directly to any Come point as a put; however, this is not allowed in Atlantic City or Pennsylvania. Unlike the Don't Come bet itself, the Don't Come odds can be turned "Off" (not working), removed, or reduced if desired. In Las Vegas, players generally must lay at least table minimum on odds if desired and win less than table minimum; in Atlantic City and Pennsylvania a player's combined bet must be at least table minimum, so depending on the point number players may lay as little as 2 minimum units (e.g. if the point is 4 or 10). If the player requests the Don't Come odds be not working ("Off") and the shooter hits the Don't Come point or sevens-out, the Don't Come bet will be lost or doubled and the Don't Come odds returned.


title: Craps

text: Winning Don't Come bets are paid the same as winning Don't Pass bets: even money for the original bet and true odds for the odds lay. Unlike come bets, the odds laid behind points established by Don't Come bets are always working including come out rolls unless the player specifies otherwise.


title: Craps

text: These are bets that may not be settled on the first roll and may need any number of subsequent rolls before an outcome is determined.


title: Craps

text: Most multi-roll bets may fall into the situation where a point is made by the shooter before the outcome of the multi-roll bet is decided. These bets are often considered "not working" on the new come-out roll until the next point is established, unless the player calls the bet as "working."


title: Craps

text: Casino rules vary on this; some of these bets may not be callable, while others may be considered "working" during the come-out. Dealers will usually announce if bets are working unless otherwise called off. If a non-working point number placed, bought or laid becomes the new point as the result of a come-out, the bet is usually refunded, or can be moved to another number for free.


title: Craps

text: Players can bet any point number (4, 5, 6, 8, 9, 10) by placing their wager in the come area and telling the dealer how much and on what number(s), "30 on the 6", "5 on the 5", or "25 on the 10". These are typically "Place Bets to Win". These are bets that the number bet on will be rolled before a 7 is rolled. These bets are considered working bets, and will continue to be paid out each time a shooter rolls the number bet. On a come-out roll, a place bet is considered to be not in effect unless the player who made it specifies otherwise. This bet may be removed or reduced at any time until it loses; in the latter case, the player must abide by any table minimums.


title: Craps

text: Place bets to win pay out at slightly worse than the true odds: 9-to-5 on points 4 or 10, 7-to-5 on points 5 or 9, and 7-to-6 on points 6 or 8. The place bets on the outside numbers (4,5,9,10) should be made in units of $5, (on a $5 minimum table), in order to receive the correct exact payout of $5 paying $7 or $5 paying $9. The place bets on the 6 & 8 should be made in units of $6, (on a $5 minimum table), in order to receive the correct exact payout of $6 paying $7. For the 4 and 10, it is to the player's advantage to 'buy' the bet (see below).


title: Craps

text: An alternative form, rarely offered by casinos, is the "place bet to lose." This bet is the opposite of the place bet to win and pays off if a 7 is rolled before the specific point number. The place bet to lose typically carries a lower house edge than a place bet to win. Payouts are 4–5 on points 6 or 8, 5–8 on 5 or 9, and 5–11 on 4 or 10.


title: Craps

text: Players can also buy a bet which are paid at true odds, but a 5% commission is charged on the amount of the bet. Buy bets are placed with the shooter betting at a specific number will come out before a player sevens out. The buy bet must be at least table minimum excluding commission; however, some casinos require the minimum buy bet amount to be at least $20 to match the $1 charged on the 5% commission. Traditionally, the buy bet commission is paid no matter what, but in recent years a number of casinos have changed their policy to charge the commission only when the buy bet wins. Some casinos charge the commission as a one-time fee to buy the number; payouts are then always at true odds. Most casinos usually charge only $1 for a $25 green-chip bet (4% commission), or $2 for $50 (two green chips), reducing the house advantage a bit more. Players may remove or reduce this bet (bet must be at least table minimum excluding vig) anytime before it loses. Buy bets like place bets are not working when no point has been established unless the player specifies otherwise.


title: Craps

text: Where commission is charged only on wins, the commission is often deducted from the winning payoff—a winning $25 buy bet on the 10 would pay $49, for instance. The house edges stated in the table assume the commission is charged on all bets. They are reduced by at least a factor of two if commission is charged on winning bets only.


title: Craps

text: A lay bet is the opposite of a buy bet, where a player bets on a 7 to roll before the number that is laid. Players may only lay the 4, 5, 6, 8, 9, or 10 and may lay multiple numbers if desired. Just like the buy bet lay bets pay true odds, but because the lay bet is the opposite of the buy bet, the payout is reversed. Therefore, players get 1 to 2 for the numbers 4 and 10, 2 to 3 for the numbers 5 and 9, and 5 to 6 for the numbers 6 and 8. A 5% commission (vigorish, vig, juice) is charged up front on the possible winning amount. For example: A $40 Lay Bet on the 4 would pay $20 on a win. The 5% vig would be $1 based on the $20 win. (not $2 based on the $40 bet as the way buy bet commissions are figured.) Like the buy bet the commission is adjusted to suit the betting unit such that fraction of a dollar payouts are not needed. Casinos may charge the vig up front thereby requiring the player to pay a vig win or lose, other casinos may only take the vig if the bet wins. Taking vig only on wins lowers house edge. Players may removed or reduce this bet (bet must be at least table minimum) anytime before it loses. Some casinos in Las Vegas allow players to lay table minimum plus vig if desired and win less than table minimum. Lay bet maximums are equal to the table maximum win, so if a player wishes to lay the 4 or 10, he or she may bet twice at amount of the table maximum for the win to be table maximum. Other casinos require the minimum bet to win at $20 even at the lowest minimum tables in order to match the $1 vig, this requires a $40 bet. Similar to buy betting, some casinos only take commission on win reducing house edge. Unlike place and buy bets, lay bets are always working even when no point has been established. The player must specify otherwise if he or she wishes to have the bet not working.


title: Craps

text: If a player is unsure of whether a bet is a single or multi-roll bet, it can be noted that all single-roll bets will be displayed on the playing surface in one color (usually red), while all multi-roll bets will be displayed in a different color (usually yellow).


title: Craps

text: A put bet is a bet which allows players to increase or make a Pass line bet after a point has been established (after come-out roll). Players may make a put bet on the Pass line and take odds immediately or increase odds behind if a player decides to add money to an already existing Pass line bet. Put betting also allows players to increase an existing come bet for additional odds after a come point has been established or make a new come bet and take odds immediately behind if desired without a come bet point being established. If increased or added put bets on the Pass line and Come cannot be turned "Off", removed or reduced, but odds bet behind can be turned "Off", removed or reduced. The odds bet is generally required to be the table minimum. Player cannot put bet the Don't Pass or Don't Come. Put betting may give a larger house edge over place betting unless the casino offers high odds.


title: Craps

text: Put bets are better than place bets (to win) when betting more than 5-times odds over the flat bet portion of the put bet. For example, a player wants a $30 bet on the six. Looking at two possible bets: 1) Place the six, or 2) Put the six with odds. A $30 place bet on the six pays $35 if it wins. A $30 put bet would be a $5 flat line bet plus $25 (5-times) in odds, and also would pay $35 if it wins. Now, with a $60 bet on the six, the place bet wins $70, where the put bet ($5 + $55 in odds) would pay $71. The player needs to be at a table which not only allows put bets, but also high-times odds, to take this advantage.
