What is a digital telephone line? What is a digital telephone line? A digital telephone line or digital trunk is a type of telephone line that carries voice and/or data by using digital sampling.1 vs. PRI. PRI divides a T1 digital signal into 24 channels of 64 Kbps capacity per channel. 23 of these channels can be assigned as one telephone call each, the equivalent of having 23 separate telephone lines. The 24th channel is used for signaling information and special features such as caller ID.

- You can get phone service for your home or business with either analog phone or digital phone. The two services use different technologies and methods to carry and deliver voice signals.igital phone service provides a higher quality sound. Digital phone service uses cable or a digital phone network to make phone calls. The voice signals are compressed and unnecessary frequency bands are taken out as the audio travels. This creates a better sound quality, compared to analog phone service.

WHAT DOES DSL STAND FOR? Telephone Lines. When you connect to the Internet, you might connect through a regular modem, through a local-area network connection in your office, through a cable modem or through a digital subscriber line (DSL) connection. DSL is a very high-speed connection that uses the same wires as a regular telephone line. Here are some advantages of DSL: 1  You can leave your Internet connection open and still use the phone line for voice calls. 2  The speed is much higher than a regular modem. 3  DSL doesn't necessarily require new wiring; it can use the phone line you already have.

Internet access A Guide To Computer Modems. The Basics. Most phone lines were designed to carry tonal (analog) signals. The Public Switched Telephone Network (PSTN) picks up these tonal signals, and usually converts them into digital signals to transfer them from one Central Office (CO) to another. On the other end, the digital signals are converted back into an analog signal. How does a computer use a phone line? Modem is an acronym for MOdulator/DEModulator. It converts the digital signal from your computer into an analog signal that can be carried by the phone line, and vice versa. It is also possible to get a digital line (ISDN) installed in your home, but you would need an adapter in order to resolve the different digital signals.
