 During the Fall of 2006, the Georgia State University underwent a $4,000,000 network renovation where all of the networking equipment across the campus was upgraded and replaced without any detectable downtime to the delivery of campus network services of the TOC facility.This network upgrade has been done in preparation of a new AVAYA IP Telephony (IPT or VoIP) system that replaced the University's analog POTS telecommunications system in the summer of 2007.GSU's TOC is home to the GALILEO Interconnected Libraries, the New Georgia Encyclopedia, the online presence of the Jimmy Carter Library, and three SURAGrid-networked IBM P575 Supercomputers.
