5. 61202060L4 1 Chapter 1 Introduction T1 FT1 OVERVIEW T1 digital communication links have been used by the telephone companies telcos for voice transmission since the early sixties The D4 channel bank is an example of a T1 digital carrier system that was introduced in the mid seventies and is still widely used by the telcos Communication demands of businesses continued to grow to the point that the telcos began offering T1 service directly to the public D4 channel banks began to be used for T1 in corporate network topographies for voice The technological advances in computer development also created a demand for T1 data communication which now is a large part of the T1 traffic T1 Service Offerings Tl is a digital service that is delivered to the user over two pairs of wires from the service provider The signal operates at 1 544 mega bits per second Mbps and is usually extended by repeaters that are installed about every mile after the first 6000 feet The T1 signal is divided into 24 time slots or digital signal level zeros DSOs which operate at 64 kilo bits per seconds kbps Each time slot is occupied by digitized voice or by data The T1 signal originally used a type of framing known as D4 Superframe which identifies how the T1 is multiplexed Extended Superframe ESF is an enhancement of that framing format ESF provides a non disruptive means of full time monitoring on the digital facility It was originally used by the servi
