TTIP and TRING pins via a coupling transformer. The line driver can handle both long (CSU) and short

haul (DSX-1) lines.

Reader’s Note

This data sheet assumes a particular nomenclature of the T1 operating environment. In each 125 us frame,

there are 24 8-bit channels plus a framing bit. It is assumed that the framing bit is sent first followed by

channel 1. Each channel is made up of 8 bits which are numbered 1 to 8. Bit number 1 is the MSB and is

transmitted first. Bit number 8 is the LSB and is transmitted last. Throughout this data sheet, the

following abbreviations will be used:

D4

SLC-96

ESF

B8ZS
