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
Superframe (12 frames per multiframe) Multiframe Structure
SLC-96
Subscriber Loop Carrier - 96 Channels (SLC-96 is an AT&T registered trademark)
ESF
Extended Superframe (24 frames per multiframe) Multiframe Structure
B8ZS
Bipolar with 8 0 Subsitution
CRC
Cyclical Redundancy Check
Ft
Terminal Framing Pattern in D4
Fs
Signaling Framing Pattern in D4
FPS
Framing Pattern in ESF
MF
Multiframe
BOC
Bit Oriented Code
HDLC
High Level Data Link Control
FDL
Facility Data Link
