T1/PRI Network Interface Module (P/N 1200307L1/L2), USOC RJ-48C
The T1/PRI Network Interface Module provides a single T1/PRI port (see Table 8 for the pinout) and 
complies with the applicable ANSI and AT&T
®
 standards. The T1/PRI Network Interface Module 
provides the following functions:
AMI or B8ZS coding
Manual line build-out
D4 or ESF framing
Network performance monitoring and reporting
Test loopbacks with QRSS generation and checking
Extensive self-testing
Test Interface
The MON 
IN
 and 
OUT
 Bantam test jacks provide a bridged access jack for nonintrusive monitoring of the 
incoming T1. When connected to this jack, configure the test equipment for bridged termination.

The E1/PRA Network Interface Module provides a single E1/PRA port (see Table 9 on page 35) that pro-
vide the following functions:
AMI or HDB3 coding
Manual line build-out
NFAS, FAS, TS16 MF and CRC-4 framing
Supports CCS or CAS signaling
Network performance monitoring and reporting
Test loopbacks with QRSS generation and checking
Extensive self-testing
