Dual T1/PRI Card

The dual T1/PRI card routes incoming digital T1 lines to the 6-port or 12-port modules. The

dual T1/PRI card provides RJ-48C connectors to terminate trunks. The dual T1/PRI card

performs all necessary equalization and gain functions to support 6000 feet of 24-gauge

unshielded cable. This card complies with all Bell Core standards relating to T1

(ANSI T1.403) alarms, loopbacks, and error detection. The dual T1/PRI card is equipped

with integrated CSUs.

The dual T1/PRI card handles up to 48 digital signal level 0 (DS-0) channels from two

trunks. Each channel carries either a pulse code modulation (PCM)–encoded voice channel

or digital data. The dual T1/PRI card supports 64-kbps clear channel operation for data or

voice channels and feature group B operation for voice channels.
