T1 connections

T1 signaling for all 24 channels is transmitted overP2 connector pins 1, 3,

9, and 11 as shown in Table98 "Lineside T1 card - NT5D13AA connector

pinouts" (page 208). Plug the DB15 male connector labeled "P2" into the

T1 link. T1 transmit and receive pairs must be turned over between the

Lineside T1 card and CPE equipment that is hardwired without carrier

facilities. If the Lineside T1 card is connected through T1 carrier facilities,

the transmit and receive pairs must be wired straight through to the RJ48
