T1 connections
T1 signaling for all 24 channels is transmitted over P2 connector pins 1, 3,
9, and 11 as shown in
Table 84 "Lineside T1 card - NT5D13AA connector
pinouts" (page 199) . 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
