The Lineside T1 card is cabled from its backplane connector through
connections from the motherboard circuit card only (no cable connections
are made from the daughterboard circuit card) to the input/output (I/O)
panel on the rear of the IPE module. The connections from the Lineside
T1 card to the I/O panel are made with the NT8D81AA Tip and Ring cables
provided with the IPE module.

After setting the dip switches and installing the Lineside T1 card into the
selected card slots, the Lineside T1 card is ready to be cabled to the CPE
or CSU equipment. Connections can also be made to the MMI terminal or
modem (optional), an external alarm (optional), and other Lineside T1 cards
for daisy-chain use of the MMI terminal (optional).

Cabling from the I/O panel with the NT5D13AA Lineside T1 I/O
cable

Usually, the I/O panel is connected to the T1 link and other external devices
through the NT5D13AA Lineside T1 I/O cable. See

Figure 34 "Lineside T1

. This

cable consists of a 25-pair amphenol connector (P1) on one end which
plugs into the I/O panel. The other end has 4 connectors:
