Cabling the Lineside T1 card

After configuring 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).

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).
