Network cables are required to connect peripheral shelves in the cabinet to
network cards in the column. The number of cables required depends on the
number of network cards installed. These are the cables:
— NT8D86AC cables that connect the network card and the peripheral
buffer card to the I/O panel
— NT9J96 cables that connect the I/O panel in the Core/Network module to
the cabinet I/O panel
An NT8D01 Controller card is provided to support the intelligent peripheral
cards in the new IPE module. If analog peripheral cards are used in the IPE
module, one NT8D21 Ringing Generator must be installed.
