Installation

This section describes how to install and test the Lineside T1 card.

When installed, the Lineside T1 card occupies two card slots. It can be
installed into an NT8D37 IPE module.

When installing the Lineside T1 card into NT8D37 IPE module, determine
the vintage level module. If the 25-pair I/O connectors are partially split
between adjacent IPE card slots, the Lineside T1 card works only in card
slots where Unit 0 of the motherboard card slot appears on the first pair of
the 25-pair I/O connector.

Certain vintage levels carry dedicated 25-pair I/O connectors only for card
slots 0, 4, 8, and 12. These vintage levels are cabled with only 16 pairs
of wires from each card slot to the I/O panel. Some of the 25-pair I/O
connectors are split between adjacent card slots. Other vintage levels
cable each card slot to the I/O panel using a unique, 24-pair connector on
the I/O panel. In these vintage levels, the Lineside T1 card can be installed
in any available pair of card slots. However, because of the lower number
of wire pairs cabled to the I/O panel in the lower vintage level, only certain
card slots are available to the Lineside T1 card.

See

Table 81 "Lineside T1 card - NT8D37 IPE module vintage level port

cabling" (page 190)

for the vintage level information for the NT8D37 IPE

modules.
