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.
