Introduction
Nortel is pleased to introduce the NT8D14CA Universal Trunk (XUT) card as a replacement
for the NT8D14BB card. The NT8D14CA is modified to add a longer loop capability for CAMA
trunk applications.
The NT8D14CA comes equipped with a set of 2 jumpers for each hybrid that should be set to
the longer loop length (LL) when the trunk is used in a CAMA application. The jumpers are
numbered P35 to P50 and are set to the shorter loop length (SL) position when it comes from
the factory. For each hybrid, both jumpers should be changed to the LL position only if used
as a CAMA trunk. Otherwise the jumpers should be left to the SL position.
The NT8D14 Universal Trunk card interfaces eight analog trunk lines to the system. Each trunk
interface is independently configured by software control using the Trunk Administration
program LD 14.
You can install this card in any IPE slot.
