Introduction
Nortel is pleased to introduce the NT8D14CA Universal Trunk (XUT) card as
a replacement for the NT8D14BB card. The NT8D14CA has been 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.
