If you have multiple nests, the MTU-M is installed in the top nest (Nest 1) and that
nest is then referred to as the primary nest. Additional expansion nests are
connected to the primary nest through RJ48 connectors located on the nest rear
panel (refer to Chapter 2,
Nest card termination units are referred to as xTU-C/Rs. The x refers to either H
for HDSL termination units or S for SDSL termination units. The xTUs configured
as central office/site (CO) are referred to as xTU-Cs. The xTU-C's associated
CP-configured units are referred to a xTU-Rs. The MTU-M monitors only those
xTUs configured as CO. The status of the associated CP-configured unit ( xTU-R),
nest-mounted or standalone, is monitored through the xTU-C.
The Hotwire Model 7900 Nest and nest card termination units are described in
separate user's guides. Refer to
for information on other manuals.
