NT8D35 Network module
This module provides the network switching functions in the Meridian 1
Option 81C, Meridian 1 PBX 81C CP PIV, and CS 1000M MG.
Two Network modules are required to make a full network group of 32
loops. A maximum of 16 Network modules (eight network groups) can be
configured in the Meridian 1 Option 81C, CS 1000M MG, and Meridian
1 PBX 81C CP PIV.
The Network module houses up to four NT8D04 Superloop Network Cards,
for a total of 16 network loops. Superloop network cards are cabled to the
backplane of an IPE module. In a typical configuration, one Conference/TDS
card is configured in the module, leaving 14 voice/data loops available.
In CS 1000M MG and Meridian 1 PBX 81C CP PIV, the Conference/TDS
cards are located in the Core/Network module. The Clock Controller must
be installed in slot 13.
Figure 9 "NT8D35 Network module" (page 30) shows the cards housed in
the module.
