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 MGand 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 28) shows the cards housed in the module.
