Product description

The CS 1000M MG and Meridian 1 PBX 81C CP PIV support a Fiber
Network Fabric network system with a FIJI card in slots 8 and 9 on the
Net side of the Core/Net module.

NT5D21 Core/Network module

This module provides common control and network interface functions in
CS 1000M SG, CS 1000M MG, CS 1000M HG, Meridian 1 Option 51C,
Meridian 1 Option 61C, and Meridian 1 Option 81C.

Two Core/Network modules are required in the CS 1000M SG, CS 1000M
MG, Meridian 1 Option 81C, and Meridian 1 Option 61C systems to provide
redundant common control operation. If a failure occurs in one module, the
function is transferred to the appropriate circuit cards in the other module
without a loss of service. One Core/Network module is required in the CS
1000M HG or Option 51C system.

One section of this module houses the common control complex (CPU,
memory, up to three CNI cards, and mass storage functions). The other
section supports a Conference card, one Peripheral Signaling card, one
3-Port Extender card, and optional network cards.

Note: CNI card slots 13 and 14 remain empty.

Each Core/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.

housed in the NT5D21 Core/Network module as configured for Meridian 1
Option 61C.
