System modules

Each type of module is available in AC-powered and DC-powered versions (except the NT8D36 InterGroup module that does not require power). AC-power modules generally require a module power distribution unit (MPDU) to provide circuit breakers for the power supplies. DC-powered modules do not require an MPDU because a switch on each power supply performs the same function as the MPDU circuit breakers.

Note: In the UK, DC-powered modules must be used.

The figures in this chapter show a typical configuration for each module. DC power is represented in these examples.

NT4N41 Core/Network module

This module provides common control and network interface functions. With the CS 1000M MGand the Meridian 1 PBX 81C CP PIV, two Core/Net modules are installed side-by-side. With the CS 1000M SGand the Meridian 1 PBX 61C CP PIV, the modules are stacked or mounted side-by-side.

One section of this module houses the common control complex (CPU, memory, up to four cCNI 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: cCNI 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.
