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.
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.
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.
