DC-poweredmodules do not require an MPDU because a switch on each power supplyperforms 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 moduleThis module provides common control and network interface functions.With the CS 1000M MGand the Meridian 1 PBX 81C CP PIV, twoCore/Net modules are installed side-by-side.
