Rsc-M Maintenance Introduction - Nortel DMS 100 Series Maintenance Manual

1 RSC-M maintenance introduction

The Remote Switch Center Multi-Access (RSC-M) is a remote common
peripheral module (CPM) designed to support time division multiplexers
(TDM). The support of European Telecommunications Standards Institute
(ETSI) protocols by Digital Multiplex Systems (DMS) provides plain old
telephone services (POTS) on international multi-vendor remotes.
The RSC-M is from the Remote Switching Center Overseas (RCO2) shelf, a
component of the Remote Switching Center-SONET (RSC-S) cabinet. Within
this document, references to the RCO2 shelf apply to the shelf configured in
the RSC-M cabinet. For the purpose of explanation, the document will refer
to the shelf as an RSC-M shelf.
An RSC-M connects to a DMS-100 host peripheral, the line group controller
offshore (LGCOi+). The LGCOi+ uses 2 to 16 pulse code modulation
(PCM30) links. Datafill tables and MAP displays indicate that the PLGC is
the host peripheral. This document refers to the LGCOi+ i as a PCM30 line
group controller (PLGC).
Note: One LGCOi+ supports a maximum of two RSC-M main and
extension shelves.
The stand-alone version of the RSC-M referred to in this document will
provide the following protocols. The protocols refer to the lines terminating
on remote multi-vendor AMC nodes:

The RSC-M cabinet supports only channel associated signaling (CAS) lines.
The CAS maintenance messaging for the RSC-M peripheral will indicate
Global Peripheral Platform (GPP) or RCO2 as the PM type. The software
