SWITCH DISTINCTIVE REMOTE MODULE
2.1 Overview
The 5ESS Switch Distinctive Remote Module (DRM) is a remote architecture based on
the SM-2000 architecture with no back-hauled voice or data traffic. Each DRM
consists of a single SM-2000, an Administrative Workstation and a commercially
remoted
Ethernet
1
connection to the 5ESS switch via the ASM referred to as the
“Host.” A Switching Complex provides a common set of maintenance terminals and
data links off of an Administrative Services Module (ASM), which can support a
5ESS
switch (3B21D, CM2, and SMs/SM-2000s) and up to 15 DRMs.
Note: Although local terminal interfaces and operating support systems (discussed
later in this chapter) can be used for monitoring and maintaining a DRM, it is
recommended that these functions be performed via the terminals and data links
through the ASM. See “ASM Interface for DRM Monitoring and Maintenance,” Section
2.2.
The DRM provides services such as Plain Old Telephone Service (POTS), equal access,
Integrated Services Digital Network (ISDN) and Centralized Telephone
Communications Exchange Service (CENTREX).
The DRM provides:
•
A central monitoring and maintenance center for up to 15 DRMs
•
Virtually non-blocking access between non-concentrated switch terminations
•
Integration of voice and digital data services into a single switch
•
Direct digital interfacing with digital facility terminations
•
Signaling and transmission treatment by an interface unit
•
Testing access to modular metallic facilities as an integral part of the interface
units
•
Evolution potential to full-size 5ESS switch.
•
The OIU OC-3 SONET capability is supported on the VCDX and DRM platforms.
High capacity DRM can support up to 55K lines and 10K trunks under the 65K
maximum circuits limitation. The high capacity DRM configuration should be an
SM2K (SMPU4 or SMPU5) or SM-XC (SMU6) that is equipped with a
Netra

AWS, a Core 700 Processor, and a MHPPC. The analog lines will be terminated on
XAIUs. PSU2’s will be used for SS7 signaling.
2.1.1 Using 5ESS Switch Core Documentation
This user’s guide should always be referenced first by DRM owners. This document
contains all DRM specific procedures which do not appear in any other
5ESS switch
documentation. If further detail or explanation is required or if needed information
does not appear in this document, the
5ESS switch core documentation provided on
CD-ROM may be examined. The primary usage of the CD-ROM documentation by
DRM personnel will most likely be for ASM information or for referencing the
235-600-700,
Input Messages Manual and the 235-600-750, Output Messages Manual .
