Overview: Definity Generic 2 With Universal Modules; Major Components-Multicarrier Module - Avaya 6424D+M User Manual

6. OVERVIEW: DEFINITY GENERIC 2 WITH UNIVERSAL MODULES

This chapter identifies the important differences between a DEFINITY® Generic 2 Communications
System (hereafter abbreviated to DEFINITY Generic 2 or Generic 2) with universal modules and the
systems described in chapter 1, Overview: System 85 and DEFINITY Generic 2 with Traditional
Modules. A brief description of the major components of the single carrier module (SCM), a type of
remote universal module that introduces new cabinetry, is included toward the end of this chapter.
Generally, the configurations and system design rules that apply to universal modules also apply to
SCMs. Significant information on the SCM will be included throughout the universal module chapters
of this document, as needed.
MAJOR COMPONENTS—MULTICARRIER
Generic 2's main operating units are the common control (CC) carrier, time-multiplexed switch (TMS),
common port carrier (CPC), and universal module control (UMC) carrier. These operating units are
contained in either the CC/TMS cabinet, UMC cabinet, or TMS cabinet.
A DEFINITY Generic 2 with universal modules offers multimodule capability. A single system can
contain up to 31 communications switching modules with each module providing as many as 1440 ports
for a universal module. The multimodule architecture uses a time-multiplexed switch (TMS) as the link
between communications switching modules.
Cabinet Types
The Generic 2 system has three types of cabinets: the CC/TMS, TMS, and UMC. The CC carrier
(J58888AB) and TMS carrier (J58888C) are housed in the new CC/TMS cabinet together; both the port
carriers and UMC carriers are housed in the new UMC cabinets. The TMS carrier is housed in a TMS
cabinet in duplicated systems with more than seven modules or unduplicated systems with more than 15
modules. The CC/TMS cabinet can support up to 15 modules in an unduplicated system or seven
modules in a duplicated system.
The UMC cabinet is the most significant hardware introduction in the Generic 2 release, providing new
port board technology that saves on power, cabinetry, and space. The UMC cabinet houses the UMC
carriers (J58890-AK1) and CPCs (J58890BB) in a single cabinet. The port boards used with the UMC
carriers are System 75 boards; they are denser than System 85 boards, requiring less space in the
equipment room.
DEFINITY Generic 2 offers some features that require the use of R2V4 technology. These features
require a traditional switching module and are listed in chapter 1, Overview: System 85 and DEFINITY
Generic 2 with Traditional Modules.
