							INTRODUCTION
INTRODUCTION
The Pocket Reference is intended to be used as a quick reference
for the following systems:
l
lDEFINITY® Communications System Generic 3i/r
Version 2 (multicarrier cabinet)
DEFINITY Communications System Generic 3s/vs/i/r
Version 2 (single-carrier cabinet)
Note:This document is intended for an audience that is
familiar with the systems discussed. Consequently, it
employs many abbreviations for commonly used
terms.
The DEFINITY Generic 3rV2 (G3rV2) Processor Port Network
(PPN) can only be housed in a multicarrier cabinet (MCC).
DEFINITY Generic 3r Expansion Port Networks (EPNs) can be
housed in MCCs or single-carrier cabinets (SCCs).
The DEFINITY Generic 3sV2 and 3vsV2 (G3sV2 and G3vsV2)
systems can only be housed in a single-carrier cabinet (MCC).
Information in this document applies to all versions and types of the
listed systems unless specifically noted otherwise in
parentheses. GsV2, G3vsV2, G3iV2, or G3rV2 shown in
parentheses in the remainder of this document (except in table
headings) refers to both the DEFINITY Communications System
multicarrier cabinet (MCC) and single-carrier cabinet (SCC) sys-
tems for the specified version, unless otherwise noted.
This issue replaces all previous issues of this document. The rea-
son for reissue is to cover Version 2 enhancements to the DEFIN-
ITY Communications System.

							DESIGN BENEFITS
DESIGN BENEFITS
System management permits user friendly design, implementation,
and administration by the customer
Multiple Port Network—The Processor Port Network (PPN) contain-
ing the system’s control, software, and trunk/terminal circuit
packs and one or up to two (G3iV2) or up to twenty-one
(G3rV2) Expansion Port Network(s) (EPN) containing the inter-
face to the PPN and additional trunk and terminal circuit packs
(the Center Stage Switch is used with the G3rV2 to inter-
connect four or more cabinets)
Two or three (G3iV2 and G3rV2) multicarrier cabinets or three
(G3iV2) single carrier cabinet stacks serving up to 1600
(G3iV2) or 10,000 (G3r) lines and up to 400 (G3iV2) or up to
4000 (G3rV2) trunks
One (G3sV2 or G3vsV2) single carrier cabinet stack serving up to
100 lines or up to 200 trunks
Two (G3iV2) single carrier cabinet stacks serving up to 1200 lines
and 400 trunks (G3rV2 requires a multicarrier cabinet for the
PPN and G3sV2 and G3vsV2 may have a maximum of one
single carrier cabinet stack)
