INTRODUCTION
This document is intended to be used as a quick reference for the
following systems:
●
●
DEFINITY Communications System Generic 1 (multi-carrier
cabinet)
DEFINITY Communications System Generic 1 (single-carrier
cabinet)
●
System 75 (V1, V2, and V3)
●
System 75 XE (XEV2 and XEV3).
The DEFINITY Generic 1 (G1) multi-carrier cabinet
compares to System 75 and the DEFINITY Generic 1 (G1)
single-carrier cabinet compares to System 75 XE.
Information in this document applies to all versions and types of
the listed systems unless specifically noted otherwise i n
parentheses.
G1 shown in parentheses in the remainder of this document
(except in the System Parameters table) refers to both the
DEFINITY Communications System Generic 1 multi-carrier
cabinet (MCC) and single-carrier cabinet (SCC) systems unless
otherwise noted.
This issue replaces all previous issues of this document. The
reason for reissue is to add additional information on DEFINITY
Communications System Generic 1, to provide Duplication
Option information, to clarify power requirements, to update the
system parameters table, and to make minor revisions.
Information that applies to Generic 1 only is noted by showing
(G1) throughout the document.

FEDERAL COMMUNICATIONS COMMISSION
(FCC) INFORMATION
The system FCC registration number is AS593M-13283-MF-E. The ringer
equivalent is 0.5 ampere.
DUPLICATION OPTION
The Duplication Option provides:
●
A duplicated control carrier (multi-carrier cabinet) or a duplicated
control cabinet (single-carrier cabinet) that houses a second Switch
Processing Element (SPE). The SPE includes the following:
— Processor Circuit Pack TN773
— Network Control Circuit Pack TN777
— Memory Circuit Pack(s) TN770.
●
●
●
●
●
Power source to the fans from both the control carrier and duplicated
control carrier.
A tape drive circuit pack TN774 in both control carriers.
Duplicated Tone-Clock circuit packs TN768 that allow the system
clock to be generated from either tone-clock circuit pack.
Duplicated fiber optic cable between the Processor Port Network
(PPN) cabinet and the Expansion Port Network (EPN) cabinet.
Duplicated 4-type lightwave transceivers at both the PPN and EPN
cabinets to terminate the fiber optic links.

The ISDN PRI sends digitized voice and digital data in T1
frames at a 1.544 Mbps rate. Each frame consists of twenty-four 64
kbps channels plus 8 kbps for framing. This represents 23 Bearer
(or B) channels plus 1 Data (or D) channel. The maximum user
rate is 64 kbps for voice and data.
