1. OVERVIEW: SYSTEM 85 AND DEFINITY GENERIC 2
WITH TRADITIONAL MODULES
AT&T System 85 and DEFINITY® Generic 2 Communications System (hereafter abbreviated to
DEFINITY Generic 2 or Generic 2) with traditional modules are communications systems with
multimodule architecture that provide integrated voice and data switching via a state-of-the-art
communications processor (called the common control or CC), a time-multiplexed switch (TMS), and
the communications modules. A single System 85 or DEFINlTY Generic 2 with traditional module
capability can contain up to 31 modules with each module providing as many as 1536 analog ports. The
multimodule architecure uses the TMS as the link between the modules.
A single System 85 or DEFINIIY Generic 2 with traditional modules can support from 300 to 32,000
lines. When a System 85 or DEFINITY Generic 2 with taditional modules is linked in a distributed
communications system (DCS) — a network of switches such as other System 85s, DEFINITY Generic
2 with traditional modules, AT&T DIMENSION® PBXs with FP8-3, and AT&T System 75s — the
DCS is capable of supporting up to 100,000 lines.
This chapter presents an overview of the components of System 85 and DEFINITY Generic 2 with
traditional modules that are major factors in the design of a wiring installation. For more comprehensive
information on System 85, see the System 85 System Description Reference Manual (555-103-201). For
more details on DEFINITY Generic 2s with traditional modules, see the DEFINITY™ Communications
System Generic 2 and System 85 System Description Reference Manual (555-104-201). See the
DEFINITY Generic 2 with Traditional Module section at the end of this chapter for a brief list of
features supported only by DEFINITY Generic 2 with traditional modules.
MAJOR COMPONENTS FOR SYSTEM 85 AND DEFINITY GENERIC 2 WITH TRADITIONAL
MODULES
A System 85 or DEFINITY Generic 2 with traditional module consists of four major operating units: the
common control (CC), the module control (MC), the ports, and the TMS.
A System 85 or DEFINITY Generic 2 with traditional module requires from 2 cabinets for a single-
module system to as many as 128 cabinets for a multimodule system with the maximum number of
lines. When a System 85 or DEFINITY Generic 2 with traditional modules is housed in 2 cabinets, it
does not require the TMS function; the MC and port units are combined in 1 cabinet.
CC
The CC is the communications processor, or master controller; it contains a group of components that
control, supervise, and coordinate system operations.
