SYSTEM OVERVIEW

General

The SX-200 DIGITAL PABX is a microprocessor controlled telephone system that
2.1
available in various hardware configurations ranging from 336 to 672 ports, All
configurations of the system are electrically compatible with most
single line telephones,
l
l
key telephone systems,
l
PABX telephone systems, and
l
central office exchanges.
l
The following subsections outline the various hardware configurations and the
of this practice for additional information about the hardware configurations, and to
Section NO TAG for an overview of the software structure. Table 2-1 describes
physical characteristics of the PABX.
Figure 2-1 through Figure 2-5 show the maximum number of trunk and line cards that
each configuration can accommodate.

Hardware Configurations

The SX-200 DIGITAL PABX is available in five different hardware configurations:
2 . 2
480 ports in two cabinets (existing SX-200 DIGITAL PABXs
l
672 ports in two cabinets, and
l
cabinet (SX-200 FD system).
The 336 and 672-par-t configurations use fully digital control circuits, line cards, and
trunk cards. The 456 and 480-port configurations are hybrid systems, using digital
control circuits with a mixture of digital and analog peripheral cards. Customers with
installed SX-200 analog systems may upgrade to the latest in digital switching
technology (456-pat-t) while retaining their investment in cabinets, power supplies, line
cards, and trunk cards.
