PART 1. SYSTEM OVERVIEW
1.1 GENERAL DESCRIPTION
The DCS (Digital Communications System) 400si is a digital telephone system designed
for small to medium-sized businesses. It can operate with the functionality of a square key
system, PABX or a combination of both (hybrid). The DCS 400si employs the very latest
DSP (Digital Signal Processor) technology and utilizes dynamically allocated time slots
providing 384 usable ports.
The DCS 400si offers a variety of interface cards that allow connection to the public tele-
phone network or to private networks. These are generally referred to as trunk cards. Two
types of telephones can be connected to the system. Proprietary digital phones called
“keysets” connect to digital line interface cards (DLI). Standard telephones generally called
“single line sets” connect to single line interface cards (SLI). In addition, DLI station ports
are used to connect peripheral devices such as door phones, serial interface devices and
add-on modules and CTM modules. Miscellaneous circuits are provided to allow such
optional features as external paging, music on hold, background music, common audible
devices, alarms and emergency power failure telephones. Most interface cards can be
inserted or removed with power on to eliminate unnecessary service interruptions while
performing maintenance.
All DCS 400si keysets utilize a single PCB with surface-mounted components assuring
the highest product quality and long life. Samsung’s customary large, easy-to-read dis-
plays and LEDs design make them much easier to use. In many instances, sophisticated
features are made simple through the use of friendly display prompts or push-on/push-off
feature keys.
Expanding the 400si system is both economical and easy. Stack the expansion cabinet on
top of the main cabinet to double the size of the system. A Removable Customer Module
(DCDM) and a Removable ROM Module make it convenient to upgrade to future feature
packages.
1.2 SIZE AND CONFIGURATION
The DCS 400si is a fully modular system comprised of a main cabinet and one additional
expansion cabinet, interface cards and electronic keysets. Each cabinet has 10 universal
card slots providing 192 ports. A fully expanded system has 384 universal ports capable
of supporting various combinations of stations and trunks. The DCS 400si cabinets are
identical in construction and have a passive backplane with all active circuitry located on
the plug-in circuit boards. This means that any enhancements to the system are done on
the cards and do not require replacement of the cabinet(s).
