PART 1. SYSTEM OVERVIEW

1.1 GENERAL DESCRIPTION

The SAMSUNG OfficeServ 500 (Digital Communications System) is a VoIP enabled 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 employs DSP (Digital Signal Processors) digital technology. With inte-
grated Media Gateway Cards (MGI), local IP keysets, remote IP keysets and IP networking are easily and econom-
ically added as needed.
The OfficeServ 500 offers a variety of interface cards that allow connection to the public telephone 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) or connect to an
Ethernet LAN and communicate with the system through the Media Gateway Interface cards (MGI). Standard tele-
phones 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 and add-on modules. Miscellaneous circuits are pro-
vided to allow such optional features as external paging, music on hold, background music, and common audible
devices. All interface cards are encased in an anti-static plastic enclosure and most can be inserted or removed
with power on to eliminate unnecessary service interruptions while performing maintenance.
All keysets utilize a single PCB with surface-mounted components assuring the highest product quality and long
life. Samsung's customary large, easy-to-read displays and LEDs in the button 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 OfficeServ 500 system is both economical and easy. Begin with a single cabinet configured as a
basic Key Service Unit and then add up to two more cabinets as your business grows. Its low and medium densi-
ty card design allows greater flexibility when configuring a system for the right combination of lines and stations.
A removable software cartridge (SmartMedia card) makes it convenient to upgrade to future feature packages.

1.2 SIZE AND CONFIGURATION

The OfficeServ 500 is a fully modular system comprised of a single cabinet configured as a Key Service Unit, up to
two additional cabinets, interface cards and electronic keysets. A fully expanded system using the T1/PRI cards
can have a maximum of 352 lines or 360 stations. Without the T1/PRI cards, the maximum number of lines is 208
and the maximum number of stations is 360.The maximum number of ports supported by the system is 488. Each
cabinet of the system supports two power supply units, the first of which must be a PSU-B and can support up to
56 stations. When assisted by a second PSU-B the cabinet can support up to 120 station devices. Both power sup-
ply units are connected to the DC bus for external battery backup. Each cabinet also has four (4) Digital Signal
Processor (DSP) channels for use as DTMF receivers or tone detectors.
SINGLE CABINET SYSTEM
A single cabinet system has eight universal interface card slots, a
dual purpose interface card / signal processor card, a main processor
card slot, and two power supply slots, the first of which must be
occupied by a PSU-B (see Figure 1–1). If "M" version software is used
then nine slots can be used for interface cards. If "L" version software
is used then eight interface cards can be installed and an SCP2 card
must be installed in the dual purpose slot. Station or trunk (Line)
cards can be installed in any interface card slot. TEPRI/TEPRIa cards
must be installed in slots 1, 2 or 3.This allows a maximum of 120 sta-
tions or 120 lines with T1's being used or 72 lines without T1's.
