PART 1. SYSTEM OVERVIEW

1.1 GENERAL DESCRIPTION

The SAMSUNG iDCS 500 (Digital Communications System) 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 employs DSP (Digi-
tal Signal Processors) digital technology.
The iDCS 500 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 and add-on modules. Mis-
cellaneous circuits are provided to allow such optional features as external paging, mu-
sic 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 iDCS 500 system is both economical and easy. Begin with a single cabi-
net configured as a basic Key Service Unit and then add up to two more cabinets as your
business grows. Its low and medium density 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 iDCS 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 maxi-
mum 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 power supply
unit (either PSU60 or PSU-B) the cabinet can support up to 120 station devices. Both
power supply 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.
