Terminology
The Samsung OfficeServ500 digital telephone system is designed for medium-sized busi-
nesses. The system is configured as an ‘S’, ‘M’ or ‘L’ system: ‘S’ and ‘M’ systems are single
cabinet systems while ‘L’ systems have a higher capacity and can be expanded to two or
three cabinets. It is possible to easily upgrade from an ‘M’ to an ‘L’ system by changing the
software. All systems are controlled by a main control processor card, the MCP2.
General Description
All systems can operate with the functionality of a square key system, PABX or a combina-
tion of both (hybrid). They employ DSP (Digital Signal Processors) digital technology.
A variety of interface cards are available that allow connection to the public telephone net-
work or to private networks. These are generally referred to as trunk cards. Three types of
telephone can be connected to the system: proprietary digital phones (keysets) which con-
nect to digital line interface cards (DLI); standard telephones (generally called single line tele-
phones, or SLTs) which connect to single line interface cards (SLI); and Internet (IP) phones.
In addition, DLI station ports are used to connect peripheral devices such as door phones
and add-on modules. Miscellaneous circuits are provided to allow such optional features as
external paging, music-on-hold, background music, and common audible devices. All inter-
face cards are encased in an anti-static plastic enclosure and some can be inserted or re-
moved with power on to eliminate unnecessary service interruptions while performing main-
tenance.
All keysets have a single PCB with surface-mounted components assuring the highest prod-
uct quality and long life. Samsung’s customary large, easy-to-read displays and key LEDs
make them much easier to use. In many instances, sophisticated features are made simple
through the use of friendly display prompts or programmable feature keys.
Expanding the system is both economical and easy. You can begin with a single cabinet con-
figured as a basic Key Service Unit (KSU) and then add up to two more cabinets as your
business grows. Its low- and medium-density card design allows greater flexibility when con-
figuring a system for the right combination of lines and stations. A removable software car-
tridge (SmartMedia card) makes it convenient to upgrade to future feature packages.
