General Description
The Samsung OfficeServ 100 (Digital Communications System) is a digital telephone system
designed for small- to medium-sized businesses. It can operate with the functionality of a key
system, PABX or a combination of both (hybrid). The system employs DSP (Digital Signal
Processor) digital technology.
The OfficeServ 100 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. Three
types of telephone can be connected to the system: proprietary digital phones called “key-
sets” connect to digital line interface cards (DLI), standard telephones (generally called single
line telephones, or SLTs) connect to single line interface cards (SLI), and IP (internet)
phones use the Media Gateway Interface (MGI) card.
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, common audible devices, alarms and
emergency power failure telephones.
Voice Over IP (VoIP)
The OfficeServ 100 system supports calls over an IP network connection using industry-
standard protocols, allowing the transfer of voice, data and images quickly and efficiently.
Samsung Keysets
All keysets have a single PCB with surface-mounted components assuring the highest
product 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.

1-2 Chapter 1
Introduction to the OfficeServ100
Size and Configuration
The OfficeServ 100 comprises a Basic Key Service Unit (KSU, Figure 1–1), Expansion cabi-
net, interface cards and electronic keysets. The simplest KSU has eight (8) keyset ports, but
this is expandable to 18 analogue C.O. line ports, or 24 BRI lines, or 32 stations. In addition,
up to eight keyset daughterboards may be added to the system along with the optional 2SLI
card.
Two types of Expansion cabinet are available: Expansion A and Expansion B. Expansion A
has three universal slots and one dedicated slot for a TEPRI or Voice Mail card. This pro-
vides the maximum configuration of 66 ports with analogue trunk lines or 96 ports with digital
trunk lines. Expansion B has two universal slots and two dedicated slots: the first dedicated
slot is for a Voice Mail card; the second dedicated slot supports a TEPRI card. This provides
the maximum configuration of 66 ports with analogue trunk lines or 96 ports with digital trunk
lines.
The system also has an optional MISC card which provides Music-On-Hold, external paging
and other useful facilities.
NOTE: For a full description of each card discussed in this section, refer to Chapter 2,
Hardware Descriptions.
The charts shown in Figures 1-2 to 1-5 describe possible configurations using the Basic
KSU, Expansion Cabinet and interface cards. However, by using the system’s unique keyset
daughterboards (KDBs), which are installed in the base of a digital keyset, the capacity of the
system can be increased by one station per KDB. Installing a KDB-DLI adds another digital
port while a KDB-SLI adds a single line port. You can mix and match these two types of KDB
to get up to a total of eight KDBs in the system. Using this method allows the system to ex-
pand to a maximum of 64 stations. Adding the optional 2SLI card to the KSU provides a fur-
ther two SLI ports. The combination of the Basic KSU plus three expansion cards in the KSU,
plus three expansion cards and one TEPRI card in the Expansion A cabinet, plus eight
KDBs, plus a 2SLI card provides a maximum configuration of 96 ports plus a MISC card.
Important Points to Remember:
Only one 2SLI card can be installed in the system.
Only one MISC card can be installed in the system.
Only three expansion cards can be installed in the KSU.
An additional three expansion cards and a card such as a TEPRI or SVMi-8 card can be
installed in an Expansion A cabinet; OR an additional two expansion cards and a TEPRI
and Voice Mail card can be installed in an Expansion B cabinet.
A PLL card is required if ISDN cards (TEPRI, BRI) are installed
Only eight KDBs can be installed in the keysets connected to the Basic KSU.
The system can have up to 48 digital keysets, but this is reduced to up to 40 digital key-
sets if an SVMi-8 card or MGI3 card is installed.
The number of stations allowed is reduced by four for each WBS24 installed (up to 16 if
the 4WLI card supports the maximum four base stations).
Large LCD keysets consume three times as much power as other stations.

Introduction to the OfficeServ100
Technology
Memory
All specific customer data is stored in Random Access Memory (RAM) which is protected
against the loss of AC power to the system by an onboard battery back-up system.
The OfficeServ 100 program is stored in 16 Mb NAND flash memory on the Main Control
Processor (MCP1) card. The system boots from a 512 K boot ROM and downloads the op-
erating program into 32 Mb of SDRAM on the MCP1 card. The customer database is stored
in 1 Mb of non-volatile SRAM.
Microprocessors
OfficeServ 100 uses distributed processing. The primary processor is a 32–bit Motorola®
MPC855 on the MCP1 card operating at a clock speed of 50 MHz. Secondary processing is
carried out in some special cards, such as BRI, and also in keysets. Secondary processing
on the base board is done via an MC68EC000 processor running at 16 MHz to provide local
control of cards. Digital keysets use a Hitachi H8 processor for data communication.
Switching
The system provides 256 switchable digital channels. Each of the 256 digital channels is
automatically assigned to carry voice or data as required by system operation in a PCM for-
mat.
In addition to these channels, the system uses Digital Signal Processors (DSPs). Each DSP
may be configured by the switching control program as a DTMF sender, a DTMF receiver or
as a C.O. tone detector on a per–call basis. Four DSP channels are provided by default.
Four additional DSPs are added when a MISC card is installed. This means that the system
contains a total of eight DSP channels when fully expanded. The DSP channels are fully
shared throughout the system as a common resource.
Programming
OfficeServ 100 is a self-configuring system. This means that immediately after applying
power, the system reads the types and locations of all installed interface cards and keysets
and assigns default data to them. All trunks and stations are assigned numbers according to
the default numbering plan. This numbering plan is flexible and may be changed to suit cus-
tomer requirements.
The system can be programmed from any LCD display keyset without interrupting system
operation. There are three levels of programming: technician (or system), customer and sta-
tion. The technician level has access to all programs and can allow the customer access to
system programs as needed. Technician and Customer access levels are controlled by dif-

1-7
ferent security passcodes and access procedures. Refer to the Samsung OfficeServ 100
Programming Guide for more information.
The system also allows the use of a proprietary computer program called OfficeServ Man-
ager. This permits a technician to program the system using a personal computer. OfficeServ
Manager can be used on-site to modify the customer database or to download (save) the en-
tire customer database to a file. This file can then be saved as a backup and be uploaded
when required to restore the database.
Using a modem or Wide Area Network (WAN) connection, OfficeServ Manager can access
the system remotely (off-site) to make changes to the customer database or to perform up-
loads or downloads of the database as if the technician were on-site.
