CHAPTER 1System Overview
1.1 Introduction
DCS Compact II, Digital Communication 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).
DCS Compact II employs the very latest DSP technology (Digital Signal
Processors).
DCS Compact II offers a variety of interface cards that allow connection to the
public telephone network or private networks. These are generally referred to as
trunk cards. Two types of telephones can be connected to the systems. Proprietary
digital phones called "Keysets" connect to digital line interface cards (DLI).
Standard telephone sets generally called "single line telephones"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 provided to allow such optional features as external paging, music on
hold, background music, common audible devices, alarms and emergency power
failure telephones.
All DCS 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.
NOTES
1. 'DCS' is the general term used in the text to refer to all systems. Any differences
between the systems are indicated under separate headings ‘DCS Compact II’
'DCS COMPACT' and 'DCS'.
2. It is not possible to expand from DCS Compact II to a DCS system nor to
expand from DCS Compact to DCS Compact II.

1.2 Size and Configuration
The DCS Compact II system consists of the basic Key Service Unit, an Expansion
cabinet and Interface cards and Digital keysets. The Key Service Unit begins with
eight (8) keyset ports expandable to 18 analogue C.O. line ports, or 24lines if 4
BRI cards are used, or 32 stations. In addition, up to 8keyset daughter boards
may be added to the system along with the optional 2 SLI card.
The Expansion cabinet has three Universal slots and one DCS slot for PRI or VM
service, which provides the maximum configuration of 66 ports with analogue
trunk lines or 88 ports with Digital trunk lines.
Two types of telephones can be connected to the system: proprietary digital
stations called "keysets" that connect to DLI (Digital Line Interface) ports and
standard telephone sets, generally called "single line telephones", that connect to
SLI (Single Line Interface) ports.
The system also has an optional Miscellaneous card which provides Music on
Hold facilities,two serial I/O ports and other useful facilities.
The following charts (Figures 1–1 and 1–2) describe configurations using the
basic Key Service Unit (KSU), an Expansion cabinet and expansion cards.
However, by using the DCS's unique keyset daughter boards (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. Mix and match these two types of KDb to get up
to a total of 8KDbs in the system. Using this method allows the DCS Compact II
to expand to a maximum of 64 stations. Adding the optional 2 SLI card to the
KSU provides a further two SLI ports. The combination of the basic 008 KSU plus
three expansion cards in the KSU plus three expansion cards and one DCS card in
the Expansion cabinet plus 8KDbs plus a 2 SLI card provides a maximum
configuration of 88 ports plus Miscellaneous card.
Configuration Notes
1. Only one 2 SLI card can be installed in the system.
2. Only one Miscellaneous card can be installed in the system.
3. Only three expansion cards can be installed in the Key Service Unit and the
additional three expansion cards and a DCS card like as PRI can be installed in
the Expansion cabinet.
4. Only 8KDbs can be installed in the keysets connected to the 008 Basic KSU.
5. If a PRI card is installed in the DCS card slot, the last expansion slot of the
Expansion cabinet should remain blank.

1.3 Technology
Switching
System switching is accomplished by means of a custom IC "engine" that
provides 256 switchable digital channels. The engine is controlled by its own
16–bit MotorolaMC 68000 microprocessor and switching control program.
Each of the 256 digital channels is automatically assigned to carry voice or data
as required by system operation in a PCM format.
In addition to the 256 channels mentioned above, the systems also utilize 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. Each engine chip contains 4DSP channels.
Four additional DSPs are added when a MISC card is installed. This means that
the system contains a total of 8DSP channels when fully expanded. The DSP
channels are fully shared throughout the system as a common resource.
Memory
The systems operate using stored program control. This program is stored in
EPROM chips. 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 on–
board battery backup system.
Microprocessors
DCS Compact II uses distributed processing. The primary processor of the
system is a 16–bit MotorolaMC68000 operating at a clock speed of 16 MHz.
Secondary processing is in the some special cards like as BRI and also done in
the keysets. The digital keyset uses a Hitachi H8 processor for data
communication within the DCS Compact II.

DCS Compact II General Description Chapter 1. System Overview

1.4 Programming
DCS Compact II is self–configuring. This means that when the power is switched
ON, the system reads the types and locations of all installed cards and telephones
and assigns default data to them. This data provides for system operation within
seconds after power is switched ON. All trunks and stations are assigned
according to the default numbering plan. This numbering plan is flexible and
may be changed to suit customer requirements. The installing technician
customizes this default data to meet the end user's requirements.
The systems can be programmed from any LCD display keyset without
interrupting system operation. There are three levels of programming:
technician, customer and station. The technician level has access to all programs
and can allow the customer access to system programs as needed. The
technician and customer access are controlled by different security passcodes
and access procedures.
DCS Compact II also allows the use of a proprietary computer program called
PCMMC. This permits a technician to program the system using a personal
computer. PCMMC can be used on–site to modify the customer database or to
download (save) the entire customer database to a file. This file can then be
saved as a backup and be uploaded when required to restore the database.
Through the use of modems, PCMMC can access a DCS Compact II system
remotely (off–site) to make database changes or perform uploads or downloads
of the customer database as if the technician were on–site.
