PART 1. SYSTEM OVERVIEW
1.1 GENERAL DESCRIPTION
The SAMSUNG DCS (Digital Communications System) is a digital telephone system de-
signed 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 the very
latest DSP (Digital Signal Processors) digital technology.
The DCS 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). 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, serial interface devices 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 interface cards are encased in an anti-static
plastic enclosure and can be inserted or removed with power on to eliminate unnecessary
service interruptions while performing maintenance.
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.
Expanding the SAMSUNG DCS system is both economical and easy. Begin with the basic
Key Service Unit and then add up to two expansion cabinets as your business grows. Its
low density card design allows greater flexibility when configuring a system for the right
combination of lines and stations. A removable software cartridge (ROM card) makes it
convenient to upgrade to future feature packages.
1.2 SIZE AND CONFIGURATION WITH PSU 40
The DCS is a fully modular system comprised of a basic Key Service Unit, two additional
expansion cabinets, interface cards and electronic keysets. A fully expanded system us-
ing the T1 card can have a maximum of 168 lines or 112 stations. Without the T1 card, the
maximum number of lines is 160 and the maximum number of stations is 120.
SINGLE CABINET SYSTEM
A single cabinet system has seven universal card slots (see Figure 1–1). Station or trunk
(line) cards can be installed in any of these slots. The T1 card must be installed in slot 1,
3 or 5 and the even-numbered slot to the right of the T1 card must be left empty. This card
requires two slots as it provides 24 lines. This allows a maximum of 40 stations of any kind

1–3
or 64 lines in a single cabinet system. With- 
out the T1 card, the maximum number of lines
in the basic KSU is 56.
TWO CABINET SYSTEM
When it is required that the basic system be
expanded to provide a capacity greater than
that described above, the Expansion A or A1
card must be installed in slot seven of the
KSU. This card provides the High-Speed Digi-
tal Link (HDL) pathways that are used to con-
nect the expansion cabinets to the basic KSU.
Adding this card therefore reduces the num-
ber of universal card slots in the basic KSU
to six. 
Adding one expansion cabinet makes the 
system a two cabinet system with 13 univer-
sal card slots (see Figure 1–2). This allows a
maximum of 80 stations or 112 lines when
using a T1 card. Without the T1 card, the
maximum number of lines is 104 while the
maximum number of stations remains at 80.

THREE CABINET SYSTEM
In a fully expanded three cabinet system, there are 20 universal card sl\
ots (see Figure 1 –3).
This allows a maximum of 112 stations or 168 lines when using a T1 card. Without the T1 card, 
the maximum number of lines is 160 and the maximum number of stations is\
 120.
1.3 SIZE AND CONFIGURATION WITH PSU 60
The PROSTAR DCS is a fully modular system comprised of a basic Key Service Unit, \
two
additional expansion cabinets, interface cards and electronic keysets. A\
 fully expanded
system using the T1 card can have a maximum of 168 lines or 172 stations\
. Without the
T1 card, the maximum number of lines is reduced to 160.
SINGLE CABINET SYSTEM
A single cabinet system has seven universal card slots (see Figure 1 –1). Station or trunk
(line) cards can be installed in any of these slots. The T1 card must \
be in slot 1, 3 or 5 and
the even-numbered slot to the right of the T1 card must be left empty. This card requires
two slots as it provides 24 lines. This allows a maximum of 60 stations \
of any kind or 64
lines in a single cabinet system. Without the T1 card, the maximum numbe\
r of lines in the
basic KSU is reduced to 56.
TWO CABINET SYSTEM
When it is required that the basic system be expanded to provide a capac\
ity greater than
that described above, the Expansion A or A1 card must be installed in sl\
ot seven of the
KSU. This card provides the High-Speed Digital Link (HDL) pathways tha\
t are used to
connect the expansion cabinets to the basic KSU. Adding this card will t\
herefore reduce
the number of universal card slots in the basic KSU to six.

Adding one expansion cabinet makes this a two cabinet system with 13 universal card
slots (see 
Figure 1–2). This allows a maximum of 116 stations or 112 lines when using a
T1 card. Without the T1 card, the maximum number of lines is reduced to 104.
THREE CABINET SYSTEM
In a fully expanded three cabinet system, there are 20 universal card slots (see Figure 1–3).
This allows a maximum of 172 stations or 168 lines when using a T1 card. Without the T1
card, the maximum number of lines is reduced to 160.
1.4 TECHNOLOGY
SWITCHING
System switching is accomplished by means of a custom IC “engine” that provides 256 swit-
chable digital channels. The engine is controlled by its own 16 bit Motorola MC 68000 micro-
processor 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, the system also utilizes 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
four DSP channels. Single engine chips are located on the KSU and EKSU motherboards
with a pair of engine chips located on the Expansion A and Expansion A1 cards. This
means that the system contains a total of 20 DSP channels when fully expanded. The
DSP channels are fully shared throughout the system as a common resource.
MEMORY
The system operates using stored program control. This program is stored in two EPROM
chips (ROM) totaling 1024 kilobytes of memory. However, if the system is configured for
operation with Caller ID, the program size is 2048 kilobytes contained in four EPROMs. All
specific customer data is stored in 512 kilobytes of non-volatile random access memory
(NV-RAM) on the main KSU motherboard. It is protected by a super capacitor providing
seven days of memory protection in the event of loss of AC power to the system.
MICROPROCESSORS
The DCS uses distributed processing. Its primary processor is a 16 bit Motorola MC68000
operating at a clock speed of 8 MHz. The secondary level of processing is on the cabinet
motherboard. This is another MC68000 processor and provides local control of the 256
PCM channels via the engine chip. The tertiary level of processing is done in the keysets.
The digital keysets use a Hitachi H8 processor for data communication within the DCS.
1.5 PROGRAMMING
The DCS is a self-configuring system. This means that immediately after applying power,
the DCS reads the types and locations of all installed cards and telephones and assigns
default data to them. This data provides for system operation within a minute after apply-
