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 (Digital Signal Processors) digital
technology.
The iDCS 500 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, 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 cabinet 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 Chapter 1
Introduction To System
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 TEPRI cards can have a maximum of 352 lines or 360 stations. Without the TEPRI cards, the
maximum number of lines is 208 and the maximum 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.
Single Cabinet System
A single cabinet system has nine universal card slots, a processor slot and two power supply slots, the
first of which must be occupied by a PSU-B (see Figure 1–1). Station or trunk (line) cards can be
installed in any of the nine universal slots. The TEPRI cards must be installed in slots 1, 2 or 3. This
allows a maximum of 120 stations of any kind or 120 lines in a single cabinet system. Without using
TEPRI cards, the maximum number of CO lines in the basic KSU is 72.
Figure 1–1 iDCS Single Cabinet System
NOTE: The first power supply slot must be occupied by a PSU-B to supply sufficient power to all 10
slots (9 universal and a processor slot) and support up to 56 stations. The second power supply slot
can be occupied by either a PSU60 or PSU-B. Do not use a PSU40 in either PSU slot.

1-3
Two Cabinet System
When it is required that the basic system be expanded to provide a capacity greater than that
described above, the Signal Control Processor (SCP) card must be installed in slot nine of the first
cabinet. This card provides an intermediate level of processing to control the first cabinet therefore
freeing resources on the Main Control Processor (MCP) to control the entire system. Adding the SCP
card therefore reduces the number of universal card slots in the first cabinet to eight. In addition, the
MCP card must be equipped with a ESM daughter board and a IPM daughter board. Only a LAN
daughter board may optionally occupy the remaining daughter board position on the MCP card. All
other types of daughter boards must be installed on the SCP card or LCP card.
Adding one expansion cabinet makes the system a two cabinet system with 17 universal card slots
(see Figure 1–2). This allows a maximum of 240 stations or 232 lines when using TEPRI cards.
Without the TEPRI cards, the maximum number of lines is 136 while the maximum number of stations
remains at 240. This second cabinet is controlled by a Local Control Processor (LCP) in a similar
manner to the SCP in the first cabinet and connects to the MCP via a 25 pair cable. The LCP
processor card resides in a dedicated slot 10 of the second cabinet and therefore does not deplete the
number of universal card slots.
NOTE: The first power supply slot in each cabinet must be occupied by a PSU-B to supply sufficient
power to all 10 slots (9 universal and a processor slot) and support up to 56 stations. The second
power supply slot can be occupied by either a PSU60 or PSU-B. Do not use a PSU40 in either PSU
slot.
Figure 1–2 iDCS Two Cabinet System

1-4 Chapter 1
Introduction To System
Three Cabinet System
In a fully expanded three cabinet system, there are 26 universal card slots (see Figure 1–3). This
allows a maximum of 360 stations or 352 lines when using TEPRI cards. Without TEPRI cards, the
maximum number of lines is 208 and the maximum number of stations is 360. The third cabinet is
also controlled by a Local Control Processor (LCP) in a similar manner to the LCP in the second
cabinet and connects to the second cabinets’ LCP via a 25 pair cable. This processor resides in a
dedicated slot 10 and therefore does not deplete the number of universal card slots. In addition, the
MCP card must be equipped with a ESM daughter board and a IPM daughter board. Only a LAN
daughter board may optionally occupy the remaining daughter board position on the MCP card. All
other types of daughter board must be installed on the SCP card or LCP card.
Figure 1–3 iDCS Three Cabinet System
NOTE: The first power supply slot in each cabinet must be occupied by a PSU-B to supply sufficient
power to all 10 slots (9 universal and a processor slot) and support up to 56 stations. The second
power supply slot can be occupied by either a PSU60 or PSU-B. Do not use a PSU40 in either PSU
slot.

TECHNOLOGY
Memory
The system operates using stored program control. This program is stored on a SmartMedia card
inserted into the Main Control Processor card (MCP) and contains a minimum of eight Megabytes of
NAND-Flash memory. Optional, larger capacity, SmartMedia cards are also available to provide a
backup customer database and a backup operating program. The system boots from a 256 Kbyte
boot ROM and downloads the operating program into four megabytes of DRAM on the Main Control
Processor (MCP) card. The four megabytes of DRAM are increased to 8 megabytes with the addition
of the Inter Processor communications Module (IPM) in an expanded system. The customer
database is stored in 1.0 Mbytes of non-volatile SRAM for a single cabinet system. This expands to
2.5 Mbytes with the IPM installed and to 3.0 Mbytes with the addition of the optional LAN interface
module (LAN).
Microprocessors
The iDCS 500 uses distributed processing. Its primary processor is a 16 bit (32 bit core) Motorola
MC68302 operating at a clock speed of 25 MHz on the MCP card. This provides all the processing
necessary for a single cabinet system. In a multi cabinet system the secondary level of processing is
on the SCP card for the first cabinet and on the LCP cards for the expansion cabinets. These
secondary processors are MC68302 processors running at 16 MHz and provide local control of each
cabinet. Messaging between the primary and secondary processors is handled by a MC68302
processor running at 25 MHz located on the Inter Processor communications Module (IPM) PCB.
The tertiary level of processing is done in the keysets. The digital keysets use a Hitachi H8 processor
for data communication within the system.

1-6 Chapter 1
Introduction To System
PROGRAMMING
The iDCS 500 is a self-configuring system. This means that immediately after applying power, the
iDCS 500 reads the types and locations of all installed interface cards and keysets and assigns default
data to them. This data provides for system operation within a few minutes after applying power.
All trunks and stations are assigned three or four digit numbers according to the settings of the
switches on the MCP card and the default numbering LAN. This numbering LAN 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 system 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. Technician
and customer access levels are controlled by a different security passcodes and access procedure.
The iDCS 500 also allows the use of a proprietary computer program called DPAP-PCMMC. This
permits a technician to program the system using a personal computer. DPAP-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, DPAP-PCMMC can access the iDCS 500 system remotely (off-site) to
make database changes or perform uploads or downloads of the customer database as if the
technician were on-site.

SYSTEM CABINETS
The cabinets that make up the iDCS 500 system are of metal construction and may be utilized as either
as an expansion cabinet or as a main cabinet / key service unit (KSU). The cabinets may be used
singly or may be stacked up to three (3) high to achieve maximum capacity. A single cabinet may be
wall mounted for smaller applications or alternatively the system may be mounted in a standard
nineteen inch (19”) equipment rack after removal of the side panels and their supporting brackets.
Each cabinet is comprised of the following:
yEight interface card slots
yOne dual purpose interface card / signal processor slot (see ‘Size and Configuration’ section.)
yOne processor card slot
yTwo power supply slots
yOne IOM board slot for use when the cabinet is the main cabinet/KSU (see ‘IOM Board’ section)
yAC power connector
yDC power (Battery Backup) connector
NOTE: The first power supply slot must be occupied by a PSU-B power supply to supply sufficient
power to all 10 slots (8 interface, one dual purpose and one processor slot). The second power
supply slot can be occupied by either a PSU 60 or a PSU-B. Do not install a PSU 40 in any PSU slot.

Hardware Descriptions
COMMON CONTROL CARDS
PROCESSOR CARDS
The iDCS 500 requires a processor card or cards in order to operate. In a single cabinet iDCS 500
system, only one processor card, the Main Control Processor (MCP), is required. When the system is
expanded to two or three cabinets a second, Signal Control Processor (SCP), is required for the main
cabinet to assist the MCP and each expansion cabinet requires its own Local Control Processor (LCP).
These processor cards are described below.
Main Control Processor (MCP)
The Main Control Processor (MCP) is installed in a dedicated processor slot, slot 10, of the first cabinet
and has positions for three daughter boards. The first daughter board (LOC1) can support one of
four types of daughter board, a Multi-Frequency Module (MFM), a Switch/Conference Module (SCM),
an R2/CID Module (RCM), in a single cabinet system and is required to support the Expanded
Switching Module (ESM) in a multiple cabinet system. The second daughter board position (LOC2)
can support the MFM, the SCM, the RCM or the Local Area Network (LAN) board in a single cabinet
system. This position is also required to support the Inter Processor communications and Memory
(IPM) daughter board in a multiple cabinet system or a system running the L version software. The
third daughter board (LOC3) can support a Miscellaneous (MISC) daughter board or a Local Area
Network (LAN) daughter board in a single cabinet system or a LAN daughter board in a multiple
cabinet system.
MAIN CONTROL PROCESSOR (MCP) DAUGHTER BOARD CAPABILITIES
Position Type of Daughter Boards allowed per position
LOC1 MFM, SCM, RCM and ESM*
LOC2 MFM, SCM, RCM, LAN and IPM**
LOC3 MFM, SCM, RCM, LAN and MISC
* The ESM must be installed in this position in a Multiple Cabinet System.
** The IPM must be installed in this position in a Multiple Cabinet System or a Single Cabinet System
running L version software.
NOTE: Only one of any type of daughter board may be installed on any processor card.

2-3
Switch Control Processor (SCP)
The Switch Control Processor (SCP) is installed in slot 9 of the KSU and reduces the available
universal card slots to eight. The SCP card is required when the system is to be expanded beyond a
single cabinet. The SCP card has positions for three optional daughter boards. The first daughter
board position (LOC1) can support one of three types of daughter board, a Multi-Frequency Module
(MFM), a Switch/Conference Module (SCM) or an R2/CID Module (RCM). The second daughter
board position (LOC2) can support the MFM, the SCM, the RCM or the MISC. The third daughter
board position (LOC3) can support one of the three types of daughter board, a Multi-Frequency
Module (MFM), a Switch/Conference Module (SCM) or an R2/CID Module (RCM).

Hardware Descriptions
PROCESSOR CARD DAUGHTER BOARDS
There are seven types of daughter board that fit on the various processor cards. Some daughter
boards will only work on the Main Control Processor (MCP) and the rest will work on any processor
card. The various daughter boards and their uses are described below.
Inter Processor Communications And Memory Module (IPM)
This daughter board installs in position LOC2 of the Main Control Processor and is required to
provide the inter processor messaging channels in a multiple cabinet system. The IPM daughter
board also carries the expanded SRAM and DRAM needed for multiple cabinet systems and single
cabinet systems running L version software.
The IPM daughter board consists of the following:
y1 MC68302 25 MHz Processor (for message handling)
y1.5 megabyte SRAM (for customer database)
y4 megabytes DRAM (for the operating system and scratch pad)
y3 synchronous communications ports (to communicate with the SCP and the LCP’s)
Local Area Network (LAN)
This daughter board installs in either position LOC2 or LOC3 of the Main Control Processor and
provides a 10BASE-T Ethernet LAN connection. In addition to the LAN connection, the LAN board
provides 0.5 megabytes of SRAM to support the increased I/O functions of this card. The LAN
board also provides the hardware to drive the third and fourth Serial I/O ports in the main cabinet
and support for the V90 internal modem.
The LAN daughter board consists of the following:
y10BASE-T LAN Interface
y0.5 Megabytes SRAM (for expanded database functions)
y2 serial I/O ports (maximum asynchronous speed 38.4 Kbps)
Switch And Conference Module (SCM)
The Switch and Conference Module installs on the MCP or the SCM processor cards. In a single
cabinet system the SCM can be installed in LOC1, however in a multiple cabinet system the SCM must
be installed on the SCP as the MCP must have the ESM and IPM daughter boards. The system,
regardless of size can only support one SCM daughter board. Adding a SCM daughter board to the
system increases the number of conference paths in the system from six to twenty four. In addition,
the SCM also adds twelve channels for DTMF and tone detection.
yTwelve (12) channels for DTMF Receiver and tone detection
yEighteen (18) conference paths (for a system total of 24)
