1.1
PART 1. SYSTEM OVERVIEW
1.1 SIZE AND CONFIGURATION
The DCS 50si is a digital ISDN compatible telephone system designed for small businesses. It can operate with the functionality of a square key system, PABX or a combination of both (hybrid). The DCS 50si employes the very latest DSP (Digital Signal Processor) digital technology.
The DCS 50si 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 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.
CONTENTS
Expanding the DCS 50si system is both economical and easy. Begin with the basic Key
Service Unit and then add an expansion cabinet as your business grows (
1). The KSU has 8 keyset ports and 3 universal card slots that can be used for stations,
trunks or 2x4 combination cards. In addition, the KSU has dedicated slots for a 2SLI card
and a miscellaneous function card. The expansion cabinet adds a further 3 universal slots
and a dedicated slot for a CADENCE CVM8A card. The systems low density card design
allows greater flexibility when configuring a system for the right combination of lines and
stations. A removable memory card (SMEM2 card) makes it convenient to upgrade to
future feature packages as well as providing quick and easy servicing. The maximum
quantities of the various station and trunk types can be seen in the table 1–1.

CONTENTS
1. A maximum of 40 stations can be installed on the system.
2. Only one 2 SLI card can be installed in the system.
3. Only one SMISC card can be installed in the system.
4. Up to six expansion cards can be installed in the system.
5. Only one CADENCE card can be installed in the system.
6. Installing CADENCE reduces the maximum number of stations to 32.
7. Only eight KDbs can be installed in the system and they must be installed on keysets
connected to the (8) eight 2B+D ports on the KSU motherboard.
1.2 TECHNOLOGY
System switching is accomplished by means of a custom IC “engine” that provides 128
switchable digital channels. Each of the 128 digital channels is automatically assigned to
carry voice or data as required by system operation in a PCM format. In addition to the 128
channels mentioned above , the system also utilizes Digital Signal Processors or DSPs.
Each DSP may be configured by the switching control program as a DTMF receiver or a
C.O. tone detector on a per-call basis. The engine chip contains four DSPs and four more
are added when an SMISC 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.
MEMORY
The system operates using stored program control. This program is stored in four EPROM
chips (2048 Kbytes of memory). All specific customer data is stored in non-volatile ran-
1.4
dom access memory (NV-RAM) located on the removable SMEM2 card. 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 50si uses distributed processing. The system’s primary processor is a 16 bit
Motorola® MC68000 operating at a clock speed of 16MHz. The secondary level of processing is done in the keysets.
1.3 PROGRAMMING
The DCS 50si comes with default data. This data provides for operation within seconds
after applying power. All trunks and stations are assigned according to the default numbering plan. This numbering plan is flexible and may be changed if so desired. The technician customizes this default data to meet the end user’s requirements.
The system can be programmed from any display keyset without interrupting normal system operation. There are three levels of programming: TECHNICAL, 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 are controlled
by different security passcodes.
CONTENTS
The DCS 50si 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 uploaded when required to
restore the database.
Through the use of modems, PCMMC can access a DCS 50si 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 on a single DCS circuit card (see Figure 2–4). This optional card is designated
the CVM8A and provides 4 or 8 channels of communication. Only one card is permitted
per system and it is installed in a dedicated slot in the expansion cabinet.
2.3
This fully featured self contained system is connected
directly to the DCS 50si data bus and communicates
with the DCS 50si system processor. This design means
that installation time is minimized, operation is streamlined and many features can be implemented that are
not normally possible with older conventional stand
alone Voice Mail/Auto Attendant systems.
All power to run this self contained system comes from
the DCS 50si telephone system power supply. The DCS
50si power supply is rated according to the number of
stations it will support. When CADENCE is installed it
counts as (8) eight stations of the PSU rating regardless of the number of Voice Processing Modules installed.
