PART 1. SYSTEM OVERVIEW
1.1 INTRODUCTION
DCS-816, Digital Communication System, is a digital telephone system designed for small to
medium-sized businesses. The system employs the very latest Digital Signal Processors (DSP)
technology.
DCS-816 is easy to install and maintain, convenient to use and provides a variety of features,
including advanced features such as ISDN and CTI.
DCS-816 provides some interface cards that allow connection to the public telephone network or
private networks. These are generally referred to as trunk cards. Besides the trunk cards, it
provides some option cards for serial interfaces and the Auto Attendant feature. Two types of
telephones can be connected to the system: proprietary digital phones called "keysets" connect to
digital line interface (DLI) ports; standard telephone sets, generally called "single line telephones,"
connect to single line interface (SLI) ports. In addition, DLI station ports are used to connect
peripheral devices such as door phone interface modules (DPIMs) and CTI interface modules.
Miscellaneous circuits are provided to allow such optional features as external paging, music on
hold, background music, general-purpose dry contact and emergency power failure transfer.
All DCS keysets utilise 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 (key) 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.
NOTE:
1. It is not possible to expand from DCS-816 to other DCS systems (e.g. DCS, DCS Compact).
2. DCS-816 cannot accommodate cards from other Samsung digital systems except for the DCS
Compact BRI card.

Two types of telephones can be connected to the system: proprietary digital stations called
"keysets" that connect to digital line interface (DLI) ports and standard telephone sets, generally
called "single line telephones", that connect to single line interface (SLI) ports.
The Trunk Expansion slot provides an option to select an analogue trunk card or a BRI card.
The DCS-816 system also has some option cards to provide serial I/O ports or AA facilities.
The Basic KSU has two (2) analogue trunk ports and 16 stations, and the trunk expansion slot
provides a maximum capacity of 10 trunk ports and 16 stations.
The system maximum capacity is as follows:
Stations 16 (12 keysets, 4 SLTs)
ISDN channels 8 (4 BRI ports)
Analogue C.O. lines 10
Music channel 1 (Internal or External)
ExternalPage 1
General-purpose Dry Contact 1

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 system also utilises 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. DCS-816 is equipped with
one engine chip containing four (4) DSP channels.
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-816 uses distributed processing. The primary system processor is a 16-bit Motorola
MC68000 operating at a clock speed of 8 MHz. Secondary processing is done in some special
cards, such as BRI, and also in the keysets. The digital keyset uses a Hitachi H8 processor for
data communication within the DCS-816.
1.4 PROGRAMMING
DCS-816 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 customises these
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 (or system), customer and station.
The technician (system) level has access to all programs and can allow the customer access to
system programs as needed. Technician and customer access is controlled by different security
passcodes and access procedures.
DCS-816 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-816 system remotely (off-site) to make
database changes or perform uploads or downloads of the customer database as if the technician
were on-site.

4.2 SYSTEM FEATURE DESCRIPTIONS
Account Code Entry
Station users may enter an account code (maximum 12 digits) before hanging
up from a call. This account code will appear in the last column of the SMDR
printout for that call record. Keyset users may enter this code using an account
(ACCT) key without interrupting a conversation. Single line telephone users
must temporarily interrupt the call by hook–flashing and dialling the feature
access code. Account codes can be up to 12 digits long.
 Forced
When forced, account codes are always verified from a system list of 200
entries. Account codes are always printed on the SMDR report. They can
contain digits 0–9.
 Voluntary
Users may select to enter an account code for any call. Digits can include
0–9, star (*) and #.
All Call Voice Page
Users can page all the internal and all the external paging at the same time by
dialling the All Page code. Keysets may be restricted from making or receiving
pages in system programming.
Attention Tone
To get your attention, a brief tone precedes all page announcements or intercom
voice calls. There are separate programmable duration timers for page and
voice announce tones.
Authorisation Codes
Authorisation codes are used to give permission to make a call. These four digit
authorisation codes can be either forced or voluntary. When used, authorisation
codes will automatically change the dialling station's class of service to the level
assigned to the authorisation code. Authorisation codes may or may not be
programmed to print on SMDR.
 Forced
When a station is programmed for forced authorisation the user must
always enter this code before dialling is allowed. The dialled authorisation
code is verified from a system list of 30 entries.
 Voluntary
Any station user can always enter an authorisation code before they begin
dialling. The dialled authorisation code is verified from a system list of 30
entries.
Auto Attendant
The integrated digital automated attendant option provides four ports per AA
option card. One AA option card per system. Sixteen professionally recorded
prompts inform callers of the progress of their calls. Some examples are: "I am

SAMSUNG General Description
DCS-816 March 1999
4 - 3
sorry. There is no answer", "That station is busy" and "Invalid number. Please try
again". Two minutes of battery–backed random access memory (RAM) provide
up to 48 customer recordings for announcements or greetings. Twelve individual
greeting boxes, each with its own dialling options, allow you to build call routing
branches as needed. Callers are routed through the branches by dialling
extension numbers or single digits.
NOTE
Requires optional hardware and/or software. Ask your dealer for details.
Automatic Hold
While a keyset user is engaged in an outside (C.O.) call, pressing another trunk
key, route key or CALL key automatically places the call on hold when this
feature is enabled. Pressing TRSF, CONFERENCE, PAGE or a DSS key always
automatically places a C.O. call on hold. Intercom calls can be automatically
held only by pressing TRSF or CONFERENCE. Each keyset user can enable or
disable Automatic Hold.
Background Music
Keyset users may choose to hear music through their keyset speakers. Each
user may adjust this level by the use of a volume control program at the selected
keyset.
Branch Groups
Each station can assign its branch group. There are 8 branch groups in DCS-
816. When incoming or intercom call is ringing on station, any other stations that
included the same branch group can answer by lifting the handset or pressing
the speaker or ANS/RLS key.
Call Forwarding
This feature allows the user to redirect (forward) incoming calls. The calls can be
redirected to the attendant, a hunt group, voice mail, external number or another
station user. If the destination station is in Do Not Disturb (DND) mode, the
calling party will receive DND/NO MORE tone. Calls cannot be forwarded to a
door phone.
 All Calls
This type of forwarding is not affected by the condition of the station. All
calls are immediately redirected to the designated destination. If desired,
the destination station may redirect the call back to the forwarded station
by using the transfer feature. The forwarded station user can continue to
originate calls as usual. If no key is programmed as Forward All, the TRSF
key lights steady when a forwarded all condition is set.
 Busy
This feature forwards all calls only when the station set is busy. The station
user can originate calls as usual.
 No Answer
This feature forwards calls that are not answered within a preprogrammed
time. The user can originate calls as usual and receive calls if present. The

SAMSUNG General Description
DCS-816 March 1999
4 - 4
timer is programmable on a per–station basis to allow for differences in
individual work habits.
 Busy/No Answer
This feature allows the station user to use both types of forwarding
