PART 1. SYSTEM OVERVIEW
1.1 GENERAL DESCRIPTION
The DCS (Digital Communications System) 400si 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 400si employs the very latest
DSP (Digital Signal Processor) technology and utilizes dynamically allocated time slots
providing 384 usable ports.
The DCS 400si offers a variety of interface cards that allow connection to the public tele-
phone 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 and CTM 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. Most interface cards can be
inserted or removed with power on to eliminate unnecessary service interruptions while
performing maintenance.
All DCS 400si keysets utilize a single PCB with surface-mounted components assuring
the highest product quality and long life. Samsung’s customary large, easy-to-read dis-
plays and LEDs 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 400si system is both economical and easy. Stack the expansion cabinet on
top of the main cabinet to double the size of the system. A Removable Customer Module
(DCDM) and a Removable ROM Module make it convenient to upgrade to future feature
packages.
1.2 SIZE AND CONFIGURATION
The DCS 400si is a fully modular system comprised of a main cabinet and one additional
expansion cabinet, interface cards and electronic keysets. Each cabinet has 10 universal
card slots providing 192 ports.  A fully expanded system has 384 universal ports capable
of supporting various combinations of stations and trunks. The DCS 400si cabinets are
identical in construction and have a passive backplane with all active circuitry located on
the plug-in circuit boards. This means that any enhancements to the system are done on
the cards and do not require replacement of the cabinet(s).

1.3 TECHNOLOGY
SWITCHING
System switching is accomplished by means of a custom IC “engine” \
that provides 256 
switchable digital channels. When expanded to a two cabinet system the m\
atrix is ex-
panded to 512 digital channels.  The engine is controlled by its own 16 \
bit Motorola MC
68302 microprocessor and switching control program. The 68302 microproce\
ssor is spe-
cifically designed for communication systems. Each of the 512 digital ch\
annels is auto-
matically assigned to carry voice or data as required by system operatio\
n in a PCM for-
mat. 
In addition, the system also utilizes Digital Signal Processors (DSPs)\
. Each DSP may be 
configured by the switching control program as a DTMF receiver or as a C\
.O. tone detec-
tor on a per-call basis. Each engine chip contains four DSP channels. On\
e engine chip is
located on the central processor card.  Additional DSP’s can be easily added using plug-
on daughterboards. This means that a system can contain a total of 68 DS\
P channels
when fully expanded. These 68 DSP channels are fully shared throughout t\
he system as
a common resource. Additionally, 24 dedicated CID DSPs can be added to support the
Caller ID feature. These 24 dedicated DSPs are fully shared throughout t\
he system. Con-
sult your Technical Manual–Installation Section for provisioning details.
MEMORY
The DCS 400si system is a Stored Program Control (SPC) multiprocessor \
system. The
main system program and operating system (OS) are stored in four EPROM\
 (Erasable
Programmable Read Only Memory) chips totaling 2,048 kilobytes of memory\
. These four
EPROMs plug into sockets on the DROMD daughterboard which plugs onto the\
 DCCP
(main processor) board. Please see section 2.6, DROMD Daughterboard, for more de-
tails. 
The customer database and main processor scratch pad memory are containe\
d in 2 Mbytes 
of SRAM (Static Random Access Memory) which is located on the main DCC\
P board. In
case of a power outage the SRAM is protected by an onboard lithium batte\
ry for up to
2,000 hours. 
An optional DCDM (DCS 400si Customer Data Module) daughterboard can be\
 plugged 
onto the DCCP that provides an additional 2 Mbytes of “Super Capacito\
r” backed SRAM
memory. This SRAM memory is an auxiliary customer database storage location th\
at can
be used to store a copy of the customer’s most recent system database. The super ca-
pacitor will maintain the DCDM memory up to 150 hours in case of a power\
 outage. Please
see section 2.6  for more detailed information on the DCDM.
MICROPROCESSORS
The DCS 400si uses distributed processing. Its primary (CCP) processor\
 is a 16 bit Motorola
MC68302 operating at a clock speed of 16 MHz. This processor provides lo\
cal control of
the 256 PCM channels in a single cabinet system. In an expanded system, \
an additional

1.5
processor (ECP) is coupled with the primary processor expanding the system to 512 PCM
channels. Secondary processors are located on station and trunk cards. The tertiary level
of processing is done in the keysets. The digital keysets use a Hitachi H8 processor for
data communication within the DCS 400si.
1.4 PROGRAMMING
The DCS 400si is a self-configuring system. This means that immediately after applying
power, the DCS 400si reads the types and locations of all installed cards and telephones
and assigns default data to them. This data provides for system operation minutes after
applying power. 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 require-
ments.
The system can be programmed from any LCD display keyset without interrupting system
operation. There are three levels of programming: TECHNICIAN, CUSTOMER AND STA-
TION. 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 differ-
ent security passcodes and access procedures. Station programming allows the individual
station user to set various options applicable to their station only. Keyset users have more
options than single line users. Each station user has their own passcode. The Customer
or Technician level programming can also be used to set individual station options.
The DCS 400si also provides for the use of a proprietary windows based computer pro-
gram 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
can be uploaded when required to restore the database.
Through the use of modems, PCMMC can access a DCS 400si system remotely (off-site)
to make database changes or perform uploads or downloads of the customer database
as if the technician were on-site.

2.1 MAIN CABINET
The main cabinet functions in- 
dependently as a stand alone
192 port system or it may be
combined with the expansion
cabinet to make 384 ports.
The cabinet is comprised of a
card cage and a passive back
plane enclosed in a sturdy
metal cabinet that can be wall
mounted or set on casters.
Top, front and side panels can
be easily removed for instal-
lation and servicing. The main cabinet comes with a power distribution b\
oard and AC
power card mounted in the left side. 
The main cabinet provides ten (10) universal card slots. A variety of \
interface cards for 
stations, trunks and miscellaneous functions are installed in these 10 s\
lots. Dedicated
slots are provided for the Common Control Processor (DCCP) and two (2\
) power con-
verter units (see Figure 2–1). 
An optional single line ring generator with message waiting lamp supply \
can be installed in 
the left side of the cabinet. The right side of the cabinet provides spa\
ce for an optional 16
circuit power failure transfer card and functions as a cable channel for\
 25 pair amphenol
cables to the MDF.
2.2 EXPANSION CABINET
The expansion cabinet
mounts directly on top of the
main cabinet and locks in
place to provide a fully ex-
panded 384 port system. The
expansion cabinet is virtually
identical to the main cabinet.
It also has 10 universal slots
and 3 dedicated slots for 2
power supplies and an Expan-
sion Control Processor
(DECP). An optional ring gen-
erator with message waiting lamp supply and 16 circuit power failure tra\
nsfer board can
also be mounted in the expansion cabinet.
