PART 1. SYSTEM OVERVIEW
1.1 SIZE AND CONFIGURATION
The PROSTAR DCS COMPACT is an expandable digital hybrid key telephone system 
that begins with four C.O. line ports and eight keyset ports and expands\
 to ten C.O. line
ports and 22 stations (see Figure 1–1). In addition, up to ten keys\
et daughterboards may
be added to the system to provide the maximum configuration of ten C.O. \
line ports and
32 stations. 
Two types of telephones can be connected to the system: proprietary digit\
al stations called 
“keysets” that connect to DLI (Digital Line Interface) ports and\
 standard telephone sets,
generally called “single line telephones” that connect to SLI (Si\
ngle Line Interface) ports. 
The above chart describes configurations using the basic Key Service Uni\
t and 2 x 4 
expansion cards. However, by using the DCS COMPACT’s unique keyset daughterboards
(KDBs), which are installed in the base of a digital keyset, the capac\
ity of the system can
be increased by one station per KDb. Installing a KDb-DLI adds another d\
igital port while
a KDb-SLI adds a single line port. Mix and match these two types of KDb \
for up to a total
of ten KDBs in the system. Using this method allows the DCS COMPACT to expand to a
maximum of 30 stations. Adding the optional 2 SLI card to the Key Servic\
e Unit provides
a further two SLI ports. The combination of the basic 4 x 8 Key Service \
Unit plus three 2 x
4 expansion cards plus ten KDBs plus a 2 SLI card provides a maximum con\
figuration of
ten C.O. lines and 32 stations plus miscellaneous circuits.

1.2
CONFIGURATION NOTES
1. Only one 2 SLI card can be installed in the system. 
2. Only one MISC card can be installed in the system.
3. Only three 2 x 4 cards can be installed in the system.
4. Only ten KDbs can be installed in the system. 
						

							

1.2 TECHNOLOGY
SWITCHING
System switching is accomplished by means of a custom IC “engine” that provides 256
switchable digital channels. 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 utilizes Digital Signal Processors or DSPs.
Each DSP may be configured by the switching control program as a DTMF sender, a
DTMF receiver or a C.O. tone detector on a per-call basis. The engine chip contains four
DSP channels and an additional four DSPs are added when a MISC 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 either two
EPROM chips (1024 Kbytes of memory) or four EPROM chips (2048 Kbytes of memory)
depending on the feature package. All specific customer data is stored in non-volatile
random access memory (NV-RAM) located on the removable RAM pack. It is protected by
a Ni-Cd (NICAD) battery providing up to 30 days of memory protection.
MICROPROCESSORS
The DCS COMPACT uses distributed processing. The system’s primary processor is a 16
bit Motorola
® MC68000 operating at a clock speed of 8 MHz. The secondary level of
processing is done in the keysets. The digital keyset uses a Hitachi H8 processor for data
communication within the DCS COMPACT.
1.3 PROGRAMMING
The DCS COMPACT comes with default data. This data provides for operation within
seconds after applying power. All trunks and stations are assigned according to the de-
fault 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 sys-
tem 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 are controlled
by different security passcodes.
The DCS COMPACT also allows the use of a proprietary computer program called
CPCMMC. This permits a technician to program the system using a personal computer.
CPCMMC 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, CPCMMC can access a DCS COMPACT system remotely
(off-site) to make database changes or perform uploads or downloads of the customer
database as if the technician were on-site.

PART 2. HARDWARE DESCRIPTIONS
2.1 KEY SERVICE UNIT
The DCS COMPACT Key Service Unit (see Figure
2–1) is a single plastic cabinet containing the follow-
ing:

A power supply

Processing, switching and the system operating
program

Four Caller ID compatible loop start C.O. inter-
faces with a replaceable 4 C.O. protection card
(4COP)

Eight 2B+D digital keyset interfaces

One MOH/BGM input

One page output

One auxiliary relay

Power failure circuits for the first two C.O. lines
2.2 EXPANSION KIT
The optional expansion kit (see Figure 2–2) consists of a backplane PCB with connectors
for three 2 x 4 expansion cards and a plastic rack to support the cards. The kit is installed
inside the basic KSU and connects to the KSU motherboard via a 50 pin ribbon cable and
two pairs of ground wires.

2.3 RAM PACKS
To operate, the KSU must
be equipped with a RAM
pack to hold the customer
database (see Figure 2–
3). There are two types of
RAM pack available—
RAM packs 1 and 2, de-
scribed below.
RAM PACK 1 contains:

Customer database
contained in 256
Kbytes of battery pro-
tected memory and the
Real Time Clock circuit
RAM PACK 2 contains:

Customer database contained in 256 Kbytes of battery protected memory and the Real
Time Clock circuit

Additional 256 Kbytes of battery-protected memory for the Caller ID features and to
increase the speed dial library to 1500 numbers
2.4 INTERFACE CARDS
A. The 2 SLI card is installed in a dedicated slot on the KSU motherboard. The card
provides two single line telephone interfaces equipped with OPX protection and the
ability to provide a loop disconnect signal.
B. The 2 x 4 DLI card provides two Caller ID-compatible loop start C.O. interfaces and
four 2B+D DLI ports.
C. The 2 x 4 SLI card provides two Caller ID-compatible loop start C.O. interfaces, four
SLI ports for industry standard single line telephones and the ability to provide a loop
disconnect signal. NOTE: This card does not provide OPX protection.
D. The 2 E & M x 4 DLI card provides two two wire (TL11M) tie line interfaces and four
2B+D DLI ports.
E. The MISC 1 card provides a second MOH/BGM input, four page zone control relays,
two serial I/O ports and four DSP circuits. It is recommended that this card be used in
situations requiring heavy single line telephone use.
F. The MISC 2 card is similar to the MISC 1 but with the addition of Caller ID decoding
circuits.
G. The KDb-DLI board, if installed in a digital keyset, will provide a second DLI port for the
connection of a digital station device.
H. The KDb-SLI board, if installed in a digital keyset, will provide an SLI port for the
connection of a standard telephone device.
NOTE: The SLI port on a KDb-SLI cannot
provide disconnect signal or OPX protection.
