2.3 COMMON CONTROL CARDS
CENTRAL CONTROL PROCESSOR (DCCP)
The DCS 400si system must have a DCCP card which contains the system software on
the DROMD daughterboard.  The DCS 400si Central Control Processor (DCCP) controls
the system operation. The DCCP installs in the DCCP/ECCP slot in the first cabinet of the
system. The DCCP is required for a one cabinet or two cabinet system operation. The
DCCP has a 256 time slot switch matrix and 4 DTMF DSP receivers built in. With a two
cabinet system a D4SWD daughterboard must be installed on the DCCP to expand the
switch matrix to 512 time slots. The addition of the D4SWD board also provides 16 DTMF
receivers. The DCCP supports the following options.

8 position DIP Switch (make busy IO, T1 clocking and default numbering plan)

Manual reset switch

MOH Volume Control

2 Page Relays (via 6 pin modular jack #1)

External Page Output / External MOH Input (via 6 pin modular jack #2)

MOH Internal Melody chip

2 SIO ports (RS-232c-9pin) (1 built-in and 1 optional)

8 LED’s giving operational status of the CPU, major and minor alarms, T1 clocking
and maintenance and administration indications.
EXPANSION CONTROL PROCESSOR (DECP)
To expand the DCS 400si to more than a single cabinet system, the expansion control
processor card is required in the second cabinet. The DECP processor communicates via
a high level data link control (HDLC) to the DCCP. The special HDLC cable connects the
DCCP to the DECP. The DECP can have one of two types of daughterboards installed on
it to increase the systems DSP resources for station use or Caller I.D. use.
2.4 INTERFACE CARDS
These cards provide the interface connections for telephone lines, stations and
miscellaneous functions to the DCS 400si. These cards fit into the universal card slots in
the main and expansion cabinet to configure the system as required. As the system utilizes
dynamic time slot allocation each interface card is assigned only the required number of
time slots or ports. This provides for more efficient use of the 384 ports.
8 UNIVERSAL TRUNK CARD (D8UTK)
The DCS 400si 8 port Universal Trunk card is selectable on a per circuit basis for loop
start, ground start, DID and E&M tie line type trunks. All trunk types supported are soft-
ware programmable. It can be inserted into any universal slot. Each D8UTK uses 8 ports.
16 CIRCUIT TRUNK CARD (D16TK)
The DCS 400si 16 port Trunk card provides 16 loop start trunks. The D16TK supports
Caller ID service and can be inserted into any universal slot. Each D16TK uses 16 ports.

DIGITAL TRUNK CARD (DTPRI)
The Digital Trunk Card (DTPRI) supports either T1 or PRI (ISDN) service. The DCS 400si
supports six T1/PRI cards per cabinet or a total of 12 per system.  The five LEDs on the
front of the card provide  indications for Activity, Synchronization, Loss of Signal, Alarm
Indicating Signal and Level 2 Activity. It can be inserted into any universal slot and uses 24
ports.
When used as T1 service this card provides up to 24 circuits in any combination of the
following signaling protocols:

Loop start

Ground start

DID (Direct Inward Dialing)

E & M tie trunk or two way DID calling
NOTES: Caller ID is not available on T1 span but Automatic Number Identification (ANI)
via inband DTMF signaling is supported.
When used for ISDN–PRI service, this card can support National ISDN (NI2), No. 5 ESS,
and DMS 100 custom protocols. It can be inserted into any universal slot. This card provides
up to 23 ISDN “B” channels and 1 ISDN “D” channel.
8 BRI (BASIC RATE INTERFACE–D8BRI)
The 8 BRI card supports 8 trunk or station level ISDN Basic Rate Interface (i.e., 2B plus D)
circuits. The nine LEDs on the front of the card provide ISDN (Layer 2 protocol) activity
indications per BRI circuit and one busy/idle LED. The DCS 400si supports 20 BRI S/T
(station or trunk) interface cards. It can be inserted in any universal slot. Each D8BRI uses
16 ports.
24 DIGITAL LINE INTERFACE (D24DL)
The digital line interface card provides service to all DCS keysets, 32 button AOM, serial
interface module (SIM), door phone interface module (DPIM) and the 64 button module.
This card is a twenty four circuit digital station interface card that provides selectable
1B+D service or 2B+D service. It can be inserted into any universal card slot. When se-
lected for 2B + D service each card uses 48 ports instead of 24. When selected for 1 B +
D service each card uses 24 ports.
16 SINGLE LINE INTERFACE with MESSAGE WAITING (D16SL)
This card is a sixteen circuit analog station interface for industry standard single line tele-
phones or other analog peripheral devices (voice mail, etc.). It provides the overvoltage
protection required for connection to the telephone company off premises extension cir-
cuits (OPX). Industry standard Message Waiting voltage for single line message waiting
lamps is also provided by this card. It can be inserted into any universal card slot. Each
D16SL uses 16 ports. 
						

							CONTENTS
24 SINGLE LINE INTERFACE (D24SL)
This card is a twenty four circuit analog station interface for industry\
 standard single line 
telephones or other analog peripheral devices. The 24 SLI does NOT contain any over-
voltage protection and does not qualify as OPX. It can be inserted into \
any universal card
slot. Each D24SL uses 24 ports.
KEYSET DAUGHTERBOARD –DLI (KDb-DLI)
This is a small daughterboard that can be installed inside any 24 or 12 \
button DCS keyset.
The KDb-DLI will provide one additional DLI circuit for the connection o\
f any digital station
device such as a keyset, add-on module, SIM or DPIM. This KDb-DLI will o\
nly operate
when the keyset is connected to a DLI card that is set for 2B+D operatio\
n so it can use the
second B channel. The KDb-DLI can not be installed in a 7B keyset.
KEYSET DAUGHTERBOARD–SLI (KDb-SLI)
This is a daughterboard that can be installed inside any 24 or 12 button\
 DCS keyset. The
KDb-SLI will provide one additional SLI circuit for the connection of an\
y standard tele-
phone device. This KDb-SLI will only operate when the keyset is connecte\
d to a DLI card
that set for optioned for 2B+D operation so it can use the second B chan\
nel. The KDb–SLI
can not be installed in the 7B keyset. 
NOTE: The circuitry on a KDb-SLI does not provide a physical loop open d\
isconnect 
signal or have the overvoltage protection necessary for OPX operation.
AUTO ATTENDANT / UCD (DAAUP)
This optional card can be used for either the Automated Attendant, Unifo\
rm Call Distribu-
tion or a combination of both. Each DAAUP card provides 8 ports of autom\
ated attendant
and memory for four (4) minutes of recorded announcements for either A\
A or UCD opera-
tion. A maximum of 5 DAAUP cards can be installed in either a single or \
two cabinet
system. For more information about the Automated Attendant and UCD,  see section 4.1

							CONTENTS
c. MOH Internal Melody #2
d. 1 Modular 6 Pin Modular Jack for External (2 inputs) MOH inputs
e. 1 Modular 6 Pin Modular Jack for External Page (2 outputs) and Alarm Contacts
The DMAP1 card must be installed in the main cabinet. There can only be one DMAP1 in
a two cabinet system.
2.5 POWER SUPPLY (DPCU)
Each DCS 400si cabinet can contain either one or two plug-in power converter units (i.e.,
system power supply). The power converter units can be powered by either 110/220 volt
AC or -48 volt DC input. The DPCU converts these input voltages to +5 volts, -5 volts and
48 volts DC output power to the DCS 400si system.
Multiple DPCUs provide a more cost efficient and serviceable method to meet the various
configurations of stations and trunks. Each DPCU can power 96 devices. The devices are
determined as circuits that require 48 volts DC from the system. To calculate the 48 volt
load, count each device as one unit of power times the number of circuits per card. For
example a 24 port DLI card (D24DL) supplies 48 VDC to each keyset so each DLI port
counts as 1 power unit. Therefore each D24DL counts as 24 power units. The following
interface cards use 48 VDC and count towards the total required power units.
1. D24DL (1B+D) 24 power units
2. D24DL (2B+D) 48 power units
3. D24SL 24 power units
4. D16SL 16 power units
5. 8UTRK 8 power units
Other types of interface cards do not use 48 VDC from the system supply so they should
not be counted.
2.6 SYSTEM DAUGHTERBOARDS
DROMD DAUGHTERBOARD
The DCS 400si ROM daughterboard (DROMD) mounts on the DCCP and supports up to
8 Mbytes of program memory space to support the system operating program. This board
is equipped with sockets and the EPROM chips that contain the system program (soft-
ware) plug into these sockets. Thus, the EPROMs are plugged into this daughterboard
and it is plugged as a single unit into the DCCP board. This makes it physically easier to
change system software. Every DCS 400si system must be equipped with a DROMD
daughterboard to operate. The EPROMs are not included with the DROMD. The software
must be ordered separately.
DCDM DAUGHTERBOARD
This optional, but highly recommended, Customer Data Module board mounts on the
DCCP and provides 2 Mbytes of “Super Capacitor” backed RAM memory. This allows for
a separate removable database storage location on the DCCP board. Thus, it supple-
2.5 
						

							CONTENTS
ments the 2 Mbytes of on-board battery backed RAM. The purpose of the DCDM is to
provide a convenient, fast, easy to use, and reliable means of restoring a database to the
DCCP board. It is primarily used as:
a. a diagnostic tool to check for a faulty DCCP board
b. a means to allow defaulting the system database (e.g., to check for customer data-
base programming problems) while still preserving the original database, and
c. a means of restoring a specific database in 2-3 minutes to a new or existing DCCP in
support of a and b above.
Due to the fact that during a PCMMC database upload the system database is changing
over a 25 to 30 minute period, system call processing operation must be halted during the
upload process. Thus, an upload should only be done during periods of time when loss of
system call processing will not affect the customer’s business operations (e.g., after work-
ing hours). Consequently, providing a DCDM allows a means for rapid restoration of a
system database (i.e., within a few seconds) without incurring this lengthy interruption of
system call processing capability. It should be remembered that specific entries in the
system database can always be changed using KMMC or PCMMC in the on-line mode
without incurring the loss of system call processing produced by a full or partial PCMMC
database upload.
D4SWD DAUGHTERBOARD
The DCCP must be provided with a D4SWD daughterboard to expand the system-switch-
ing matrix from 256 ports to 512 ports. However, adding this daughterboard also adds 16
DTMF receiver resources and a gain/loss controllable conference package to the system,
which allows the system to provide a higher quality conference arrangement for 4 and 5
party conference calls. Now, it is possible to provide the D4SWD daughterboard to the
DCCP simply to add the DTMF receiver resources and higher quality conference capabil-
ity without expanding to a second shelf. Thus, in future, expanding to a second shelf
becomes easy.
The DCCP has 4 DTMF receiver resources on-board, the DECP has none, and the MAP1
has 16 DTMF receiver resources on-board. Adding a D4SWD daughterboard  to the DCCP
increases its and the system’s DTMF receiver capability to 20 (i.e., 4 on-board plus 16 on
the D4SWD daughterboard). Adding a D4SWD daughterboard to the DECP adds 16 DTMF
receiver resources to the system total. Finally, adding a D4SWD daughterboard to the
DMAP1 board provides a total of 32 DTMF receiver resources to the system (i.e., 16
DTMF receivers on-board and 16 DTMF receivers provided by the D4SWD daughterboard).
DR2CID DAUGHTERBOARD
The DCS 400si 24-channel CID (Caller ID) detector daughterboard (DR2CID) mounts on
the DCCP, DECP or the DMAP1. The DR2CID provides up to 24 receivers for CID detec-
tion maximum when plugged on to the DCCP and/or DECP cards. When the DR2CID
daughterboard is plugged on to the MAP1 card, it will only provide 16 caller ID receivers
(i.e., since the on-board DTMF receivers already use 16 time slots and the entire board is
2.6

only allocated 32 service time slots maximum). These time slots are not associated with
the 192 universal time slots.
DSIOD DAUGHTERBOARD
The DCS 400si SIO (Serial Input/Output) daughterboard mounts on the DCCP card. This
DSIOD provides 1 additional isolated 9-pin RS232 serial port (i.e., in addition to the on-
board 9-pin RS232 port) on the DCCP. The DSIOD 9-pin connector  #2 on the DCCP has
a maximum data speed of 38400 bps.
DRAD DAUGHTERBOARD
The DCS 400si 2-channel DRAD (Data Rate Adapter) daughterboard mounts on the DCCP
card and allows for the use of 2 Serial Interface Modules (SIMs) on the DCS 400si system.
There are no options to select on this daughterboard. SIM settings are controlled via
KMMC and/or PCMMC programming.
