Installation Of The Modular Cards
The DBS is configured using modular cards to support exchange lines, digital extensions, analogue extensions
and system control functions. These cards are installed in the CCU in designated slots. The numbers of slots and
hence the numbers of cards each CCU can support varies with the CCU used. The table below shows how many
of each card can be installed in each CCU.
Larger DBSs are created by linking a DBS 90 CCU to a second DBS CCU cabinet. the link is via the link cable
cards and cable (VB3691UK). The CCU which contains the CPC card and SCC card is the Master CCU and the
second CCU is the Slave CCU. When CCUs are linked in this way the AUX1 slot in the Master and SCC slot in the
Slave are not used.
Each CCU has one universal slot marked EXT/LINE which is capable of supporting all extension and trunk card
types. In a double CCU system there are two EXT/LINE slots, one in each CCU.
To install a card:
1Turn off the system power and remove the front cover.
2Hold the card to be installed with the connection strip facing the backplane of the CCU and the name label
at the top. Check that the card can be installed in the required slot.
3Locate the guides at the top and bottom of the card into the guide slots in the CCU and gently push the
card into the CCU. When it reaches the connection strip on the backplane a slightly heavier push will
engage the connectors and the card front twill be flush with the front edge of the slot.
4Rewire system MDF if required.
5Switch On The System.
Repeat 2 & 3 for each card to be installed.

Linking Two CCUs
CCUs are linked using the connection cables and cards VB3691. The master CCU must be a DBS 90. One CPU
card and one SCC are installed in the master CCU to provide control for the whole system. When two systems are
linked the SCC slot in the slave and AUX 1 slot in the master are not used.
1Remove the covers from the CCUs. Install the link cards in the AUX 2 slots at the right hand side of the
CCUs. Ensure the master card is installed in the master CCU and the slave in the slave CCU.
2Connect the wire provided on the slave card to the 24v pin of the 24v and GND terminal CN24 on the
slave CCU.
3If two DTMF Receiver (MFR) cards are fitted to the system cut the jumper wire marked J3 on either of the
MFR cards. Failure to do this will cause the MFR cards to cancel out and DTMF dialling will not be
recognised by the system.
4The first extension card of the master CCU must be a Digital extension card (DEC). The remaining
extension cards can be any combination of Analogue extension card (AEC) and DEC.
5Ensure the switch SW1 on the master connection card is set to the factory default shown in table 5 below.
6Connect the link cable to the cards through the access holes provided in the chassis of the CCUs.
7Connect the flying leads from the master end of the connection cable to a frame ground on the master
CCU.
8Allow for the reinstallation of the CCU covers and install the EMI filters as close as possible to the CCUs
at both master and slave ends.

Connection Of Exchange Lines And Extensions
To comply with EMC Directive 89/336/EEC and it amendments 92./31/EEC and 93/68/EEC, EMI filters must be
installed as per the EMI Filter Installation section later in this manual.
Connection of exchange line and extension wiring to the DBS is made via proprietary DDK connectors supplied
with the CCU. Additional connectors can be obtained as spare part items.
Each DDK can accommodate two exchange or extension connections.
The DBS can be directly wired to the Network Test an Termination Point (NTTP) via DDKs, however it is
recommended that an Intermediate Distribution frame (IDF) is installed and the exchange and extension wiring
jumpered across to the wiring running to the DBS.
Figure 6 - Recommended Connection Schematic
Attaching A DDK Connector
1Open the DDK.
2Insert the wires to connected into the four holes on the flap.
3Ensure the wires do not slip out of the holes and close the DDK using a pair of pliers to press the two parts
firmly together. The blades in the second section of the DDK will cut through the insulation on the wire and
make contact with the conductor.
4Plug the completed DDK into the appropriate port connection on the Master Distribution Frame (MDF) at
the top of the DBS CCU.

Piggy-Back Connections
The DBS can be used a host or subsidiary system. As a subsidiary system piggy-backed from the extension ports
of a host PBX the connection from the host is presented as a series of exchange lines to the DBS. The DBS is
then configured through programming to use those ports as piggy-backed lines and will provide recall signalling to
the host.
The DBS can be configured to provide earth or timed break recall signalling to the PBX. Timed break will operate
on the wiring from the PBX extensions. Earth recall will require the connection of an earth wire from the PBX earth
point to the PBX EARTH connection point on left hand end of the DBS MDF.
If an earth connection is required to the DBS this must also be carried across to the EXT/LINE slot wiring using a
DDK to DDK jumper wire so that any PBX extensions connected there can also send earth recall. The following
diagram shows the location of the connection points on the DBS CCUs.

Extension Connection
Extension connections are made via DDK connectors in a similar way to those for the exchange lines. Both Digital
and Analogue extensions connect using two wires. The DSS operator console is wired as a digital extension or
piggy backed with the operator extension. Extension ports 1 and 2 are the ports for operator extensions DSS units
when installed will operate with one or other of these ports as per system programming.
Digital Extension Connection
Digital Extensions are wired to secondary sockets pins 3 and 4.

Analogue Extension Connection
Analogue Extensions are wired to master sockets pins 2 and 5.
Figure 10 - Analogue Extension Connection
DSS Console Connection
DSS 1 for the operator extension on port 1 and DSS 1 for the operator extension on port 2 can be wired sharing
the same socket as the extension or wired as an individual digital extension. When the socket is shared use the
link wire supplied with the DSS to connect the operator extension to the DSS unit then connect only the cord from
the DSS unit to the socket.
The second DSS unit for each operator is wired as a digital extension.
DSS consoles can be connected to any vacant digital extension port supported by a digital extension card.

SLT Ring Generator
The SLT Ring Generator is a power supply to provide ringing voltage for analogue extensions. It is sufficiently
powerful to ring 20 analogue extensions at any one time. One Ring Generator is required for every CCU. When
installing a double CCU system one Ring Generator must be fitted to each CCU in which analogue extensions are
connected and required to ring.

Power Fail Telephone Connection
The DBS CCUs have a number of power fail telephone connection points. When a power failure occurs the first
few exchange lines are switched to the Power Fail Units (PFUs). 40% of incoming only lines and 20% of incoming
and outgoing lines must be supported in power fail mode. The DBS CCUs each have the following numbers of
power fail lines.
Table 6 - Power Fail Connections Per CCU
Connection of the PFUs is via DDK in the same way as analogue extensions. The DDK connections are located at
the left hand end of the CCU above the exchange line connection points. The highest lines are on DDK 1 and they
work downwards.

Doorphone & Doorlatch Interface
The doorphone and doorlatch interface is a separate unit which should be wall mounted externally to the DBS
CCU. It connects to one exchange line port which must be set for pulse dialling and the 24v and GND terminals
CN23. The doorphone unit supports two doorphones and has two doorlatch interfaces. Since it connects to a single
exchange line only one doorphone and latch can be used at one time. Should the second doorphone be used
whilst the first one is in use the extension talking the first doorphone hears an tone (Ping-Pong) and can either
press 2 to cut off the first call and answer the second or 3 to open the latch.
Doorphone calls which are not answered will be cut off after a pre determined time set by DIP switch settings in
the interface box.
The door latch is trigger is via relays OPENER 1 and OPENER 2. These are normally open relays which close for
a predetermined time set by DIP switches on the interface card. The relay is used as the switch in the latch circuit.
It can handle 1 amp at 30v DC or 50v AC maximum.
Figure 16 - Doorphone Interface Connections
* = Initial Setting Table 7 - DIP Switch Settings
Note 1: Switch positions 1 and 2 have no function.
Note 2: CN23 is a 4 pin DDK connection. Pins 1 and 2 provide 24vDC and 3 and 4 provide a ground connection.
Therefore connect to 1 or 2 and 3 or 4.
Note 3: To comply with EMC directives EMI filters must be fitted as indicated to the Doorphone Interface
connections. Refer to the EMI Filter Installation section of this manual for filter installtion details.
