Installing The Built In Backup Batteries
There are two types of internal battery. One type for the DBS 38 and another for the DBS 68 and DBS 90. Use the
set appropriate to the CCU being installed.
1 Link the batteries together as shown below.
2 Connect the red and blue leads to the + and - terminals respectively of the end batteries.
3 Insert the batteries into the bay in the CCU.

Table 3 - Internal Battery Specifications
Note 1: The batteries can maintain system operation for approximately 30 minutes for a DBS 38 or DBS 68 or 15
minutes for DBS 90. The duration of system operation on battery power is dependant upon the traffic
conditions at the time.
Note 2: Panasonic recommend replacement of the backup batteries every three yeas.
Note 3: The parts listed in table 3 are recommended. However any batteries which meet the specification can be
substituted.

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:
1 Turn off the system power and remove the front cover.
2 Hold 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.
3 Locate 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.
4 Rewire system MDF if required.
5 Switch On The System.
Repeat 2 & 3 for each card to be installed.

Note 3: A maximum of 2 E&M cards can be fitted to any CCU. The DBS 38 CCU can take 1, the DBS 68 and 90
CCUs can take 2. Refer to the E&M card installation instructions for full details.
Note 4: A maximum of 1 ISDN card can be fitted to any system regardless of size. It must occupy a universal slot.
See ISDN card installation instructions for full details.
Important
The first extension card fitted to a system in slot EXT1
MUST be a digital extension card

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.
1 Remove 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.
2 Connect the wire provided on the slave card to the 24v pin of the 24v and GND terminal CN24 on the
slave CCU.
3 If 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.
4 The 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.
5 Ensure the switch SW1 on the master connection card is set to the factory default shown in table 5 below.
6 Connect the link cable to the cards through the access holes provided in the chassis of the CCUs.
7 Connect the flying leads from the master end of the connection cable to a frame ground on the master
CCU.
8 Allow 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
1 Open the DDK.
2 Insert the wires to connected into the four holes on the flap.
3 Ensure 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.
4 Plug 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.
Figure 7 - PBX Earth Connection Points
Exchange Line / PBX Extension Wiring
Use each DDK to connect two circuits as shown.

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.
