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.
