Safety Precautions during installation
and system upgrades
Always unplug or isolate the mains supply when installing or
upgrading the system.
After installing the central control unit (CCU) and all required
modules, ensure that the following points are checked before
switching the mains power on:
• The cabled extensions have a DTMF telephone or a (V8/V16)
Featurephone connected.
• The CCU cover is in place and locked.
After switching on the Mains allow approximately 30 seconds for the CCU to go through
its power up routine.
Electrostatic precaution (ESP)
The BT Versatility contains electrostatic components. To ensure long-term reliability of
the system, electrostatic precautions should be taken when handling any of the system
PCBs that are not enclosed in plastic. An ESP pillar is located on the CCU MDF.
Lightning and surge voltage protection
Extension cabling should not be exposed to high voltage surges,
(for example, surges induced by lightning or neighbouring high
current-carrying cables). If this is a possibility, external protection
of the Main Equipment and Extensions using ‘earthed line surge
protectors’ is essential.

Installing the Central Control Unit
CCU Location(CCU)
The CCU is intended for installation in a residential or office-type environment. It needs
to be mounted at a convenient working height on a dry, flat wall. The normal height is
1.5 m from the floor to the bottom of the CCU case.
Do not site the CCU where it will be subjected to excessive levels of heat,
dust, damp or high humidity. Locating the equipment near sources of
electromagnetic radiation, such as heavy electrical switch gear, lift
machinery or electric arc welders, should be avoided.
Allow at least 150 mm of free space all around the CCU for ventilation.
The CCU needs to be located within two metres of a dedicated mains power supply
outlet. The CCU must not share the same mains supply socket with any other electrical
appliance.
Mounting the CCU
When a suitable location has been found, mark the screw locations on the mounting
surface, using the mounting bracket provided.
If the CCU is being mounted on masonry or plasterboard, suitable wall plugs must be
used. Drill and plug four holes in the wall at the marked locations. The holes should be
deep enough to accept a 2.5cm screw.

CCU Mounting bracket clearances
The main unit is mounted on a wall using the bracket supplied and should have top and
side clearance as shown below.
CCU Mounting Bracket
If the system is to be equipped with a Ports, Options or Internet module then two
mounting brackets need to be installed.
CCU Bracket + Backplane Bracket

Mounting the CCU
The CCU is mounted on the bracket by sliding it on from the left hand side. The marks on
the side of the CCU must be lined up with the flanges on the wall bracket as shown below
before sliding the CCU into place. When you slide it fully to the right-hand side of the

Modules located in the CCU
There are a number of modules that can be installed in the CCU:
• Analogue Line Module (Coloured Black). This provides 2 Analogue exchange lines.
Up to two of these modules can be installed in the CCU to provide two or four
Analogue lines.
• Digital Line Module (Coloured Red). This card provides one ISDN 2 Basic Rate
Interface. The same module is used for the network T interface and the internal S-bus.
Up to two of these modules can be installed in the CCU providing one or two Basic
Rate Interfaces.
There are two slots in the CCU for the Network modules. If required one
slot can be equipped with an Analogue module and the other with an
ISDN Module:
• Voice module 2 or 4 port (Coloured Blue). Only one of these modules can be inserted
in a unit.
• Primary Rate ISDN module (Coloured Yellow). This module provides for a Primary
rate ISDN interface. Up to 30 B-channels can be provided. (Availability TBC).
When a Primary Rate Interface is installed, the unit can be further
equipped with one or two Analogue modules or one or two ISDN Basic

System Expansion
To equip the switch with more than 8 extensions or to add an Internet or Options
module, a backplane, mounted on a second wall bracket, is needed.
The power must be disconnected to install the backplane or
expansion modules.
Installing the Backplane wall bracket
The CCU and Backplane brackets are identical. However when both are installed the
backplane bracket is inverted so that it meshes closely with the CCU bracket.
Locate the second bracket and mark the screw holes. Drill and plug the holes in the wall
at the marked locations. The holes should be deep enough to accept a 2.5 cm screw.
Mount the second bracket ensuring the two brackets are correctly interlocked and that
sufficient clearance is provided on all sides.
Mounting the CCU with two brackets
Slide the CCU on to the brackets from the left-hand side. Ensure that the locking
mechanism is activated.

Mounting the Backplane
Slide the backplane on from the right hand side. Ensure the connector is fully mated
with the CCU.
Securing the backplane to the wall bracket
A mounting screw is used to securely locate the backplane on the wall bracket. This
provides additional rigidity to ensure the backplane and CCU connectors do not move.
Remove the fourth and fifth cover from the backplane.Locate the backplane on the
bracket and connect it to the CCU. The backplane must be fully connected to the CCU to
correctly locate the mounting screw hole. Insert the screw into the pillar on the bracket,
which can be seen through the backplane mounting screw hole.

There are three types of expansion module that can be installed on the back plane.
These are the Ports Module, the Internet Module and the Options Module. All these
modules are installed in the same way.
Modules are supplied in two parts. The MDF, which is connected to the backplane, and
the module which is inserted into the MDF.
The Ports MDF is also equipped with two connectors for the Analogue and/or the ISDN
Basic Rate modules.
The power must be disconnected when installing the Backplane or
expansion modules.

System ISDN settings
The system can be configured with 8 Basic Rate ISDN interfaces. Half of these can be
configured for internal S-bus operation.
The second interface on the CCU and each of the Ports Modules can be programmed as
S-bus interfaces for ISDN to-the-desk.
T0interface termination
An ISDN bus must be terminated twice, once at the start and once at the end of the bus.
The Network Terminating Equipment (NTE) will provide the termination at the start of
the bus. The end termination is also provided by the NTE if the BT Versatility is directly
connected to one of the NTE RJ45 sockets.
If ISDN 2 extension cabling and sockets are provided between the NTE and the switch
the end terminating resistor will normally be provided by an ISDN type 2 RJ45 line jack.
In both of these cases BT Versatility T0interface does not require the terminating
resistor to be connected and the associated switches in the MDF associated with the T0
interface must be set to OFF (Default).
Note: In the case of structured cabling if no end termination is provided, the switches in
the MDF associated with the T0interface must be set to ON.
S0interface termination
An ISDN S-bus must be terminated twice, once at the start and once at the end of the
bus. The BT Versatility S0interface emulates the Network Terminating Equipment
(NTE) and consequently is always terminated with 100 ohm resistance. In this case the
switches associated with the interface in the MDF must be set ON.
