Installation and Maintenance Manual
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.

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.
T0 interface 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 T0 interface 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 associated switches in the
MDF associated with the T0 interface must be set to ON.
S0 interface termination
An ISDN S-bus must be terminated twice, once at the start and once at the end of the bus. The BT
Versatility S0 interface 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.

Back up Voice Module voice messages and Greetings
The ability to back up all the voice messages and greetings recorded on the voice module is available, so
that they are not lost if the system software is upgraded. Before the software download is started the
voice module information is retrieved using that option in Remote Management Software.
Once this is done the voice module is effectively deactivated, therefore it is unavailable to users trying to
record messages until the software download is completed and the voice module information restored
back to the system.
The voice module is now re-activated and available for use and all the greetings and messages present
before the software download are still present.

Cabling the unit
All Line and Extension circuit cabling is inserted from the top of the unit. There are breakouts as shown on
the top of the unit to facilitate routing of cables into the MDF area.
Cabling Break outs
Connecting the extensions
It is recommended that all extensions be cabled with 2 pairs. The Featurephones use all four wires and
standard phones use the a,b pair only.
Do not exceed the following resistance or distance limits when connecting extensions to the System Unit.
(The distances listed assume 0.5mm-tinned copper conductor is used).
• 67 Ohms, or 400 metres, for system Featurephones.
• 336 Ohms, or 2 kilometres, for a standard telephone
• 336 Ohms, or 2 kilometres, for a standard telephone connected to the external extension on the
Options Module
The Extension cables must be of twisted-pair construction, using insulated tinned copper wires of nominal
0.5 mm2 cross-sectional area. Category 5 cable must be used for all ISDN installations.
It is important that this size and type of wire is correct since incorrect types can result in unreliable
connections. Care should be taken to ensure that the cabling complies with all relevant cabling
requirements.
Run cable from each Extension location to the Main Equipment. Pass the cable through the cable entry
hole in the CCU or Expansion Module and terminate the Extension wiring at the appropriate connector in
accordance with the table below.
31
BT Versatility
Installation and maintenance Manual
Four wires per Extension are connected at the Main Equipment. Spare wires must be neatly laid back
away from the connectors. To prevent cross talk or interference, cable pairs should not be split or the
spare wire of cable pairs used.
All Extensions should connect into standard line jack units. 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.

Expanding an Existing system
Modules may be removed and re-inserted in a system without disconnecting the power. See page 39.
However if additional modules are being installed in a working system it is necessary to power the system
down before installing an MDF or Backplane.
If additional network modules are to be installed in spare slots, the system needs to be reset before the
switch recognises the new modules.
Installing an additional Network (Analogue or ISDN) module
Modules can be installed in spare slots on the system without powering the system down. However the
module will not be activated until the system is reset. This can be achieved by pressing the reset button
on the CCU MDF.
Pressing the reset button will invoke a warm reset and clear any calls in progress
Installing additional modules
The system must be powered down before installing an additional MDF on the Backplane. When the MDF
is installed it is recommended that the Module, and any additional Network modules that may be
required, be installed before the system is powered up. When the system is powered up the additional
modules will be recognised by the system.
The power must be disconnected before installing an MDF or Backplane. If Battery Back up is
provided ensure the BBU switch is off and the mains is disconnected.

Troubleshooting
All faults can normally be traced quite readily to a particular PCB. Prior to replacing any PCB, fault
conditions should be checked to see if they are caused by programming or mis-operation. The
Featurephone display will often indicate which system features have been set.
• System not initialising
Check that all system cards have been properly installed, with all connectors fully located.
• No incoming calls
Check that all phones programmed to ring are not programmed for DND or divert.
• Extension outgoing locked
If you cannot get outgoing access on a 2-wire telephone, move a Featurephone to the extension. If it
shows EXTN LOCK, the extension has been locked and you will need the unlock code to unlock it.
• No extension dial tone
Check that the extension has not been disconnected through programming.
• Not seizing a line for outgoing calls
•
•
•
Check if the line has been programmed for incoming calls only.
Check if the line is equipped in programming.
Check that the key is programmed for line access.
• Door intercom not operating
Check the programming for the door intercom.
• Phone reset
Remember the simple phone reset code 739, which can be dialled from any extension phone.
• System reset
Reset: To do a warm reset of the BT Versatility press the reset button on the CCU MDF. You may also
choose programming mode and choose system, reset options, and reset.
Reset to default: To do a cold reset of the BT Versatility, enter programming mode and choose system,
