Network Deflect

Call Deflection is an ISDN service available from your ISDN Network Provider, which allows you to
divert calls from an incoming ISDN Line.
This option should be set on if the Call Deflection Network service is provided on the ISDN lines.
When activated external diversions set up by extensions or groups are diverted using the Network
deflect service.
The Call Deflect service is turned on in System Programming. It is one of the ISDN programming
options in the Line Programming.
Set up external call diversions in the normal manner. See section on Page 22.
When an external call is received for the extension the switch sends a message to the Network to
deflect the call.
The call is diverted by the Network to the number programmed by the extension.
Security Warning: It is possible that an extension may misuse the Network Deflect facility.

Using ISDN to the desktop

The BT Versatility can be equipped with an interface to an internal ISDN bus, which allows ISDN
devices to use your system ISDN lines. When the BT Versatility is equipped with
four internal ISDN buses can be provided.
Each of the ISDN buses can be equipped with up to eight ISDN devices. Four of these can be
powered from the BT Versatility, the remaining four, if equipped, must be independently
powered.
Eight extension numbers are allocated to each ISDN internal bus interface. The first interface is
allocated extensions 110 – 117, and the second is allocated extensions 120 – 127, the third is
allocated extensions 130 - 137 and the fourth is allocated extensions 140 – 147.
Incoming data calls are presented to an internal ISDN bus when one its ISDN extension
numbers is programmed in the ringing group. If an appropriate device is connected to the
internal bus, the call will be presented to it. For example, if you connect an ISDN fax machine
to the first S-bus interface of your system and programme an MSN number to ring extension
110 directly, then callers can use this MSN number to send you ISDN faxes.
