PABX Mode

The BT Versatility can be set, through system programming, to Operate in either PABX or Key
System Mode of Operation. The switch works in Key System Mode by default.
When PABX Mode of Operation is selected a number of changes are made to the operation of the
system.

Line appearances on Featurephone keys

Line keys programmed on the phone are not associated with particular lines. When a line key is
selected on a phone the line light is lit only on the phone selecting the line.

Making external calls when in PABX mode

External calls can be made:
• By dialling the line access digit
If the Featurephone is programmed with a Line Key or Keys, the light on the first available line
key is lit.
• By selecting an available Line Key:
If a free line or B channel is available an external dial tone is returned and the light associated
with the Line Key is lit. If no line or B channel is available a busy tone is returned and the Line
Key light is not lit. Instead, the display indicates that no line is available.

Incoming Calls In PABX mode of Operation.

Incoming calls made to ring Groups, Extensions, Auto Attendant, Courtesy Service or System
voicemail box
This programming is the same for both PABX and Key system Modes of Operation.
When a call is presented to a Featurephone the phone is called and the light on the first available
Line Key on the Featurephone flashes at the Ringing Rate.
If the call is presented to an individual phone the key associated with the first available Line key
on the phone flashes at the Ringing rate. No Line key on any other Featurephone is lit.
If the call is presented to multiple Featurephones in a Ring Group, the line key light is lit on all the
Featurephones in the group with an available Line Key. No other Line key on any other
Featurephone is lit.
If the call is presented to a Featurephone with no available Line Key the call rings the phone
without lighting any Line Key.

Call answered

When a call is answered the light associated with the line Key on the answering phone is lit
steadily. The light associated with the call on all other Featurephones, if the call was presented to
a group, is extinguished. An answered call lights up on the Featurephone that answered the call.

Call Placed on Hold

If a Featurephone places a call on hold the light associated with the Line on the Featurephone
flashes at the Hold Rate. No other Line Key on any other Featurephone is lit.
The Option to 'Return to line' is given on the Featurephone menu. The phone returns to idle.
