To programme Loop Calling on Analogue system Lines

All Analogue lines are programmed by default to use standard Analogue signalling.
You can programme your Analogue lines to use Loop Calling if required. The benefit of
having lines programmed for Loop Calling is that the line will not be disconnected by
the switch if a digit is not dialled.

Programming Guarded Clear

On standard Analogue lines on the BT Versatility the Guarded Clear option is
programmed. The system can then detect when callers go on hook and automatically
clear down lines. This supervision on lines enables the trunk to trunk services to be
available on the lines.
If guarded clear is turned off then the trunk to trunk services are not available as the
system cannot detect when calls have been completed.
