Hold and ring timers
The system provides many programmable timers to change the duration of ringing and the time
exchange line calls can be left on hold or unanswered.
Exchange line hold timer.
When a call is placed on hold using the Hold key or the R00 sequence on a telephone it will remain
on hold for a programmable length of time between 30 seconds and 4½ minutes. After this timeout
the call will ring at the extension which put the call on hold. If this extension is busy, or not answered
for 30 seconds then the call will ring as a general incoming call.
Default
An external call on hold will timeout and call back after 1 minute.

Exchange line park timer

programmable length of time between 30 seconds and 4½ minutes. After this timeout the call will
ring at the extension which put the call on park. If this extension is busy, or not answered for 30
seconds then the call will ring as a general incoming call.

Exchange line call camp timer
When a call is placed on camp while the extension is busy by dialling 3 on a telephone it will remain
on camp for a programmable length of time between 30 seconds and 4½ minutes. After this timeout
the call will ring at the extension which put the call on camp. If this extension is busy, or not
answered for 30 seconds then the call will ring as a general incoming call.

between 15 seconds and 135 seconds. After this timeout the ring will stop.

Unannounced transfer timer
When the incoming call is transferred blindly to another extension (see ‘Transferring calls - Internal
unannounced’ on page 7), it will remain ringing for a programmable length of time between 15
seconds and 135 seconds. After this timeout the call will ring as a general incoming call.
Set Blind transfer extension ring timeout delay
Call back extension
This timer is started after the extension ring timer has expired and no-one has answered the call.
When this timer expires, the external caller is cut off.
Set Call back extension ring timeout delay
Hot Line Programming
There are two Hot Line features Immediate and Delayed. Immediate Hot Line allows a pre-
programmed telephone number to be dialled immediately when the extension user lifts the handset.
Delayed Hot Line Services are activated after the extension user lifts the handset and a timeout has
expired. A pre-programmed number is dialled automatically after the timeout of approx. 10 seconds.
