TIMER=
Call connection timeout period
(default, 60 seconds)
This is the period of time that the DVST will wait while trying to connect
a call. This will vary depending on the type of call (ISDN or PSTN) and
as there may be a delay in establishing International calls, the timer
value should be increased.
DIALCLR=
...Sets time dial menu remains on screen
(default, 30 seconds)
10.4 Callback
This feature allows an operator to dial a remote unit and then have that unit
automatically call the operator back. This can be a useful security feature. The operation
of callback is as follows:
Local unit calls remote unit.
Call connects.
Local unit passes the dial menu number (0 to 9) that the remote unit will call back.
Call disconnects.
The local unit waits for a return call.
Remote unit waits for ten seconds then calls local unit.
Local unit answers and contact proceeds as normal.
CALLBACK=
Set call back ON or OFF
(Default, off)
When the callback feature is switched on the option appears on the
dialling menu to make either a normal call or a remote callback call.
Normal call is the default and this is highlighted. By using the left and
right arrow keys remote callback can be selected and deselected.
Note: Callback must be enabled on BOTH the transmit and receiving units
