Operator 1, 2
Parameters setting the Operator 1,2 function mentioned in 0, “Operator 1, 2“.
- Number, sets the operator’s DDI number (MSN, ISDN telephone or other ISDN terminal
number).
DISA
The chart sets the behaviour of the DISA service that can be de/activated in the “Routing
> Port modes” section (see
0).
- First digit waiting time is the time during which the calling subscriber gets the DISA
message and should transmit the first DTMF tone. If no number is detected during the
timeout, the operator is dialled-in if activated, if deactivated, the caller gets the busy tone!
- Next digit waiting time is the time of waiting for the second and further digits of the direct
dial number. If the next number is not detected during this timeout, the call is routed to
Operator 1 or 2. The Operator service must be activated.
- Number of DDI digits is the number of digits after which DDI to the PBX or an ISDN
terminal is made. If the DISA DDI has a lower number of digits than selected, terminate
dialling by pressing a #. It is recommended that all DDI numbers should have the same
number of digits to prevent the calling subscriber from pressing a #.
