ceases after the far-end sends answer supervision. If the timer expires, the switch
acts as if it had received answer supervision. On senderized operation, the timer
begins after the last digit collected is sent by the switch.
NOTE:
This field’s setting does not override answer supervision sent from the
network or from DS1 port circuit timers. To control answer supervision sent
by DS1 firmware, set the Outgoing End of Dial (sec) field on the
Administrable Timers page of the trunk group screen.
Receive Answer Supervision
Use this field to specify whether the network provides answer supervision for a
trunk group.
For Outbound Call Management applications, set this field to
y for trunks
supporting network answer supervision. For trunks that do not receive a real
answer, this field determines when the CallVisor Adjunct-Switch Application
Interface (ASAI) connect event is sent.
NOTE:
When you set this field to y, the Outgoing End of Dial (sec) field is not
displayed. The firmware timeout on circuit packs controlled by the Outgoing
End of Dial (sec) field is automatically set to
0.
