Outgoing End of Dial (sec)
This field controls firmware answer supervision timers on circuit packs that have
them. It appears when the Direction field is
outgoing or two-way and the Receive
Answer Supervision field is
n. If the Receive Answer Supervision field is y, this
field does not appear and the firmware timer on the appropriate circuit pack is
automatically disabled.
NOTE:
The Answer Supervision Timeout field on the Trunk Group screen provides
timed answer supervision for circuit packs without administrable timers.
Since trunk groups may contain ports on more than one circuit pack, it’s
possible you may need to use both timers with the same trunk group. If so,
set the Outgoing End of Dial field and the Answer Supervision Timeout
field to the same value.
During a cut-through operation, timing begins after the switch sends each
outgoing digit and ceases when answer supervision is received. If the timer
expires, the switch acts as if it has received answer supervision. On senderized
operation, the timer begins after the switch sends the last digit collected. The timer
ceases when answer supervision is received. If the timer expires, the switch acts as
if it has received answer supervision.
Outgoing Glare Guard (msec)
This field only appears for outgoing and two-way trunk groups.

Enter the minimum interval that must elapse between a
trunk’s release from an outgoing call and its seizure for
another outgoing call. This field cannot be blank. This delay
gives the far-end time to release all equipment after the
outgoing trunk is released.
