Usage
Enter the minimum valid duration of a disconnect signal for an incoming
call. Avaya Communication Manager will not recognize shorter
disconnect signals. This field cannot be blank. For Brazil pulsed E&M
signaling, use 600.
Usage
Enter the duration of the backward release signal your server running
Communication Manager sends at the end of an incoming call.
Usage
Enter the minimum interval that must elapse between a trunk's release
from an incoming call and its seizure for an outgoing call. This field cannot
be blank. This delay gives the far-end time to release all equipment after
the trunk is released.
Usage
Enter the maximum acceptable interval between an incoming seizure and
receipt of all digits. Intervals greater than this limit generate an inline error.
