1188 Administrator Guide for Avaya Communication Manager
Usage
Leading zeroes considered significant and not ignored.
Usage
If set to y, the SPID field must not be blank. Avaya
Communication Manager blocks you from changing
this field and the SPID field unless that port is busied
out or unadministered.
If set to n, the SPID and Endpt ID fields must be blank.
Usage
Normally select this value. PROGress asks the public
network to cut through the B-channel and let the caller
hear tones such as ringback or busy tone provided over
the non-ISDN trunk.
ALERTing causes the public network in many countries
to play ringback tone to the caller. Select this value only
if the DS1 is connected to the public network, and it is
determined that callers hear silence (rather than
ringback or busy tone) when a call incoming over the
DS1 interworks to a non-ISDN trunk.
