Interface Companding
The entry in this field must match the companding method used by the far-end
switch. This field does not appear for all DS1 circuit packs.
Interworking Message
This field determines what message the switch sends when an incoming ISDN
trunk call interworks (is routed over a non-ISDN trunk group).
ITN-C7 Long Timers
This field controls the T302 and T303 timers. It only appears if the Signaling
Mode field is
isdn-pri.
Use the following values for private networks (including QSIG networks)
outside the U.S. Entering either of these values causes the Peer Protocol and
Side fields to appear.
peer-master
Enter peer-master if your switch overrides the other end
when glare occurs.
peer-slave
Enter peer-slave if your switch releases the contested circuit
and looks for another when glare occurs.
Valid entries Usage
alaw
Enter alaw for E-1 service.
mulaw Enter mulaw for T-1 service.
Valid entries Usage
PROGress
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
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.
Valid entries Usage
y
Use if you want to increase the length of the long timers.
n
Leave n if you want to use the default long timers.
