Can anyone help me with the term that SBC uses to refer to disconnect
supervision?  I have an Adit 600 channel bank which has helped improve the
disconnect detection time down to about 8 seconds. This is still causing some
issues in particular with call progress on we are having a few disconnects while
calls are in session.

I have talked both to some local phone contractors and SBC directly and no-one
seems to know what I am talking about. The phone contractors new about the issue
with other phone systems but didn't know there was a way to fix it and SBC reps
seem to never have heard of disconnect sup.

Also I have seen some references to loop start with call sup as kewlstart is
there another name for this protocol? One of the local contractors thought that
SBC automatically drops line voltage on remote hangup, in which case I need to
know what signalling to program into the ADIT 600. I also have the option of
going  to groundstart signalling if this would fix the problem.
