David,
I am on Ameritech in Southern Illinois. We have a Northern Telecom DMS-100
switch. I was under the impression that the DMS-100 would only allow one
analog connection over ISDN on a BRI circuit. The second B channel could
only be data. Have you or any one else heard anything like this? Does anyone
know of a source of information on what can be done with the DMS-100?
Ameritech for the most part doesn't even know. You get a different answer
most times when you call. I have been using I-modems provisioned with only
one B channel to serve x2. This works but it is very expensive in comparison
to PRI. Sorry off subject.
