Is ther any way to get statistics after a call. In particular counts
of the number of errors which needed correction and the number of
times the modems needed to retrain might give an insight. What you are
describing sounds very much like the stalls caused while modems
retrain. It is also possible that the Ascend is giving up during the
retrain and the call is being terminated at the Demon end, even though
your modem has not reported loss of carrier.
