[comp.dcom.telecom] Northern Telecom DMS-100

I also had trouble at 1200 baud when my CO cut to a DMS-100.  You'll
know this baby by the sound.  There are no clicks generated.  Local
calls go from dialing to ringing to connecting with nary a hard click.
Also, the call waiting beep has no clicks surrounding it either.
Finally, calling up repair service and asking them may produce the
info that it is/is not a DMS-100.

Now, when I had this problem, I was able to escalate the problem to
the point where a technicial would talk to me, and she changed the
line card on my line, curing the problem.  Unfortunately, she did not
know what was different between the old line card and the new one.
She said (as you did) that something was out of phase.  She said that
she'd continue changing line cards for me until I got a good one, but
the first one she tried worked fine.  Never had a problem again.

The problem is that the whole thing is so damned nebulous that it's
impossible to cite an applications note or other document to convince
the phone company that there is a problem.

Only suggestion, try to talk to someone technical, try to get them to
change the line card, and good luck.
