[comp.dcom.modems] False Rings on V.32bis

WILLIAMS@GAMMA.IS.TCU.EDU (03/01/91)

Floyd, thanks for the suggestions.  They were right.  Here's what was happening:

SWBell sent a troubleshooter out and she determined that there was a short - not
in the modem or in the lines running to the modem, but in the Y/BK leads of
ANOTHER USR V.32bis that my roommate has in his room.  His RJ13 was wired so
that his data line was connected to the red/green pair and my modem line was
connected to his yellow/black pair.  Since the V.32bis Dual Standard no longer
supports A/A1 signaling, the modem had a partial short on the second pair and
was shorting my line.  We disconnected my data line from the yellow/black pair
and the RING problem disappeared.

Thanks for your suggestions.
