The modems started answering the phones when there was no call. The result, predictably, was lots of screaming modems (The "your phone is off the hook" noise). The problem turned out to be a servicing error at the local #5ESS switching office. They has replaced some of the line cards and had set them up wrong. Evidently the line voltage was high enough to confuse some devices into thinking it was time to go off-hook. The modems in this case were Microcoms, and they evidently (according to our hardware types) were properly within spec. -- Daniel Senie UUCP: harvard!ulowell!cloud9!dts Stratus Computer, Inc.
