1A2 Newbie - 07/25/12 07:12 AM
Yesterday I got called out to a this house whose owner was complaining about problems "on the line." I've always been fascinated by analog phone systems, however as with so many things, I'm finding that I was born just a bit too late, and I've never really gotten to work on one.
Well, this house has a 1A2 system that the owner had installed sometime in the 60s, and she loves it. In fact, she had them installed everywhere she moved, back when they were available, and she has a pile of parts in her barn that she's saving in case she ever buys another house. (good luck finding someone to put it in).
In any case, I'm really excited to tackle this one, but am in completely uncharted territory for me, so I thought that I would ask for some guidance here.
Over the winter the house was re-wired, and one cable that was previously run up the side of the house was cut and re-run through the wall. The technician who did it simply cut the sheething in two places and used crimps (those little red, crunchy, 3M things) to put the pairs back together prior to where the connector attached to the headset and near the KSU in the basement.
The system has 2 lines, and an intercom. The problems are two fold:
1) Line 1 does not flash when it rings, but the ringers do function and line is usable.
2) When dialing the intercom, line 2 will flash as though it was ringing (not winking), but if you switch over there is dial tone, and no caller. Then switching back to the intercom causes the light to go out and the intercom functions as expected.
So far these are the only two gremlins that have been demonstrated to me, but I can't say that's all there are. My first inclination was that the pair connected to the lights was shorted/crossed/disrupted in the punchdown block. However, every phone on the system displays this behavior, so I don't think that one miss-wired extension would make the entire system do this.
Sorry for the long post. But I'm really excited to get my hands on one of these, finally... I hope I can get it sorted out. Thanks guys!
