Well, the power problem was easy to fix. Inside the PBX, someone had disconnected one of the live AC leads froms the screw terminal, and wrapped the end in electrical tape. Once I figured out where it went (Which was easy, it was the only unscrewed screw...) and applied power, it did all sorts of fun stuff. First, the console gets VERY confused when the things boots, and for about 30 seconds or so, the alarm goes off, all (or most of) the lights come on, and all of the various tones (intercept, dial, busy, etc.) sound at once. The tones themselved sound the same as the tones on the public network today. I was hoping for something interesting... Also, I found out the PASS and FAIL lights on the test panel are burned out. I'll have to replace them. The next thing to do is to connect some stations to it and see what happens. I think I have the proper wiring for this... Also, does anyone have the pinout of a trunk connector? You see, all we have at the destination of the PBX (Which is where I work) is Centrex service, and it sucks because we can't do PBX type stuff like music on hold, or transfer calls around, or pick up on any line from any phone... Right now when the phone rings or we have to pick up on certain phones (Cause not all of them have 4 lines, and of those that do, not all of them work.) and it's a general mess. So, what's going to be connected to this (if possible) is just 5 straight phone lines, and we'll have the Centrex service cancelled. (That way we don't have to dial 2 9s for an outside line.) SO far, from the console, I can snag a loop, and get an internal dial tone. If I dial 9 (It is touch-tone), I can get an outside line, but there's nothing on it so it's just silent. Also, I need to clean out the console buttons, right now you have to mash pretty hard to make a button go. Other than hat, I haven't been able to test much. There's no fans, and no loud noises, it just kinda sits and hums. OH, and I did (try) doing some of the test described in the DLP books, but a lot of them refrences use of a MAAP device, which is (apparently) supposed to be located in the PBX cabinet, but it isn't. The others refrence use of an "X-Ray" tape, I guess this is like XXDP to a PDP-11. But I don't have it. SO I just skipped those. Also, is there a special mailing list somewhere for people who play with old phone stuff? This is getting pretty interesting, and I really hate to keep perstering people here with this... Anyway, more tomorrow when I drag a few extensions in! -------
