Hi Everyone...
Long ago, I aquired about 6 phones and a KSU from a friend's office. Each of the telephones have "TIE Communications" on the back of them, but 2 of them also have "Pac Tel" on the front. All of the phones look pretty similar. As far as the KSU, I have the feeling that it is the wrong one. It says AT&T on the back, and it has ports on the front for the incoming lines, 2 standard phones, and 6 extentions. When I plug any of the phones into one of the jacks for the 6 extentions, I get this clicking noise coming from the receiver (or the built-in speaker). None of the bottons light up or work. If I plug a standard phone into the first standard jack, and connect the KSU to my phone line, I can get a normal dialtone from which I can dial directly out.
My problem lies with trying to figure out why the phones do now work with this KSU (because they are from the same office). I also can not seem to identify the model of the KSU. I have looked up pictures of the AT&T Merlin, Partner, and Spirit series, and none look the same. There is no other information besides the logo on the back of the KSU.
Any ideas or information that anyone has would be greatly appreciated. I have been trying to figure this out for years, and just can't seem to do it. Thanks in advanco for the help!
