Hey,

I have a Nortel\Norstar phone system and the first trunk line is either static, dead, or plays an AM radio station. Once in a great while it gets a dial tone. As a temp solution until I get someone in to check it out, I was trying to reorder our lines so this one is used last instead of first when someone tries to call out. I can't find anyway of doing that. I even just switched the wires with 004 line and that didn't work.

The book I have on the system says this on the front.

Besides that I don't know how else to ID the system. It's a simple setup for an office of 30 with voicemail and 5 external lines.

It might be that reordering them won't even help since it seems like a cabling type problem, but now that I've started to try to figure out how to reorder the lines I can't help following it through to the end.

Thanks for any help.

If you changed the cross connect and the problem stayed on the same line in the system. Then you are probably right it is a cable issue and reording will not help.
 
When I worked at the phone company 20 years ago we used to put non-polarized capacitors across the tip & ring to filter out radio interference. They were something like .47 microfarads if memory serves. If you have one around this value you might try it until the line gets repaired. As silver987 said it sounds like an unbalance on the line.

Thanks for the replies!

So who do you think would service the problem? The vendor who setup my Norstar system or Verizon who put in the phone line? I imagine it would depend on what part of the wiring is bad, I seem to remember Verizon's responsibility stops where the wire first terminates inside the building.

I guess I could test that with a old phone and a couple bare wires. Today the phone is fine now though, go figure.
 
To be sure you would need a test set and test is before the system and see where the static starts or stops.Then you could tell who's problem it is.
