Sorry, I am rusty at this. I do it once in a blue moon and in simpler arrangements.
I am trying to ring out cables in an OLD 3 story building. They have loads of 25 pair Telco cables and 99% are unused. Trying to get from the 3rd floor to the basement to bring up a single POTS line. In 1 closet, I found 4 separate patch panels, 1 linking to another. I have a tone set line this:
mine is much older but works fine (I think). I have a regular phone that I use as a butt set.
If the tone box is making tone, and I clip it to the regular phone, I would have thought I would hear the hi /low tone in the phone? But that doesn't seem to be the case. If I clip the tone box on a pair with dial tone, then the phone will hear the dial tone AND hi / low. Does the tone box not make enough signal to hear on a regular phone?
All that said, how do you find the pair in a 25 pair cable that you have the tone box hooked up to? I have a strong idea of the pair from the loudness of the toner, but several wires pick up the tone from the wires running parallel in the building.
