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.
