not really sure Larry.
i have an old rotary phone in the garage addition, and it works, so i'm thinking i could get my pay phone to work if i hooked it up.
i know one thing. when comcast hooked my phone service up, after MANY return visits to get it to work correctly, i just re-did ALL their work myself, and the phones have worked flawlessly since !
the MAIN problem with their current installations rely on "scotch-lok" type connectors, the kind that you squeeze together piercing the insulation to connect the wires. that results in "iffy" connections, just like using these style connectors in automotive wiring.
anyway, back to the original programming.
one of these days, i'll dig out my pay phone and try it.
one thing that was pretty neat when my phone company buddy gave it to me, was the coin box key came with it ! he said i could make a fortune with that key, as it was a master and could open any pay phone !
well, needless to say, since all the pay phones were being removed from this area, [the reason i got this one in the first place] no fortune was to be had by me !
