Hello,
You were right it's an old machine, but it takes 4 wires to for each station to work, All the stations working fine, (I tested them one by one) and also the CO lines, but they are on pulse mode, I can't get them to work on Tone mode, any clue how to do that?. Also the SLT telephones are working OK, but they don't communicate with each other, I could hear the tone, but I can't dial from them. Can anyone please tell how to get to program mode on that machine?
Thanks a lot.
Musa
