If it dials O.K., try pressing # and see if it turns on the DTMF pad. You could have pulse dial on outside calls enabled, and that would keep the keypad in pulse mode until it's told to send tones.
This is really only a guess. The type of dialing is programmed in CO trunks and it's possible it's been set to Call Blocking! It is designed to send pulse only and block the audio of DTMF so the CO won't get confused. You might start with changing the Type Dial to DTMF and test. If that doesn't work, try Pulse and test. Last, if that doesn't work, you will need to keep call blocking and try the # after dialing.
Please comment back if it does or doesn't work. We don't see much pulse dial around here.
Hi ,The 9105 PTU Takes the ships mains from the PCT 9106 PCB make sure you have the supply form the PCT board ready which is a protection circuit ,should you have an overload from the modulator pcb then the pct board shall inhibit the supply to the ptu 9105 ,so here is what you have to do ,disconnect the HV 330 volt going to the modulator pcb and then switch supply on ,ensure your fuses are all fine .fond [email protected]
