Re: Pulse (Loop Disconnect) to Tone (DTMF) Converter?
The device would have to count the pulses then activate a DTMF tone. I am not sure what time interval window between DTMF tones is acceptable to the PSTN. In other words, if you dialled a nine, this would create quite a delay while the circuit counted the pulses then generated the DTMF tone. I'm just guessing about this, and have never tried it though. I have seen DTMF tone chips and pulse dial chips but never a pulse to DTMF conversion chip. Maybe someone with direct experience of BT networks would be able to help.
