Listmembers, We are doing in-house continuity compliance testing to Part 68, and one of our products is a voice-band modem (V.34). Normally these modems will shut off if they don't detect another modem at the other end. Does anyone have any way of getting this type of modem to output handshaking and DTMF tones for signal power measurements without having a second modem connected? It uses a Rockwell chipset.
Could I use two modems back to back? In that case, could I measure the voltage and the impedance of the line with a bridge to calculate the power? Any help would be VERY appreciated. Regards, David.
