Hello,
I was just wondering if anyone has used GNURadio for any non-radio
applications, specifically phone line modulation/demodulation.
It shouldn't be too difficult to design a daughter board for the USRP to
sample phone line voltage (with an appro

Yeah, just one: 47 CFR Part 68. As in FCC regulations on items that can be
connected to the PSTN. A part 68 interface card that could be used to
provide an interface to an LFRX/LFTX pair would be ideal.
Marcus can elaborate, being that he is employed in that field.

Hello,
I was just wondering if anyone has used GNURadio for any non-radio
applications, specifically phone line modulation/demodulation.

course). Afte
