Hello everybody !
Can somebody tell me the technical difference between analog phone lines
(PSTN) versus digital ones (ISDN or aDSL) ?
Is there any way to distinguise them with an electronic device ?
I've heard of these digital phone line tester but I'm not sure if this is
the one I'm looking for to build.
Any ideas ? Many thanks, in advance
