DSL is by design placed outside the human auditory range (also why it has such limited range between home and exchange). As such, you are better off thinking about it like the analog part of most any wired network.
ISDN by contrast puts a digital signal where the PSTN analog signal normally is (iirc).
- twic 9y agoADSL still pretty different to something like Ethernet - not that i understand Ethernet terribly well either. Ethernet is baseband: it really is a digital on-off signal, with Manchester encoding, 8/10 encoding, 64/66 encoding, etc. ADSL is broadband: there is modulation into phase and frequency patterns. Mind you, 8/10 encoding is amazing as well, and a good explanation of that would be well worth a read for this audience!
