First success getting frame-sync + decode of V.110 data from raw ISDN B-channel traces. Why? Well, GSM has this feature called CSD (circuit switched data), and we want to add that to #osmocom. And GSM CSD is a derivateive of ITU-T V.110 for ISDN. Also a good excuse to talk about ISDN B-channel protocols in next #retronetworking #osmodevcall https://fosstodon.org/@osmocom/109433797054725269

Well, apart from that both seem to use the same kind of 1 cable as attack vector, I'm watching
