2024-03-06: RetroNetCall on decoding Fax G4 protocol traces

Added by laforge about 1 month ago

We're happy to announce the next incarnation of RetroNetCall, the retronetworking oriented spin-off of OsmoDevCall

This time, laforge will give a brief look decoding Telefax G4 protocol traces, as he recently acquired one of the few G4-capable fax machines, a Canon_FAX-L260i. G4 is the digital-only version of Telefax that works without a modem, directly over the 64k ISDN B-channel.

We'll look into the ITU-specs of Group 4 Facsimile Service as well as at an actual B-channel protocol trace taken a few days ago.

When: Wednesday, March 6, 2024 from 20:00 CET

Time Topic Who
