2023-03-15: Circuit Switched Data in GSM

Added by laforge 18 days ago

we're happy to announce the next incarnation of OsmoDevCall.

This time, laforge will be presenting on Circuit Switched Data (CSD) in GSM

CSD is the mechanism by which circuit-switched data calls can be made over classic GSM/2G (and later also UMTS/3G) networks. They resembled the modem call of circuit-switched networks, but of course no voiceband modem is involved.

For more information, see our CSD wiki page.
