New Retronetworking Project: Software-Defined Uk0

Added by laforge about 2 months ago

Osmocom developer jolly has started a new project for implementing the central-office side of the ISDN U (Uk0 in Germany) interface using a sound card with 192kHz samplerate.

Using this setup, you can connect an ISDN NT for BRI (NTBA in Germany) to your sound card, and provide ISDN services via mISDN.

Some basic information about a first proof-of-concept can be found at Software_Defined_Uk0; stay tuned for more information.

There is no real documentation yet on how to reproduce this, but code can be found at https://gitea.osmocom.org/retronetworking/uk0 (SDR PHY for Uk0) and https://gitea.osmocom.org/cc/osmo-cc-misdn-endpoint/src/branch/jolly/uk0 (mISDN port to make use of the former).
