The Osmocom community have a retro networking project, with projects
including TDM over IP.

https://osmocom.org/projects/retronetworking/wiki/

They have also created an open hardware USB E1 interface that can be
used with the aforementioned, as well as with older GSM base stations
which implement Abis over E1 (which you can then operate with the
Osmocom CNI software stack).

There's also Osmocom-Analog, if your interests extend to retro cellular.
