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). https://osmocom.org/projects/e1-t1-adapter/wiki/IcE1usb There's also Osmocom-Analog, if your interests extend to retro cellular. http://osmocom-analog.eversberg.eu/ Andrew
