osmo-pcu implements the RLC and MAC layers of GPRS as well as the functionality of a PCU.
It implements a custom L1 interface that can be used with [wiki:osmo-bts], and also with
an unofficial version of OpenBTS.
Towards the SGSN, the BSSGP and NS protocols are implemented over UDP/IP. It has only been tested with
[wiki:OsmoSGSN] so far.
