Philipp Maier 122a66da2e trau_pcu_ericsson: add testvectors for MCS1-MCS8 
The testvectors were obtained manually from the uplink of an
Ericsson RBS RUS 02 B3. The TRAU frames were selected so that they
contain valid MAC blocks from live GPRS traffic.

libosmo-abis - Osmocom Abis interface library

This repository contains a set of C-language libraries that form the A-bis interface library of Osmocom Open Source Mobile Communications projects such as OpenBSC / OsmoBSC.

Historically, a lot of this code was developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.

The libosmo-abis.git repository build multiple libraries:

  • libosmoabis contains some abstraction layer over E1/T1 and IP based ETSI/3GPP A-bis interface. It can use mISDN and DAHDI as underlying driver/hardware.
  • libosmotrau contains routines related to A-bis TRAU frame handling

GIT Repository

You can clone from the official libosmo-abis.git repository using

git clone https://gitea.osmocom.org/osmocom/libosmo-abis

Documentation

There is no Doxygen-generated API documentation yet for this library. It would be great to some day have it, comparable to libosmocore.
