Fail the compilation if TCP_KEEPIDLE, TCP_KEEPINTVL, TCP_KEEPCNT or
TCP_USER_TIMEOUT are not defined.

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

There is a web interface at 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.
