Harald Welte d67966b43e ipa_keepalive: Make FSM a bit less quiet 
Let's make sure we log meaningful log messages whenever an IPA keepalive
FSM is started, stopped or if it times out.  This allows the user to
observe whether IPA keepalive is actually enabled (using what timeout),
and also to learn why exactly the connection was dropped.

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.
