trau_pcu_ericsson: also support ER_UL_CHMOD_NB_UNKN in 16k mode.

With EGPRS Ericsson introduced an "UNKN" demodulation mode for normal
bursts. This would instruct the CCU to listen for GSMK and PSK
modulation simultaniously. For 16k there is only GSMK and there would be
no need for such a mode. Lets support it in the API anyway in order to
simplify API usage. When the caller selects it, we just use
ER_UL_CHMOD_NB_GMSK then.

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.
