gsm_08_08: define GSM0808_SCT_EXT (separately) As per 3GPP TS 48.008, section 3.2.2.103, the "Codec Type" field may contain either a certain 3GPP Speech Codec Type directly (4 bit value), or the so called "Codec Extension" = 0xFh, in which case the real Codec Type follows in the next octet as "Extended Codec Type". CSD is such an example, the encoding is defined as follows: 8 7 6 5 4 3 2 1 +----+----+----+----+-------------------+ | -- | PI | PT | -- | 0xFh | +----+----+----+----+-------------------+ | Extended Codec Type (CSData) | +----+----+-----------------------------+ | R2 | R3 | | +----+----+-----------------------------+ CSData is coded with 0xFDh or '1111 1101' (0xfd). Let's have the "Codec Extension" value clearly defined in the header file, but intentionally separate from the other GSM0808_SCT_* values.

This repository contains a set of C-language libraries that form the core infrastructure of many Osmocom Open Source Mobile Communications projects.
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.
There is no clear scope of it. We simply move all shared code between the various Osmocom projects in this library to avoid code duplication.
The libosmocore.git repository build multiple libraries:
The official homepage of the project is https://osmocom.org/projects/libosmocore/wiki/Libosmocore
You can clone from the official libosmocore.git repository using
git clone https://gitea.osmocom.org/osmocom/libosmocore
There is a web interface at https://gitea.osmocom.org/osmocom/libosmocore
Doxygen-generated API documentation is generated during the build process, but also available online for each of the sub-libraries at https://ftp.osmocom.org/api/latest/libosmocore/
