At the moment the PCU has no way of knowing with which BTS model it is used with. However, some BTS models may require slightly different behaviour by the PCU, depending on which BTS model is used. So, lets add an additional bts_model field to struct gsm_pcu_if_info_ind in order to convey the exact BTS model to the PCU.

osmo-bsc - Osmocom BSC Implementation
This repository contains a C-language implementation of a GSM Base Station Controller (BSC). IT is part of the Osmocom Open Source Mobile Communications project.
OsmoBSC exposes
- A over IP towards an MSC (e.g. OsmoMSC): 3GPP AoIP or SCCPlite
- Abis interfaces towards various kinds of BTS (osmo-bts, sysmobts, nanoBTS, Siemens, Nokia, Ericsson)
- The Osmocom typical telnet VTY and CTRL interfaces.
- The Osmocom typical statsd exporter.
- Cell Broadcast Service Protocol (CBSP) towards a CBC (Cell Broadcast Centre, such as osmo-cbc).
- Lb interface towards a SMLC (Serving Mobile Location Centre, such as osmo-smlc).
Homepage
You can find the OsmoBSC issue tracker and wiki online at https://osmocom.org/projects/osmobsc and https://osmocom.org/projects/osmobsc/wiki.
GIT Repository
You can clone from the official osmo-bsc.git repository using
git clone https://gitea.osmocom.org/cellular-infrastructure/osmo-bsc

Documentation
User Manuals and VTY reference manuals are [optionally] built in PDF form as part of the build process.
Pre-rendered PDF version of the current "master" can be found at User Manual as well as the VTY Reference Manual
There also is an Abis reference Manual describing the OsmoBTS specific A-bis dialect, as well as a CBSP Reference Maunal describing the level of CBSP conformance.

History
OsmoBSC originated from the OpenBSC project, which started as a minimalistic all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached maturity and diversity (including M3UA SIGTRAN and 3G support in the form of IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one approach to fully independent separate programs as in typical GSM networks.
OsmoBSC was one of the parts split off from the old openbsc.git. Before, it worked as a standalone osmo-bsc binary as well as a combination of libbsc and libmsc, i.e. the old OsmoNITB. Since the standalone OsmoMSC with a true A interface (and IuCS for 3G support) is available, OsmoBSC exists only as a separate standalone entity.
OsmoBSC-NAT is a specialized solution to navigating RTP streams through a NAT. (Todo: describe in more detail)
