direct-phy: fix handle_ph_ra_ind(): handle PH-RA.ind on PRACH SAPI In [1] I restricted L1 SAPI of PH-RA.ind to PDTCH and PTCCH, and this seems to have caused a regression reported in [2]: DL1IF ERROR sysmo_l1_if.c:251 Rx PH-RA.ind for unknown L1 SAPI PRACH I assumed that PH-RA.ind belonging to a Control Acknowledgement message (in format of 4 Access Bursts) would have PDTCH SAPI, while apparently it's actually arriving on PRACH.

This repository contains a C/C++-language implementation of a GPRS Packet Control Unit, as specified by ETSI/3GPP. It is part of the Osmocom Open Source Mobile Communications project.
The Packet Control Unit is terminating the Layer 2 (RLC/MAC) of the GPRS radio interface and adapting it to the Gb Interface (BSSGP+NS Protocol) towards the SGSN.
The PCU interfaces with the physical layer of the radio interface. OsmoPCU is typically used co-located with the BTS, specifically OsmoBTS. For legacy BTSs that run proprietary sotware without an interface to OsmoPCU, you may also co-locate it with the BSC, specifically OsmoBSC
The official homepage of the project is https://osmocom.org/projects/osmopcu/wiki/OsmoPCU
You can clone from the official osmo-pcu.git repository using
git clone git://git.osmocom.org/osmo-pcu.git
There is a cgit interface at http://git.osmocom.org/osmo-pcu/
We provide a user manual as well as a vty reference manual
Please note that a lot of the PCU configuration actually happens inside the BSC, which passes this configuration via A-bis OML to the BTS, which then in turn passes it via the PCU socket into OsmoPCU.
