  • Subject changed from 11 bit rach is not supported in osmo-trx to Extended (11-bit) RACH is not properly handled

It was noticed that with both patched OsmoTRX and OsmoBTS, OsmoPCU does receive
extended RACH bursts, and even recognize them as extended, but doesn't handle properly.

The phone constantly sends RACH bursts, but a PDP Context is never being activated :/

That's exact duplicate of earlier #1548 - let's move all the discussion there to prevent it from spreading over several tickets.
