Description

This testcase was added by me back in 2019 and was known to pass until recently:

commit 51cbc104c6c060f1f495f7f0b2d4795dbf4c5ea9
Author: Vadim Yanitskiy <axilirator@gmail.com>
Date:   Mon Apr 22 06:37:30 2019 +0700

    BTS_Tests.ttcn: add TC_pcu_ext_rach_content() for 11-bit RACH

"BTS_Tests.ttcn:5881 : Timeout waiting for RACH IND" 
      BTS_Tests.ttcn:8982 BTS_Tests control part
      BTS_Tests.ttcn:5881 TC_pcu_ext_rach_content testcase

I already tried to investigate why this happens and it looked like fake_trx.py is not properly reset by one of preceding TCs, so the Access Bursts are dropped by L1SAP.
