Doh, my bad - I've looked into osmo-pcu instead of osmo-bts. You're
absolutely right, thanks!

As far as I've understood continuous TA procedure I've got to have PTCCH
activated in both directions. The problem is that I have troubles
locating the code which triggers the activation above.
from
osmo-bts/src/osmo-bts-sysmo/oml.c:
static const struct sapi_dir pdtch_sapis[] = {
{ GsmL1_Sapi_Pdtch,»····GsmL1_Dir_TxDownlink },
{ GsmL1_Sapi_Pdtch,»····GsmL1_Dir_RxUplink },
{ GsmL1_Sapi_Ptcch,»····GsmL1_Dir_TxDownlink },
{ GsmL1_Sapi_Prach,»····GsmL1_Dir_RxUplink },
#if 0
{ GsmL1_Sapi_Ptcch,»····GsmL1_Dir_RxUplink },
{ GsmL1_Sapi_Pacch,»····GsmL1_Dir_TxDownlink },
#endif
I don't know exactly why it is commented out, probably because itw as
simply not used at the time?
