Checklist

  • BTS->PCU: TIME_IND
  • BTS->PCU: DATA_IND (PDTCH / PTCCH)
  • verification of PCU-originated DATA_REQ arrival on Um/MS side
  • existing tests: "FIXME: how to check this wasn't actually sent and didn't crash BTS?"
  • verification of INFO_IND data like timers, CS-mask, mcc/mnc/lac/cid/rac/nsei/bvci
  • verify that second connect to socket gets discarded while first survives
  • PCU->BTS: PCU_IF_MSG_TXT_IND -> OML ALERT
  • PCU->BTS: DATA_REQ on PCH
  • BTS->PCU: RTS.req, for all lchan on all ts on all TRX
