if alu experts are correct, then it means the cell is shutting down the TRX’s during electrical failures. In this case, only the BCCH is up. Try relocating one of the SDCCH ts to the BCCH TRX…
Could you share with us:
SDCCH Traffic duration avg
Traffic Split (SDCCH Usage = MC02x counters) LU, IMSI DETACH, MOC, MTC, SMS, etc.
All these indicators per hour for one day, please.
