I have the same problem with GEMINI cells . Cells are having high SD Drops . Cells have SDCCH in Hopping TRX and I didn’t tried to move it to BCCH TRX . By doing that will it improve the SD Drops . The main reason coming is under SDCCH_RADIO_FAIL
i have interrupted cell alarm for long time ,, come of these cells i have checked them have problem on Trx contian control channel “BCCH” ,, I am thinking can change the channel configuration and transfer BCCH channel to other TRX ???
