Does anyone know how to clear abis problem on BTS Ultrasite? I am experiencing an Abis Problem only on sector 2. I’m pretty sure that the the antenna and cabling was all good. We already try to swap TRX’s and combiner to isolate the problem. We already changed the Branching Table. We also done 24 Hr. BER Testing and Sync Test on Radio Trs.
Thank you all guys in advance
