Reply To: RF Loop test fault in Ericsson RBS2206

francis nyarkoh

I have a problem “RF loop test fault” with RBS2206 and one TRX was blocked. I’ve replaced dTRU, DXU, Y-link, Rx & Tx cable, but the problem still not resolved yet.
Does anyone know the principle of “RF loop test”? so we can know which part of RBS is damaged.
Please help..
