    Last option left is to check feeder connection at the antenna end. Do you see any alarm other than this in that particular sector???? any diversity related alarms?????

    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.

    Thanks!

    plzz follow some points….

    1.swap the feeders of A sector with B sector.then see fault moves in B sector or still in A sector.

    2.if fault moves in B sector then there is problem in the upper part means may be jumper,feeder,anteena.

    3.do this then tell me…
