did you test sectors with crossing equipments? (tru,cdu,feeder,antenna,rx jumps)
this alarm appears at least 50 minutes.

You might be missing RX antenna. Please u can see at OMT radion faults that u miss the RX antenna. if u attach antenna i hope alarm will go off.

Hi Toby,
do you have VSWR alarm too?
Toby Guest
I’ve checked the antenna and all of them are connected. I just changed the Rx diversity of the antenna to Azimuth and the alarm cleared.
I’m hoping it wont come back cos the only option i feel i have now is to change the CXU.

do a test call around and check maybe you’ll pickup the wrong bcch on the wrong sector.. then rewire or redo jumpers

Check / change the RX cables, may be with another sector, so that when the alarm comes in again, you know why.
Remake the connectors at jumpers and feeders at both ends.

change the RX cable from sector to another sector and try to remake sure connector and jumper to Remove VSWR alarm

It was the CXU…I changed the CXU and the fault cleared permanently…

Dear sir,
I am facing the problem of antenna branch alarm-Branch-B in all sectors.
It was found vswr values normal then also vswr alarms are pinging in my 10 sites on ericsson 3g RNS6202.
Kindly guide me for alarm removal.
