1.How to clear the RX Path alarm permanently?
(Normally we checked the physical condition, Jumper Cable conditions, bending shape, if we can’t also replaced by RRU and new Jumper cables but not cleared permanently).
2.How to resolve the RX Diversity lost alarm?
3.Why does appear the VSWR limited exceed alarm when using(U900+2G) at the one RRU?
Hi Thant Zin Htun,
Check MHA or TMA if you’re using them. If yes, remove them and see if alarm disapears. If MHA is Ok, replace RRU. Is that happening in one or all sectors? What’s the vendor?
