Sector Rx path imbalance:

1st You have to understand why you have the alarm :

– The rx-path imbalance is caused when rx path A takes >10% more traffic than rx path B. This can be an issue with the radio if there is more than 1 transceiver on that sector. If there is only one transceiver than it means that this radio is not built properly in the BSC and needs to be corrected.

Run in your BSC the Next commands:

***********Run below section to halt/block TRX and remove ANTB to clear RxImbalance alarms************************
rlstc:cell=SITENAME, state=halted;
rxbli:mo=rxotrx-TG-a,subord,force;
rxese:mo=rxotrx-TG-a,subord;
rxmop:mo=rxorx-TG-a;
rxmoc:mo=rxorx-TG-a,BAND=GSM1900,RXD=A;
rxmoc:mo=rxorx-TG-a,ANTB=” “;
rxmop:mo=rxorx-TG-a;

***********If RXD=A and ANTB=Blank Then proceed to Reload and UnHalt sector proceed to below commands************************
rxesi:mo=rxotrx-TG-a,subord;
rxble:mo=rxotrx-TG-a,,subord;
rlstc:cell=SITENAME, state=active;
rxmsp:mo=rxotrx-TG-a,,subord;
rxmop:mo=rxotrx-TG-a,,subord;
rxcdp:mo=rxotg-TG;

SITENAME = your site ID name. ie: SL1234A
TG-a= The “TG” of your site in the BSC and “a” for the sector thst has the alarm : ie: Alpha=0, Beta=2, Gamma=4
Check the alarms in your Site (TG) and the RX path Imbalance should be fixed it.

Good luck !
