Re: OL not taking any call
Hello Jitendra,
I am interested to know whether this problem is spread network wide or on some few cells?
But again if no traffic is picked how would there be any dropped calls?
Please provide more details so your problem can be well understood and working solutions be given out.

Re: OL not taking any call
Hi,
Do you mean that there's no traffic at all on 1800? If yes, please let the Field engineer reset the DXU of the 1800 RBS. There might be a synchronization problem on the TG. Let hi check also the OVP connection. The termination from DXU-OVP should be connected to 100-120ohm balanced OVP.
Parameter wise, please also check FBOFFSP, don't set this too high..recommended is between 3 to 6.
