    hi sairam,
    pls check these: 1.parameter RDIV should be ON.
    2.it might be possible only RX Cable swap from other sector.
    3.check all cable inside the BTS one point to other, it may be swap.

    Reason:this alarm can come when diversity may go beyond 5 So any of the cable inside BTS Gt. swapped.

    “What might be the reason of 7715 CONTINUOUS RESTARTS OF BCF”

    Because your BTS reset 3 or 4 times in less than 5 minutes.
    I don’t remember exactly but too reset in little times.

    It is not a critical alarm. You can reset by ZEOR:bcf:n°alarm;

    Thanks Patrick, the cause of continuous restarts was unstable voltage… 🙂

    Thank you so much for the suggestion.

    I got another question.

    Is the RRI of Metrosite, compatible to Ultrasite? Can u use that module directly to Ultrasite? By re-mapping it at Traffic Manager?

    Many thanks.

    We don’t have RRI for ultrasite. We have FXC ET1/T1.

    4 PCM in/out

    On traffic manager
    – Select unit (FXC or RRI)
    – select interface (PCM 1 …4)
    – place Tch, TRXsig, OMUsig, Edap, on your abis allocation for BTS.

    (Warning: Metrosite don’t work with hubmanager.)
