    Hi all
    SDCCH Drop Due to other reason has been increased in some sites which they are near to one military base (there is lots of antenna and radar equipment on this base),probably there is no external interference because the ICM band is ok,what do you think?have you faced same problem,it would be appreciated to share ur idea.

    Well check your hourly trend and conduct Spectrum analysis on UL and DL during the effected intervals.. compare it with a normal situation.Issue might be due to some link.. effecting DL only for that UL IOI stats dont show degradation.
    Or check for ABIS trace / Probe based analysis and check for SD_Failures

    Change cable or connecter and see…Sometimes they are not shown as alarms.
