    Hi all,

    I am also experiencing this kind of problem with RBS 2206. I have already tried replacing CDU, DTRU and DXU but still have high DCR caused by high T_DR_BQ_DL

    also, the problem started since commissioning and integration.

    this is in In-Building Coverage

    How much traffic does that RBS have?
    How many drops are occurring?
