    Hello again,

    Can any of you pls explain why do we have Prep fails on BSC level in Alcatel BSC, as i know prep fail normally occurs when ever DCS cabinet is down but it is for cell level, but i could not figure out why it happened on BSC level, as there is no alarm on any of the ater mux,nor any of the BSC card, pls help



    During to assignment request
    the prep fail can dedicat in preparation phase
    if the resource not available in the BSC (congestion)
    if resource available next step is channel activation ( if channel activatation fail = system failure)

    First check TCH congestion or TCH block persist?
