    7601 appears due to DAC value drift,
    It has many causes.
    1-BSC Clock problem.
    2-Transmission problem(Unstable)
    3-BOIA faulty.

    Action.
    Kindly check BSC clock oscillator value,if Clock,Transmision and BOIA are OK,

    then Adjust DAC value on BTS site 2048 and send it to BTS through BTS manager.
    after this refresh OMU by MML.

    It should be clear.
    Some time this problem appears on many sites connected one HUB.

    Thx

    Hi, i have an alarm “Timing accuracy not guaranteed to be within configured LTE limits for loose HSFN” using TOP-P, this is Phase Syncronization. I am the clock guy (TP4100 Microsemi inside CLARO NETWORK) but i am helping to the BTS guys to troubleshoot it.

    Any idea what is coming on with this site?
