    Hi I am working in Nokia System support team Pune.

    I have one querry regarding DAC value. First of all the meanin g of the same its desired values to be set.

    The drift inthis value is given by the alarm “difference between PCM and base station frequency reference”

    Now if 3/4 of the sites in 1 BSC are having this alarm should there be any common reason?

    Hello:

    Jayesh: It could be a transmission problem have you check if there is a common path?

    Madhav: the alarm configuration for ultrasite is made from the BSC using the EFX command, I thik is the same with the metrosite.

    Best regards

    You can see FAR END but you must have this good version of software.(to see alarm, rssi, change tx power ,…)

    check this: maintenance – software – view.

    program ID, CHECK Active version.

    The more indice is high, the more is better.

    ODU =>
    P55040.01 G1
    P55046.01 C1

    IDU
    P55230.01 A8
    P55234.01 C1

    RRIC
    P55295.01 A2
    P55298.01 C2
    P55285.01 B2

    if the versions are lower than my example. You should make an upgrade.

    Warning: certain versions are not compatible between them

    Jayesh Satghare: The dac value is how you are able to adjust your 13Mhz clock on your BOIA card on an Ultra site or a BCFA on a TalkFamily. Inorder to get this set correctly you must use a freq counter. This dac value will be different on everysite so don’t try and set all BTS’s to the same dac value. Once you have your freq counter dialed into exactly 13Mhz make sure you click on set as current and then save current permanently. This value will however drift a little to reallign itself with the frequency on your T-1. If it is drifting dramatiaclly check your bits clock in your BSC.

    In Nokia Metrosite BTS the DAC value was initially set as 2000 with +- 200 tolerance. Unfortunately, the DAC value keeps drifting down.

    Does anybody have an idea why? Maybe the initial value is not right?
