    To Pix:
    Thanks for you reply. But I just want to know how the 4 SDCCHs are sufficient for call initiation if all the 7 subscribers are trying to access the network. I think that, at first only 4 people will be given access to the network and the when they are latched onto TCH, the same alloted to the remaining..is that true? Please tell me whats the criteria in deciding the number of SDCCHs to be alloted for a given carrier?
    To Yogesh:
    I am not facing any problem yaar. Just want to know the above details..Thank you

    hi vijay,

    there is no theoretical rule to define the ration SCCH / TCH, it all depends on your subscriber behaviour (amount of SMS especially). The rule of thumb is : 8 SDCCH for 14 TCH.

    In some countries, the amount of SMS is so high that you need 3 or 4 SDCCH timeslot (24 to 32 SDCCH) in order to cater for the SMS trafic.

    Anyway, you can just start your cell with 4 SDCCH and check the sDCCH congestion. Then, accordingly adjust the number of SDCCH if you measure SDCCH congestion…

    Regards,
    Xavier

    Hi,

    I would like to kinow something about the number of circuit breakers (MCB/MCCB)that are used inside a BTS. Do all the manufacturers incorporate the same number of circuit breakers or does it change..??

    A brief understanding of their current/voltage range would be useful as well.

    my mail id is: ashutosh.kumar1@evalueserve.com

    do you know? Why we get not the alarm code on the Nokia WCDMA BTS manager. (Nokia Supreme Node B)

    Normally it indicated the “the door is open” or any alarm code if the Transceiver or WPAB is faulty.

    I haven´t found where can i activated!!

    hi, am tibco.engineer
    .
    Depending on the equipment manufacturers,we have different configurations ranging from 2TRxs to even 24TRxs in one BTS.It should be noted that the higher the TRXs the higher the capacity of the Cell.Combiners are used to combine the Transmit signals to a common Antenna for transmission and Distribute the receive signals to the various Tranceivers.

    Hi Parsa79,
    for Siemens technology: do you mean Priority Layer (PL), Priority Layer Neighbour Cell(PLNC), and HIEC which enabled this feature? Than I could help you. PL = 5 is higher than PL = 10. PL is in the range 1 up to 15.
