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?
I am not facing any problem yaar. Just want to know the above details..Thank you6th November 2006 at 14:36 #39591AkashGuest

Installation & Commissioning of MW & BTS Equipment for GSM & CDMA:
Could you pls send me mannual or document. My mail id is:email@example.com November 2006 at 15:14 #39593pixGuest
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…

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.

Hi to all,
E1 has a 30 channel and T1 has 24.
For ericsson equipment using E1 it had a 2.5 timeslot for TRU(Unconcentrated)LAPD.
My question is for T1 carrier how many time slot per channel for one TRU.
Please clear me about this.

How is possible to see le alarm code on the WCDMA BTS Manager og the node B supreme.21st November 2006 at 11:42 #39597GAMGuest
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.

Follow up on the question of BTS. Waleed, thanks for your reply. The BTS is a Siemens BS240. Also mention something about DULNA & VSWR And duamco configuration. Thanks

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.26th November 2006 at 04:14 #39602parsa79Guest
i whould like to know in siemens bts what is the parameter of priority between 900 and 1800 bands?
the value of the above parameter?
thanks alot26th November 2006 at 21:25 #39603TomarGuest
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 15.27th November 2006 at 12:07 #39604parsa79Guest
