We calculate traffic in terms of Erlang
Take the total nos of TRX in to consideration,Remove the BCCH time slot and we have got 7 ts in one carrier .
Take the equivalent erlang in the TS
Take erlang per subscriber
divide the total erlang by erlang per carrier(depending on the carrier)
And lo u get the max subsccriber(max voice traffic)in the carrier25th July 2004 at 07:18 #34461Mohammed NayeemuddinGuest

I want to improve my knowledge of telecom technology and request u experts to guide me on the same
where can i get these information on CDRs of various switches?
Where can i find the replies to the queries? I hadn’t seen much on this page

In respond to your question,of howmany voice calls can be made in one traffic channel,I will tell you 7 calls can be made.Following the GSM principles of 8 TS,this means 7calls can be made while one TS is left for signallisation.14th August 2004 at 06:43 #34468Mohammed NayeemuddinGuest
Mr Vouyf ngwo
Thankyou v much for your response for my question.One thing i did’nt uderstand that in one traffic channel there will be 24 TDMA frames and each TDMA frame having 8 times slot ie 8 bursts and each lasts for .577 ms.so if want to know ,how many calls can be made in one traffic channel will it be 7 or 7×24.
second thing accoding to Mr promod nair explanation on 22nd july 04,he has shown one procedure. consider total no of TRX then remove BCCH, take eqvivalent erlang in TS,then take erlang per subscriber then divide total erlangs by erlangs per carrier to find no of vioce calls can be made in one traffic channel at a time.
Going through all this, can you give more clear explanation, that how can we find the total nuber of voice calls we can make in one traffic channel at a time.29th August 2004 at 11:37 #34469yacineGuest
