Hi
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.
