how many E1 can supported 32 TS (4,6,4° BTS configuration19th December 2006 at 11:35 #46308MaheshGuest
if u use combined BCCH
then u have 7 TCHs
then minimum 7 full rate calls
maximum 14 half rate calls
then no of calls vary 7 to 14
if u use uncombined then one time slot for BCCH one for SDCCH
then u have 6 free time slots for TCH
then u can make 6 minimum full rate calls
and 12 maximum half rate calls
then no of calls vary 6 to 128th May 2014 at 08:31 #46309AnuragGuest
Wants to know the possible number of calls for 1TRx8th May 2014 at 08:40 #46310TanujGuest
The number of calls that can be handled by a TRX depends on the number of channels defined on it, if all 8 channels are defined as Full Rate TCH then 8 calls and if 8 Half rate TCH then it can take 16 calls at one time.

Why 86 call can handle from BSC at a time.Can you please explain5th October 2015 at 19:03 #46313VKGuest
Currently there are features which support quad rate calls in the system ie 4 simultaneous calls at one time slot.
in Ericsson : it’s known as VAMOS feature and in Nokia : it’s known as OSC feature.
Ex: 1 TRX=8 tsl
using combined mode we have 7 TCH TSL.
Total Voice calls supported by TRX= 7*4=28 calls simultaneously.

What is half rate and full rate in Trx configuration?18th March 2017 at 07:02 #46316LEMAUREGuest
Hello Arinze Chidi!
HR/FR is a multiplexing mechanism on timeslot taken by the BSC in other to fit with capacity requirement. This rate change is guided by parameters that enable the BSC to take decision on the rate to set for new incoming calls in a particular cell.
Now half rate is 2 users multiplexed on a single TS every frame and each of them haS his SACCH channel on frame 12 and 25 for MR report purpose, across multiframe2630th March 2017 at 13:28 #46317Kalyan BorgohainGuest
