hi,
my question is
how many simultaneous calls can be handled by a single transceiver of a BTS in a GSM network.
depends on what kit you use a nokia ultra will allow 7 TCH with 1 combined SD&BCch
For Full Rate speeach codec:
Up to 7 TCH.
For Half-Rate: – up to 14.
how many E1 can supported 32 TS (4,6,4° BTS configuration
Hi rajababu,
Depends,
if u use combined BCCH
then u have 7 TCHs
then minimum 7 full rate calls
maximum 14 half rate callsthen 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 callsthen no of calls vary 6 to 12
Wants to know the possible number of calls for 1TRx
Hi Anurag
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.

Tanuj Royneed to know about trx channel and xpic link configration
Why 86 call can handle from BSC at a time.Can you please explain
Hi,
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.
Regards
VKis the number of Time-slots the same with the number of Channels in a TRX?
How many number of Time-slots in a TRX
How many number of channels in a TRX for both full-rate and half-rate??
How many number of channels in an E1?
How do you explain the relationship between an E1 and a TRX interms of channel equivalent?
What is half rate and full rate in Trx configuration?
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 multiframe26RAACH degrading suddenly :
What are the check points ..
Please provide the solution for rectificationplz suggest how many call transmits and receive in one time in one TRX.
How many TRX used in one sectors and how many TRX to be used in one E1.
