Hi PIX & Bijoy…
Can u please share me how many site we can attach to one nesi(we are using 1 logical pcu2_D).Here we have to config one site with max 9 number of GTRX and EDAP for 3 channel.CDED 17%,CDEF 34%,CMAX 100%.NSEI bandwidth 640 kbps.Please teach for the calculation detail.
as you know that PCU2_d can handle 256 channels (16kbps) the utilization should be 70% that means 180 channels so your calculation as:
=no of sites *no. of cells *CDEF*(channels support GPRS in TRXs)+EDAP channels (16kbps)
for example in your case
S3/3/3 :all TRXs enabled GPRS and channels =3*8-BCCH-2SDCCH=24-1-2=21
so we have 21 channels in TRXs enabled GPRS per cell and we have 3 EDAP timeslots (64Kbps)=4 (16kbps)*3=12
so per site
1 pcu can handle sites
NOTE:i recommend to increase EDAP to 6 timesloats
