In ericsson, all the signalling(BCCH, SDCCH, PAGING, FACCH, SACCH) go through separate timeslots on the abis. That is why concentration is done. In that sense, it would be incorrect to assume that each TRX uses 2 abis timeslots.
In my network, each site is typically 4/4/4. We have 2 EDGE timeslots per cell,2 SDCCHs per cell and a CONFACTOR of 4. Yet we use only one E1 per site.
Per NJ’s calculation, this would be impossible.

From the begining, I said it is a simple calculation, it depends on your Abis ressources but for us 2EDGE TS/cell aren’t enough and Confact 4 have more risk of Signaling congestion.

this calculation is for E///?? can you tell me what value can we take for ZTE system?14th June 2011 at 07:59 #66437njGuest
I don’t know for ZTE, please ask Pix,

i don’t know e/// nor zte. However, the computations we did are widely applicatble to any EGPRS system.
I would use the approach from NJ, which is simpler and will work every where.
Sheldon is using some specific e/// features I guess, which gives a more aggressive usage of abis resources.

Hey Sheldon are you using flexible Abis for your E-network are you doing this with static configutation.16th June 2011 at 14:47 #66440SHELDONGuest
We’re using a static abis configuration. We’re not using any special abis feature.16th June 2011 at 17:15 #66441MickeyGuest
Hi in below calculation, what is Confact & why we have considered only 12 TSL for EDGE21st September 2015 at 10:25 #66442ayu nareswariGuest
i have question for this, i think
my config abis already true,
i have 4/4/4 config, 2 SD each sectors, and 1 bcch, confact 2,
numreqegprs 4 each sectors,
but still alarm “INSUFFICIENT EGPRS”
then i check on rrgsp:scgr=tg;
the result is no defined scgr,
and i check on rxapp,
the dcp for 64K is “NO” for all dcp, there are no dcp with 64K “YES”,
is this the cause of alarm?
how i can config 64K to yes?
