It seems this problem is common in ericsson networks.
In out anlysis we split it into 2 parts.
1) CCALLS-CMSESTAB showing total # of failure to establish an SDCCH.
We found cells with huge values were at the location border.
This affected the overal BSC CSSR.
This affected cell CSSR & we were able to fish out cells with co BCCH.
The problem is we could not find the counter CESTIMMAS and CESTCHACTIV.
I serched in objects SDCCH & SDCCHO but to no avail. Can someoone help me on how to find it & what command to use in OSS to get the T 3101 timer?
