Reply To: High SDCCH Assignment Failure


well, that’s your philosophy… but actually what is the point of CSSR ?
One number to show maximum amount of info about your network.
If your CSSR takes only one indicator (tch assign succ %) then it’s quite limited.
If your CSSR takes more indicators together, then – ok – it might not show “only” the CALL s.s.r, but it gives a good idea on how well-tuned is your network.

CSSR + CDR = wide overview of QoS
those are really just “management” KPI, they are absolutely useless for troubleshooting 🙂
