Hi,
Dude we have inverse right after upgrade Drop increased from 0.85 to 1%.
That was due to AMR problem in BTS312. please describe more in your case?
Which BSC version? BSS software release? BTS software release and BTS type?

If the improvement is CSSR performance so you can check from Failed Assignments on A Interface Failed Assignments on A Interface will decrease.

I think that is depends on IP clock server.

how about Ater interface, this make me confused if A interface over IP implement, cause Ater making transcode to 64k to 16k.
is this so transparantly.
