Hi electron,
Both of these are Ericsson statistic counters:
- Any abnormal disconnect / release call on SDCCH will be counted as CNDROP, and
- Any abnormal disconnect / release call on TCH will be counted as TNDROP
Usually we used to call them number of drop (TNDROP = number of TCH Drop, CNDROP = number of SDCCH drop).
And you can find another counter for the call drop reasons, weather due to signal strength (Both link, uplink, downlink), or Quality (both link, uplink, downlink), other reason, sudden drop and Timing Advance.

I think somebody already put Ericsson KPI, counter and statistic document in this forum, just kindly search it.
How to solve means how to improve drop call. There are so many things in how to improve drop call my fiend :)
