For The SD Drop Reasons in Nokia system you can check Report No 166 and 204. You will find out the sd drop reasons.

“working SDCCH channel below threshold”.

What I think your cell is required more SDs.

Could you tell me your sd configuration against Cell Trx Configuration.

My SDCCH Configuration is one SDCCH block per TRX, still having high SDC drop!!!

how to reduce the sd drop an we have more sd allocate after that i face problem

[Iqbal Ahmed]

Dear Swadhin ,

1.you need to check the 236 report for Overshooting.

2.need to check the timer for sdcch. if its less increase it.

3.with 196 report check the quality of the particular trx on which sdcch is present .if quality seems to be bad then change the sdcch to another trx.
