Abrupt nature of SDCCH blocking in n/w

Hi Pridey
I will rather suggest not to put any TCHD on any TRX if your Peak Utilisation is < 90%.In case you have to,only configure that much TCHD as is required(maybe 20% more). But then again,try tuning NBL also,because it might lead to TCH Blocking on 900 TRX's. Other than MAXRET,you have HYS,T3212,BMA,Dynamic SDCCH,etc etc to take care of SDCCH Blocking Br\\ Bijoy
