Guess u dont understand what i asked for and seems u dont know at all!!
I asked for the reason for high TCH A IF fail which has nothing to do with bcch-tch covergage footprint, alrms, interference, congestion.
It is totaly related to A-Interface/MSC interface..pls respond only if u can help

be clear about the ques u r asking.!

no body can guess from this TCH A IF that its is related to a interface. try to put things which are generic in gsm and not according to ur specific terms.
