Assem,

you should ask all your questions at once 🙂
radio link failure : the radio link counter has expired. It means that during few consecutive seconds (def. 9s), there was no SACCH UL that was succesfully decoded by the BTS.
It is an indication of the TCH quality : if the SACCH could not be decoded, then the TCH probably can’t be decoded either.
