CAUSE: DSP Failed Other hardware problem RRC lodebalance strategy Radio interface failure has Timer for RL restore is to short Have Sent RRC Connection been attributed to some Setup, hardware failures(in sympathy SOLUTION: change hardware But do not received RRC with traffic as what happened Connection Setup Complete or to check if it is the problem at site selbone Park (BPC), Radio Link Restore 1. change the site CMP Nguboyenja (RRU)) 2. change resource shelf priority if it worked, need upgrade or repalce
