3. Improvement/Degradation Percentage
Summary – SELONG
GFR has been successfully implemented on 22th April 2014
TCH Availability degraded was caused by Alarm Permanent Fault on cells MT33539 BMTG2
HO Success Rate degraded was caused by Transmittion issue on cells B636_MONTONGGDG
TCH Traffic <Erlangs> showing increase trend since 28 April 14
