=)
well in this case, i mean call stablish failure rate.
cheking the kpi’s and counters related, all the failures causes are grouped in one single counter, wich for my vendor is (Number of communications in signaling phase released: SCCP disconnection).
they told me, this sccp’s disconnections indication are sent by the msc to the bsc.
no rf interference, or bts trk hw issues are found on this site..
any clue?
