netwrok expansion is taking

place not in accordance with real

traffic. And since we are already

have call blocking as KPI, why

we need this KPI Used Erlang/ Created Erlang

>=90%

Why this should be a KPI. We

are measuring anyway the swith

performance as part of the KPI

(SCR). Any high loading of the

Switch will reflect in those KPIs
