• Increase of Call Processing Performance by factor 5

• Enough Performance for more than 1 million subscriber MSC => enough

capacity until 2010

• Evolution of proven CP concept: same superior quality and well known

3. Benefits of PowerCP3. Benefits of PowerCP


• Seamless integration into existing platform due to compatible interfaces -

only partial HW replacement necessary

• One APS supports PowerCP (CP113E) and CP113C without further

modifications

• Solutions of other providers are based on complete new HW: this requires

severe SW modifications and a new stabilization phase.
