Softswitching is everything:
Lower capital cost
More features
Smaller footprint
Lower operating costs
Freedom from the incumbent switch suppliers
An IP access network solution
Ready today

Reality – One Perception
CONFIDENTIAL
 Progress is being made in the industry
• Product features
• Sustained voice traffic
 Financial pressure is taking its toll
 Service providers are adopting the technology
• Slowly
• Cautiously
 First Class 5 next generation switching will be ATM based
 Next generation switching will happen

Summary
CONFIDENTIAL
Next generation switching will arrive
Plenty of work to be done in the network before
switching arrives
Maturing advanced technology will obviate the
need for “advanced slideware”
