Newbridge Multiservice Platform: Call Processing

• 3000 sustained calls per second (call set-up and tear-down)

• superior re-route and disaster recovery capabilities

• Parallel Call processing capabilities• load proportional processing across all ports• optimized for ‘hot spot’ rerouting of failed trunks• SVC hot redundancy• Availability

– SVC S/W upgrades do not affect existing Calls

Processes more calls per second than a typical voice switch
