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

Newbridge Multiservice Platform: Carrier-Class Availability and Reliability
• Fully redundant control, fabric, power, cooling synchronization and interfaces
• Five to Six 9’s Availability in fully redundant 1:1 configurations• Hitless Line Card S/W upgrades - datapath resiliency• Hitless system upgrades with redundant configurations• Interface Automatic Protection Switching (APS), 50 msec• Path restoration using S-PVCs, S-PVPs and 46020 re-route• Architectural simplification - fewer common control
components• Startup, Background and Directed diagnostics
Good enough for public switched voice
