The Newport Networks 1460 session border controller is a key part of the infrastructure that Service Providers need in order to sell commercially viable, managed voice and multimedia services over IP to consumer and business customers, whilst also enabling IP peering to occur.  It meets the need of Service Providers for carrier-class scalability, performance and resilience and provides network security, performs traffic management and, enables lawful intercept and emergency call handling in a VoIP environment.

The Newport Networks 1460 also allows physical separation of signalling and media providing ultimate deployment flexibility and scaling.

 

Newport Networks’ 1460 Session Border Controller 


In delivering profitable IP-based services, true carrier-grade session control becomes integral to achieving cost reduction, streamlining service delivery and customer retention. Four crucial areas define Newport Networks’ 1460 Session Border Controller as carrier-class:

  • Reliability: Unprecedented device, network and service redundancy and resilience;


  • Scalability: (Per Chassis) Up to 120,000 concurrent sessions with full Network Address and Port Translation (NAPT); up to 750 call attempts per second;


  • Security:  high volume, intelligent connection of subscribers behind NAT and firewall devices;


  • Return on investment: Reduced installation, maintenance and operating expenses; SLA compliance; new, differentiated services enabled.

 

 

At the entry level the Newport Networks’ 1460 Session Border Controller can support 5,000 concurrent calls; this can be scaled to over 120,000 concurrent calls in a single, resilient chassis.  Call processing performance can be scaled independently to achieve over 750 calls per second.
