1460 Border Controller - Product Specification

Benefits

See Also 1460 Performance tests PDF 1460 BC Data Sheet PDF

• The ability to traverse corporate, consumer and core network NAPT and Firewall devices for SIP signalling.
• Quality of Service enforcement via session admission control.
• Security protection for the core network, for customers, and for service revenue.
• Regulatory compliance providing Lawful Intercept and Emergency Call Handling.

The 1460 BC can scale between 5,000 and 190,000 signalling sessions in a single, resilient 19" chassis; call processing performance can be scaled independently to achieve up to 1,000 calls per second.

Security

Proxy pinhole firewall capabilities protect network resources and subscribers from malicious attacks; Network Address and Port Translation (NAPT) provides topology hiding and ensures connectivity to networks that use private or un-routable addressing schemes. Malicious attack prevention provided at layer 3/4 and layer 5 (SIP attacks) automatically protects the core network and thus service revenues.

Quality of Service

Session Admission Control manages traffic volumes to avoid network congestion, enabling the provision of a deterministic service level to subscribers.

Signalling Policing limits the effects of Denial of Service (DoS) attacks on the signalling plane.

DiffServ Code Point (DSCP) re-marking enables media flow differentiation based on a quality policy to be enforced on a per-user and per-session basis

Carrier Grade

The 1460 Border Controller has no single point of failure, providing in excess of 99.999% availability. It has 1+1 resilience on all system modules, including power distribution units, fans and disks, and physical link aggregation (802.3-2002) providing link resilience and load balancing. The power is distributed into six power zones with front panel indicators displaying the health of each power zone. Management is via dual, independent management networks.

The 1460 supports the secure traversal of corporate and network based firewalls and NAT devices, without deploying additional customer premise equipment or replacing existing firewalls and NAT devices. NAT bindings with User Agents are maintained by forcing the UAs to increase the frequency of their re-registrations; excess re-registration messages are filtered by the 1460 to reduce network traffic and Call Agent loading.

Regulatory

The 1460 BC used in conjunction with the 310 or 1460 Border Gateways, provides service providers with a turn-key lawful interception system designed into the signalling and media paths and delivering fully compliant Handover Interfaces.

Support for Emergency Call Handling (ECH) enables the identification of up to 20 pre-defined global and local emergency identifiers, bypassing any policing profiles.

Standards

The Newport Networks 1460 Border Controller is future proof and complies with the architectural requirements of the ETSI TISPAN standards. The 1460 BC acts as a TISPAN Interconnect Border Control Function (IBCF) device.
