Adtran 4700341F2#25 NETVANTA 3140 25 SESSION SBC

Description

The NetVanta 3140 is a high-performance fixed-port Ethernet router that supports converged access and high-quality voice services. Provides three routed, auto-sensing Gigabit Ethernet interfaces. This product is ideal for carrier-bundled offerings and enterprise-class Internet access for high-speed, secure corporate connectivity. The NetVanta 3140 is available as a desktop or rackmount platform. Flexibility and Redundancy The NetVanta 3140 is ideal for multiple applications where Ethernet redundancy is needed given the three Gigabit ports that can be LAN or WAN oriented. This can be achieved with two Ethernet-delivered access services that provide immediate failover to the active link whenever a downlink event occurs. Additionally, the NetVanta 3140 features a USB interface that can be used for 3G/4G backup. Many deployments still have separate voice and data networks, and the NetVanta 3140 is perfect for these too with a single WAN link, the other two Gigabit interfaces can achieve this. Standards Protocols The NetVanta 3140's versatile hardware platform is complemented by AOS. The AOS enables support for static and default routes, demand-based and policy-based routing, and enables fast and accurate network convergence using routing protocols such as BGP, OSPF, RIP, and PIM sparse mode for multicast routing. Multihoming is also available to provide redundant or backup WAN links to multiple ISPs, ensuring a widearea connection. Hierarchical QoS QoS also supports delay-sensitive traffic such as VoIP or video. To prioritize mission-critical traffic and control network congestion, NetVanta 3140 uses Low Latency Queuing, Weighted Fair Queuing (WFQ), Class-Based WFQ, and DiffServmarking to establish the priority of IP packets routed over the WAN. VoIP Ready In combination with QoS features, a specialized SIP ALG allows SIP traffic to traverse NAT-enabled firewalls. For enterprise networks, this
