The NetVanta 1335 multiservice access router is a performance-enhanced platform that addresses the need of multiple networking devices in a single compact platform. In addition, the NetVanta 1335, injected with RapidRoute technology, delivers enhanced performance necessary for IP telephony, corporate connectivity and Internet access, even with advanced services enabled.The NetVanta 1335 is a modular, 1U-high, rack mountable metal chassis that offers a single-slot to house any of the NetVanta series of Network Interface Modules (NIMs) and Dial backup Interface Module (DIMs). The NetVanta 1335 also includes Gigabit SFP/1000 Base-T Ethernet interface(s) for uplink or stacking capabilities and a fully managed, non-blocking, 24-port, layer 3 switch. In addition, the NetVanta 1335 also offers an 802.3af PoE version, delivering the full 15 watts per port.Based on the ADTRAN Operating System (AOS), the NetVanta 1335 allows for the support of standards- based switching and routing functions. Switching features include 802.1Q VLANs, storm control, 802.1D and 802.1w spanning/ rapid spanning tree, link aggregation, port mirroring, GVRP, and Link Layer Discovery Protocol (LLDP) to auto-discover neighboring Ethernet devices. For IP routing it enables fast, accurate network convergence using routing protocols such as BGP, OSPF, RIP, static and default routes, and demand routing.
