Implementing international standard-based ITU-T/ETSI G.SHDSL transmission (G.991.2) with robust IP routing, concurrent bridging functions and built-in 4-port Ethernet switch, NBG400 Series Business Gateways are perfect for mission-critical applications such as campus networking, multimedia services and network gateway access.
Interoperating with NexComm's Ethernet-based SHDSL Mini-DSLAM NS4024G, the NBG400 Series provide a cost-effective altemative of Ethernet networking of Point to Multi-Point application for SMBs that have multiple buildings in a campus-like environment. By leveraging Tag-based VLAN an STP capabilities of the NBG400 Series, the campus ensures a highly secure and reliable network. By utilizing the Ethernet-based QoS capabilities the campus can take advantage of voice and video applications. This application requires no new infrastructure, and results in a low-cost, plug-and-play solution with low management overhead.
