(TSE: 2391), the world's leading broadband access solutions provider today announced its new IP-based Discrete Multi-Tone (DMT)-based VDSL2 solution: VES-1616F-44/VES-1624F-44 VDSL2 switch with P-872H/P-870MH VDSL2 modem. ZyXEL's newly announced VDSL2 solution combines various features that optimize broadband performance and quality of service; offers services providers with carrier grade solution for quality triple play services.

The ZyXEL VES-1616F-44/VES-1624F-44 is a 16-port/24-port, 1.5U VDSL2 Switch, providing a maximum of 100Mbps download and 50Mbps upload bandwidth.

The VES-1616F-44/VES-1624F-44 supports IEEE 802.3ad with load distribution control and fail-over recovery. To balancing traffic loading, the VES-1616F-44/VES-1624F-44 distributes traffic to each trunk port based on the source and destination MAC addresses. 

Enable IGMP snooping on the VES-1616F-44/VES-1624F-44 to improve service quality for IP multicasting applications. This prevents unnecessary forwarding of multicast traffic to all subscribers, thus optimizing bandwidth utilization for bandwidth-consuming applications such video streaming. In addition, the Multicast VLAN registration (MVR) feature allows the VES-1616F-44/VES-1624F-44 to forward the same video streams to device in specific VLANs. Through this intricate technology, duplicate video streams can be reduced significantly making the VES-1616F-44/VES-1624F-44 your first choice in an MoD environment.

The VES-1616F-44/VES-1624F-44's Rate Limiting feature Allows service providers to limit bandwidth on subscriber ports at steps of 64Kbps. This allows service providers to offer tiered service plans.
