DMT modulation - standard compliance and outstanding performance
The ZyXELVES-1608FA-34/VES-1608FA-35/VES-1616FB-35, a Discrete Multi-Tone (DMT)-based VDSL2 solution, which dynamically adapts the bit rate to conditions on the local loop, offers excellent performance even over noisy lines. Network administrators become free from manually testing lines and constantly adjusting equipment to noise conditions. Both IEEE’s 802.3ah Ethernet in the First Mile (EFM) Task Force and T1E1.4 Working Group selected DMT as its worldwide VDSL line-coding standard.
Port trunking provides high availability
The VES-1608FA-34/VES-1608FA-35/VES-1616FB-35 supports IEEE 802.3ad with load distribution control and fail over recovery, which distributes traffic to each trunk port based on the source and destination MAC addresses, balancing the traffic load. There are four Giga port (2 SFP combo) enlarge downlink/uplink capability.
Traffic prioritization provides quality services
Administrator can enable IGMP snooping to optimize service quality for IP multicasting applications.
The VES-1608FA-34/VES-1608FA-35/VES-1616FB-35 prevents unnecessary forwarding of multicast traffic to all subscribers, thus optimizing bandwidth utilization for bandwidth-consuming applications such as broadcast video. In addition, the Multicast VLAN registration (MVR) feature checks all the VLANs to see if they request the same video stream. Through this exclusive mechanism, the video streams can be reduced significantly and thus be very advantageous in MoD environment.
