The ZyXEL VES1616FT-54/VES1624FT-54 is a DMT (Discrete Multi-Tone)-based VDSL2 solution that dynamically adapts the bit rates to conditions on the local loop to offer excellent performance even on noisy lines. Network administrators are relieved 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, as it complies with the G993.2 VDSL2 standard and QoS control is available on VDSL2 links.
The VES1616FT-54/VES1624FT-54 supports IEEE 802.3ad with load distribution control and fail over recovery capabilities that distribute traffics to each trunk port based on the source and destination MAC addresses to balance traffic loads.
Administrators can enable IGMP snooping to optimize service quality for IP multicasting applications. The VES1616FT-54/VES1624FT-54 provides this feature to prevent unnecessary forwarding of multicast traffic to all subscribers, and thus optimizes bandwidth utilization for bandwidth-consuming applications such as broadcast video. In addition, the Multicast VLAN Registration (MVR) feature checks all connected VLANs to see if they request the same video stream. Through this exclusive mechanism, the number of video streams can be reduced significantly and this provides more advantages to MoD environments, and QoS are supported on VDSL2 links.
The ZyXEL VES1616FT-54/VES1624FT-54 provides Rate Limiting features that allow service providers to offer tiered services. Rate Limiting on subscriber ports allows services to have 64 Kbps increments.
The ZyXEL VES1616FT-54/VES1624FT-54 comes with a rich set of tools to streamline your management effort. The Web-based management interface of the devices offers an easy-to-use platform, independent management features and configuration options. The VES1616FT-54/VES1624FT-54 supports SNMP and MIBs, both of which can be managed via standard-based management software. In addition to remote management capabilities, a console port is also available for local administration.
