Benefits
DMT Modulation-Standard Compliance and Outstanding Performance
The ZyXEL VES1616/1624FT-54 Series 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.
Port Trunking Provides High Availability
The VES1616/1624FT-54 Series 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.

ZyXEL’s VES1616/1624FT-54 is a 16/24-port VDSL2 aggregator based on Discrete Multi-Tone
(DMT) modulation and the latest Ethernet technologies; it aggregates traffics from ZyXEL
DMT-based VDSL CPE and complies with the VDSL2 G993.2 standard.
The VES1616/1624FT-54 multiplexes data traffics into two 100/1000Base-T uplinks/
downlinks (2 SFP combo) that connect to any third-party Ethernet switch, WAN router or
VDSL Switch cascade, while the built-in POTS splitter splits and sends voice traffics to the
PSTN. The VES1616/1624FT-54 supports VDSL2 downstream speeds of up to 100 Mbps and
VDSL2 upstream speeds of up to 50 Mbps.
The VES1616/1624FT-54 provides a rich set of features and ensures interoperability with
equipments from other vendors. The features include IGMP snooping, Multicast VLAN
Registration (MVR), broadcast storm control and MAC filtering. IGMP snooping and MVR are
very useful features for VoD/MoD whereas MAC filtering enhances security and bandwidth
utilization. With a broad array of advanced, fully integrated technologies, the
VES1616/1624FT-54 enables service providers and system administrators to build cost-
effective, full-service networks that enable all kinds of media-rich applications. It also
provides QoS features within VDSL2 links.
