Vision VES-1124
Recently, Ethernet has been more widely used for access applications, transport, and backbone infrastructure.
More service providers are adopting Ethernet as the first mile (EFM) in their FTTB/C deployments. Among different EFM
technologies, EFM over copper is filling the bandwidth gap between high-speed, Metro fiber networks and low-
bandwidth, copper-based services. It utilizes existing copper wires, thus giving service providers a cost-effective solution
today, tomorrow, and beyond. Furthermore, EFM uses mature Ethernet technology that allows seamless connectivity
between enterprise Ethernet LANs and the WAN.
As influential as EFM, Ethernet over VDSL has changed the fundamental economics of broadband services for the last mile
and the MTU market. With Ethernet over VDSL, small to medium sized corporations can receive the same high
bandwidth services as large companies. Additional benefits include the ability to enjoy the video, data, and voice
services, which VDSL allows, eliminating the limitations of low bandwidth. VDSL delivers cost-effective, high-bandwidth
broadband access to enterprise campus and multi-tenant buildings (commercial buildings, residential buildings, hotels,
and etc.) without new wiring.
ZyXEL’s VES-1124 is a 24-port VDSL switch based on Quadrature Amplitude Modulation (QAM) and the latest Ethernet
technologies. The VES-1124 aggregates traffic from ZyXEL’s Prestige 841-25 QAM-based VDSL CPE, and multiplexes data
traffic into two 10/100Base-Tx uplinks that connect to any third-party Ethernet switch or WAN router. The built-in
POTS/ISDN splitter splits and sends the voice traffic to the PSTN. The VES-1124 supports up to 15Mbps for both
downstream and upstream, extending Ethernet service up to distances of 1.5km.
The IEEE 802 standard-based firmware provides a rich set of features and ensures interoperability with equipment from
other vendors. In addition, the firmware includes many advanced features such as bandwidth management, 802.1X,
IGMP snooping, broadcast storm control, and MAC address filtering, which enhance service differentiation, network
security and bandwidth utilization.
With a broad array of fully integrated, advanced technologies, the VES-1124 together with the Prestige 841-25 enable
service providers and system administrators to affordably build up full service networks and to make all kinds of media-
rich applications possible.
