• The VES-2500 is QAM-based 2-band VDSL switch, a scalable platform for delivering VDSL service. Flexible configuration of the VES-2500 allows for maximum scalability to meet a range of requirements. It is well suited for a variety of installation scenarios including campuses, central offices, and multi-tenant unit (MTU) applications.
  
• The VES-2500 has a 6-slot chassis, which enables administrators to add resources, as they are needed. Service providers can start with one VLC1124A VDSL line card, and add more VDSL line cards to increase deployment as the number of subscribers increase. Such flexibility minimizes the initial investment.
  
• With the help of external Ethernet switches, the VES-2500 can be filled simultaneously with six VDSL line cards to support up to 144 subscribers. The external switches not only allow more users on one chassis, but also help increase convenience when network topology or network interfaces change. ZyXEL presents a full range of Dimension switches with different port densities and various WAN connection interfaces.
  
• The IEEE 802 standard-based firmware in VLC1124A VDSL line card provides a rich set of features and ensures interoperability with equipments from other vendors. The firmware includes advanced features such as bandwidth management, 802.1X, IGMP snooping, and MAC address filtering to enhance service differentiation, network security and bandwidth utilization.
  
• The advanced design of the VLC1124A enables service providers to quickly supply broadband service to a high number of customers at lower costs than previously possible.
  

• 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.

• VDSL, the fastest offering of DSL, provides a much higher bandwidth than other DSL technologies. Ethernet over VDSL extends Ethernet over single-pair copper wiring at distances of up to 1.5km. This technology provides a cost-effective, readily available, and rapidly deployable solution that offers needed bandwidth to multi-tenant units (MTUs).
  
• VDSL has changed the fundamental economics of broadband services for the MTU marketplace. Tenants don't have to suffer the limited bandwidth. Even small to medium-sized corporations can receive the same services as large companies. With VDSL, MTUs gain a cost-effective broadband solution that preserves their existing infrastructure, and in the process, building owners or service providers receive a compelling new source for revenue generation.
  
• ZyXEL's VDSL solution is comprised of a VDSL Ethernet switch , VES-1012 and a CPE modem, Prestige 841. The VES-1012 multiplexes traffic from 12 VDSL subscribers into one or two 100M Ethernet ports that connect to any Ethernet switch or broadband router. With the VES-1012, Ethernet over VDSL can run up to 1.5km at the speed of 5Mbps, which proves to be a promising technology and revenue generation tool for building owners and service providers.
