Specifications

Product Description

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. External Switches Enhance Flexibility The VES-2500 uses external Ethernet switches to aggregate traffic from different VDSL line cards. Each VLC1124A has one Fast Ethernet interface for connecting to Ethernet switches. ZyXEL offers a full range of Dimension Ethernet switches with different port density and various WAN connection interfaces. This gives service providers a great amount of convenience and flexibility when network topology or network interfaces change. VLAN Offers Both Security and QoS(Quality of Service) The VLAN feature in the VES-2500 offers the benefits of both security and performance. VLAN is used to separate traffic from different users and to provide better security. Different services can be tagged and mapped into different priority queues. Thus, Quality of Service can be achieved and improved. Multicasting Optimizes Bandwidth Utilization Multicasting design forwards traffic only to the subscribers who request the multicast traffic. This restricts unnecessary broadcast traffic to all subscribers and optimizes bandwidth utilization for bandwidth-consuming applications such as video on demand. New mechanisms, such as 802.1p, have also emerged to ensure the quality of service. Rate Limiting Allows Service Differentiation In order to fulfill the needs of different customers, service providers need a network infrastructure that combines guaranteed performance and flexibility in service provisioning. Rate limiting on both Ethernet and VDSL ports allow service providers to offer tiered service. Remote Management Minimizes the Operation Cost In hotel applications where a Vantage SG 1000 or Vantage SG 1200 subscriber gateway is installed, remotely managing the VDSL line cards in the VES-2500 becomes a simple and easy task. The LAN device management feature in the Vantage SG 1000 and Vantage SG 1200 enables service providers to access the Dimension switches and VDSL line cards in the VES-2500 through a single IP address. Such flexibility allows for network expansion without increasing management efforts.
