Page 13: Chapter 1: About The Vdsl Switch-Vs2512A
Chapter 1: About the VDSL Switch-VS2512A Overview Accton’s Ethernet-over-VDSL system consists of end-user CPEs (Customer Premise Equipment) connected to a VDSL switch and splitter by standard telephone cable. The VDSL connection delivers an Ethernet data link rated up to 15 Mbps symmetric (full duplex), while simultaneously supporting standard telephone services. -
Page 14: Vdsl Technology
About the VDSL Switch-VS2512A VDSL Technology VDSL (Very High Bit-Rate Digital Subscriber Line) is at the high-end of all the DSL technologies, offering the best combination of fiber optics and copper to provide high-speed broadband Internet access. VDSL’s primary application is in providing a broadband data service to multi-tenant residential or commercial buildings. -
Page 15: Switch Architecture
Overview Switch Architecture The VDSL Switch-VS2512A employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. Management Options This switch contains a comprehensive array of LEDs for “at-a-glance”... -
Page 16: Description Of Hardware
About the VDSL Switch-VS2512A Traffic Priority This switch provides Quality of Service (QoS) by prioritizing each packet based on the required level of service, using four distinct categories with Weighted Round Robin Queuing. It uses IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based on input from the end-station application. -

Page 27: Chapter 2: Network Planning
Chapter 2: Network Planning Introduction to Switching A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. The switch has, therefore, been recognized as one of the most important building blocks for today’s networking technology. -
Page 28: Internet Connections
Network Planning Internet Connections The figure below shows a VDSL Switch-VS2512A and VDSL Splitter-VM2524 providing a broadband data service to a multi-tenant residential or commercial building. In this implementation, fiber optic cable carries data from a telephone company’s central office to the building; then the installed telephone copper wires take the data and deliver it to individual units within that building. -
Page 29: Making Vlan Connections
Sample Applications Making VLAN Connections VLANs can be based on port groups, or each data frame can be explicitly tagged to identify the VLAN group to which it belongs. When using port-based VLANs, ports can be assigned to one or more groups. Port-based VLANs are suitable for small networks. -
Page 30: Application Notes
Network Planning Application Notes For network applications that require routing between dissimilar network types, you can attach the VDSL switch directly to a router. The multimode fiber modules are fitted with SC connectors, but you can attach an ST plug to the switch using Accton’s optional SC-to-ST plug converter (Part Number: ST5002, for 62.5/125 micron cable only). -
Page 31: Chapter 3: Installing The Vdsl Switch And Splitter
Chapter 3: Installing the VDSL Switch and Splitter Preparing the Site In multi-tenant buildings, phone lines coming from the service provider are generally attached to a PBX or MDF distribution box in the basement. These lines run from the PBX to a punch-down block, and then up to the POTS terminals for individual users. The following figure displays the normal wiring before installing the VDSL switch and splitter. -
