  • Overview
  • High Performance VDSL2 Data Rate over Existing Phone Lines

    PLANET VC-820M is an 8-Port VDSL2 Managed CO (Central Office) Switch with 2 Gigabit TP/SFP combo interfaces. The VDSL2 CO Switch is perfectly designed for the networking applications of communities, network service providers, SIs, IP surveillance providers, etc. It is based on two core networking technologies, Ethernet and VDSL2 (Very-high-data-rate Digital Subscriber Line 2). Worked with PLANET VC-23x series of VDSL2 CPE (Customer Premises Equipment), the VC-820M offers the absolutely fastest data transmission speeds over the existing copper telephone lines providing an ideal solution to the last-mile connectivity.

    Each VDSL2 interface of the VC-820M provides two copper phone ports, one for VDSL2 connection and the other one for POTS (Plain Old Telephone Service) connection. To share the existing phone line with POTS, the VC-820M has a built-in POTS splitter that helps the voice over telephone and network data to transmit over the same wire without being interrupted.

    Delivering Highly-demanding Connectivity for ISPs/Triple Play Devices

    As the demand for home broadband connections increases, the VDSL2 technology is the next media to support the integration of home services and provides a significant transmission speed faster than that of the current cable modem and ADSL technology. The VC-820M applies the EoVDSL (Ethernet over VDSL) to providing up to 100Mbps download capability and makes the following multi-media services more efficient on the local network:


    ■ VoD (Video on Demand)

    ■ Voice over IP

    ■ Video Conferencing/Video Phone

    ■ On-line Gaming

    ■ Internet Radio/On-line Music

    ■ Long-distance Education

    The VC-820M offers an excellent bandwidth to meet the requirements of the triple play devices for home entertainment and communications.

    QoS Features to Ensure Best Performance

    The VDSL2 Switch contains robust QoS features such as port-based, 802.1p priority and IP ToS/DSCP to ensure the best performance of its VoIP and video stream transmission, thus empowering the enterprises to take full advantage of the limited network resources.

    Selectable VDSL2 Data Rate for Service Differentiation

    Through the management interface, the administrator can control the data transmission speed of each VDSL2 interface. Telecoms and ISPs can immediately and remotely upgrade/downgrade bandwidth service upon different demands.

    Efficient Management

    To further expand the current network, PLANET VC-820M provides console and Telnet command line interfaces, and advanced Web and SNMP management interfaces. With its built-in Web-based management interface, the VDSL2 switch offers an easy-to-use, platform-independent management and configuration facility. The VDSL2 switch supports standard Simple Network Management Protocol (SNMP) and can be monitored via any standard-based management software. For text-based management, the VDSL2 switch can also be accessed via Telnet and the console port. Moreover, the VDSL2 switch offers secure, remote management by supporting Secure Socket Layer (SSL) connection, which encrypts the packet content at each session. The features above provide an efficient way to manage the devices from the internet environment with no need to add extra secure system either by means of hardware or software.

    Robust Layer 2 Features

    For efficient management, via Web interface, the VC-820M can be programmed for basic switch management functions, such as port speed configuration, port link aggregation, IEEE 802.1Q VLAN and Q-in-Q VLAN, port mirroring, Rapid Spanning Tree, and ACL security. Additionally, the firmware includes advanced features such as IGMP snooping, QoS (Quality of Service), broadcast storm and bandwidth control to enhance bandwidth utilization.

    Advanced Security

    The VDSL2 switch offers comprehensive Layer 2, Layer 3 and Layer 4 Access Control List (ACL) to filter out unwanted traffic. Its protection mechanisms comprise RADIUS and port-based 802.1X user and device authentication. Moreover, the VDSL2 switch provides MAC filter, static MAC, IP/MAC binding and Port Security for enforcing security policies to the edge. The administrators can now construct highly-secured corporate networks with considerably less time and effort than before.

  • Applications
  • MTU/MDU/Hospitality Solution

    IPTV, VoD and digital message broadcasting services are the worldwide hot trends, and more and more service providers have gradually upgraded the client-side devices from analog system to digital system. PLANET VC-820M VDSL2 CO Switch and VC-23x VDSL2 CPEs are the best solutions to quickly providing cost-effective and high-speed network services by utilizing the existing telephone wire infrastructure. IP network installation is straightforward and requires no new wiring. With enough bandwidth, the VC-820M with up to 100/100Mbps symmetric capability enables to make multi-media services on the local Internet, such as VoD (Video on Demand), Voice over IP, video phone, IPTV, distance education and so on, more efficient. This kind of infrastructure will minimize the burden on the Internet.
    Last Mile of FTTx Deployment

    The VC-820M provides an symmetric data rate of up to 100/100Mbps within 300m and in long-range connections, where the performance of the pervasive telephone line network can be ultimately enhanced. With the two built-in mini-GBIC 1000BASE-SX/LX SFP (Small Form-Factor Pluggable) interfaces, the deployed distance of the VC-820M can be extended from 550 meters (multi-mode fiber) to 10/50/70/120 kilometers (single-mode fiber). The various distances of SFP and Bidi (WDM) transceivers are optional for customers. The long-distance support feature makes the VC-820M a great and ideal solution for FTTx (Fiber to the Building, Fiber to the Campus or Fiber to the Home) applications. It supports high-bandwidth VDSL2 over the existing telephone wires in the “last mile” from the ISPs’, telecoms’ and service providers’ fiber nodes to the buildings and customers’ homes.
