Суич Planet VC-820M, 20 порта, 2x 10/100/1000 Mbps RJ45, 2x 10/100/1000 Mbps SFP, 8x VDSL2 RJ11, 8x POTS RJ11

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:
■ IPTV/HDTV
■ 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.
