Overview
High Performance VDSL2 Data Rate over Existing Phone Lines
PLANET VC-820M is an
8-Port VDSL2 Managed CO Switch (Central
Office) with 2-Port Gigabit TP / SFP combo interfaces. The
VDSL2 CO Switch is perfectly designed for the networking applications of
Community, Network service provider, SI (System Integration), IP
Surveillance provider and etc. It is based on two core networking
technology, Ethernet and VDSL2 (Very-high-data-rate Digital Subscriber Line
2). By co-working with PLANET developed VDSL2 CPE (Customer Premises
Equipment) the VC-23x series CPE, it offers the absolutely fastest data
transmission speeds over existing copper telephone lines which provides the
ideal solution in the last mile.
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
built-in POTS splitter that helps the voice over telephone and network data
to transmit at the same wire without being interrupted.
Delivers High-Demand Services Connectivity for ISP
/ Triple Play Devices
As the demand of home broadband connections increases for home-communication
and entertainment needs, VDSL2 technology is the next step media to support
the integration of home services and provide significant faster transmission
speed than current cable modems and ADSL technology. The VC-820M applies the
EoVDSL (Ethernet over VDSL) to provide up to 100Mbps download capability and
brings many Multi-Media services come true on local network:
IPTV / HDTV
VOD (Video on Demand)
Voice over IP
Video Conference / Video Phone
On-Line Game
Internet Radio / On-Line Music
Long distance education
The VC-820M gives the excellent bandwidth to satisfy the triple play devices
for home entertainment and communication.
Traffic Flow QoS Ensuring for Application Services
The VDSL2 Switch contains robust QoS features such as Port-Based, 802.1p
priority and also IP TOS/DSCP. It guarantees the best performance at VoIP
and Video stream transmission and empowers the enterprises to take full
advantages of the limited network resources.
Selectable VDSL2 Data Rate for Service
Differentiation
Through the management interface, the administrator can control the data
transmit speed of each VDSL2 interface. Telecom and ISP can immediately and
remotely upgrade/downgrade bandwidth service by different demands.
Efficient Management
Afford the current network to grow and expand, the PLANET VC-820M provides
console and telnet command line interface, advanced WEB
and SNMP management interface to fill this kind of demand. 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 comprises of 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.
Example 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
gradually. The PLANET VC-820M VDSL2 CO
Switch and VC-23x VDSL2 CPEs are the best
solution to quickly provide 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 up to 100/100Mbps symmetric
capability of VC-820M enables many
Multi-Media services on local Internet to
come true, such as VOD (Video on Demand),
Voice over IP, Video phone, IPTV, distance
education, and so on. The VC-820M provides
excellent bandwidth to satisfy the triple
play devices for entertainment and
communication. Meanwhile, this kind of
infrastructure will minimize the burden on
the Internet.
Last Mile of FTTx Deployment
The VC-820M provides up to 100/100Mbps symmetric data rate within 300m
and in long range connections, it provides ultra-high performance to the
pervasive telephone line network. With the two build-in mini-GBIC
1000Base-SX/LX SFP (Small Form- Factor Pluggable) interfaces, the
deployed distance of VC-820M can be extended from 550 meters (Multi-mode
fiber) up to above 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 be 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 existing telephone wires in the last mile from the ISP /
Telecom / Service providers fiber node to the buildings and customers
home.
