Perfectly Designed for FTTx Last Mile Applications
The PLANET VDL-2420MR series is a telecom-level high performance VDSL2 IP DSLAM (Digital Subscriber Line Access Multiplexer) with 24-Port VDSL2, 2-Port Gigabit TP / SFP combo interfaces, Hot-Swappable AC/DC Redundant Power System and robust Layer 2+ switching features. The VDL-2420MR series is fully compliant with the ITU-T G.993.2 standard and supports VDSL2 30a profiles to offer maximum download and upload line rate up to 100/100Mbps on the existing twisted pair lines. The VDL-2420MR helps service providers to easily provide high bandwidth demanded triple-play services such as IPTV, HDTV, Video Phone and Internet Gaming at the same copper line and uplink to the core / metro Ethernet network through the two Gigabit fiber optical interfaces. It is an ideal CO solution for FTTx Last Mile applications of broadband access by ISPs, Telecoms and campuses.
Comprehensive and Advanced VDSL2 Configuration
For the bandwidth and distance of broadband access, the VDL-2420MR VDSL2 IP DSLAM supports multiple selective VDSL2 profiles (8a, 8b, 8c, 8d, 12a, 12b, 17a and 30a) and 997/998 Band plan to each subscriber line. To help the ISPs provide always on internet access service in different physical line installation environments, the VDL-2420MR supports configurable DPBO (Downstream Power Back-Off) and UPBO (Upstream Power Back-Off) to adjust the downstream / upstream transmit power levels for service provider to reduce the interference by nearby wires. Furthermore, it can be configured on a per-link basis for transmission mode, rate limitation and SNR (signal-to-noise) margin. These advanced VDSL2 functionalities help service providers to adjust the line performance to ensure the VDSL2 service not be impacted by other xDSL services in the same binder group and building a stable and reliable IP DSLAM solution.
High Speed Connectivity for ISP / Triple Play Devices
As the demand of 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 VDL-2420MR series 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 VDL-2420MR series gives the excellent bandwidth to satisfy the triple play devices for home entertainment and communication.
Traffic Flow QoS Ensuring for Application Services
The VDSL2 DSLAM 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.
Efficient Management
Afford the current network to grow and expand, the PLANET VDL-2420MR series 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 DSLAM offers an easy-to-use, platform-independent management and configuration facility. The VDSL2 DSLAM supports standard Simple Network Management Protocol (SNMP) and can be monitored via any standard-based management software. For text-based management, the VDSL2 DSLAM can also be accessed via Telnet and the console port. Moreover, the VDL-2420MR series 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 for the administrators 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 VDL-2420MR series 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 VDL-2420MR series 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 DSLAM 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.
Extremely Reliable Design to Ensure Continuous Operation
Power Redundant
The VDL-2420MR series supports the optional hot-swappable Redundant Power System (RPS) to ensure continuous operation. The VDL-2420MR equips with one 100~240V AC power supply unit and the VDL-2420MR48 equips with one DC -48V power supply unit on their standard package. To enhance the reliability, both the VDL-2420MR and VDL-2420MR48 provide one spare power supply unit slot for optional 100~240V AC or DC -48V redundant power supply installation. The continuous power systems are specifically designed to handle high tech facilities requiring the highest power integrity available. Also, the -48V DC power supply implemented makes the VDL-2420MR series VDSL2 DSLAM as a telecom level device that can be located at the electronic room.
Temperature and FAN Status Monitoring
The VDL-2420MR series is equipped with temperature sensor and cooling fans to ensure reliable operation. Whenever there is abnormal temperature detected or cooling fan service stops, the managed VDSL2 DSLAM would display related information on the Web management interface. Therefore, it helps the administrator to efficiently manage the managed VDSL2 DSLAM operation
