Overview:

Ultimate Internet Connection For Your Homes
The ADSL2+ Modem (DSL-520B) is an affordable high-performance modem ideal for your home or small office. This modem supports high download speeds, Quality of Service (QoS), and extensive firewall protection, providing all the essentials that a home or small office would need to establish a secure and high speed remote link to the outside world.

Extensive Firewall Features for Added Internet Defense
Security features prevent unauthorized access of Internet intruders from entering your home network. This modem provides firewall security using Stateful Packet Inspection (SPI) and Denial of Service (DoS) attack protection. SPI inspects the contents of all incoming packet headers before deciding what packets are allowed to pass through.

Quality of Service for Smooth Traffic
Quality of Service (QoS) supports multiple priority queues to enable a group of home users to experience the benefits of smooth network connection of inbound and outbound data without concern for traffic congestion. This modem's QoS support allows users to enjoy high ADSL transmission for applications such as VoIP, streaming multimedia and online games.

High-Speed Internet Access
Always on high-speed internet connection, this modem allows you to do all of your favorite things on the Internet. Watch TV, listen to live music, play games, and experience clear Internet phone calls. Now, smooth streaming multimedia and VoIP voice are possible at home and in the office through a simple connection with this modem.

* ADSL speeds may vary depending on your individual contract with or services offered by your Internet Service Provider (ISP) and the distance of the modem from the ISP's DSLAM.
