DSL-2540U/BRU/C2EOL EOS
Description
ULTIMATE INTERNET CONNECTION FOR HOME & OFFICE
The DSL-2540U ADSL Modem Router is an affordable high-performance router ideal for the home and small office. With its integrated ADSL2/2+ supporting high download speeds of 24Mbps, Quality of Service (QoS), extensive firewall protection and 4-port built-in switch, this router provides 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 or small office network. This router 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. Router access control is provided with packet filtering based on port and source/destination MAC/IP addresses.
QUALITY OF SERVICE FOR SMOOTH TRAFFIC
Quality of Service (QoS) supports multiple priority queues to enable a group of home or office users to experience the benefit of smooth network connection of inbound and outbound data without concern for traffic congestion. This router’s QoS support allows users to enjoy high ADSL transmission for applications such as VoIP, streaming multimedia and online games.
