Affordable high-speed connectivity for home and office
Router ADSL DSL-2540U/BRU/T1 - an affordable, high-performance device for home and small office. Through the use of standard ADSL2/ADSL2 + speeds downstream and 24 Mbit / s, means Quality of Service (QoS), advanced features of the firewall and integrated 4-port switch, this router allows you to organize safe and high-speed Internet connection for your home or small office .
Advanced firewall features to ensure safe operation of the Internet
DSL-2540U/BRU/T1 provides firewall security using Stateful Packet Inspection SPI, keep the minutes of hacker attacks such as Denial of Service - DoS. Before sending data to the internal SPI inspects the contents of all incoming packet headers. Access control is provided with packet filtering based on MAC / IP-address of the source and receiver.
Functional QoS to ensure good transmission quality
The router supports multiple priority queues for groups of home and office users, providing a reliable connection for data transmission and providing an opportunity to avoid problems with traffic congestion. QoS support allows more efficient transfer of applications, delay-sensitive, such as VoIP, streaming multimedia and on-line games on the Internet.
