תאור

Affordable high-speed connectivity for home and small office
Router ADSL2 + DSL-2540U/BRU/C3B - an affordable, high-performance device for home and small office. Through the use of standard ADSL2 / 2 + speeds up to 24Mbps downstream / s, media 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
The security features allow you to prevent unauthorized access by malicious users to your home and office network through the Internet. DSL-2540U/BRU/C3B 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 transfer and enabling to avoid problems with traffic congestion. QoS support allows more efficient data transfer applications that are sensitive to delays, such as VoIP, streaming multimedia and on-line games on the Internet.
