VPN Router w/ Integrated VDSL & ADSL2+ Modem, EU, over POTS
The LANCOM 1781VA is a professional, high-performance VPN router for high-speed Internet access with integrated VDSL2 and ADSL2+ modem. Thus it provides maximum flexibility for a transition from ADSL to high-speed VDSL Internet connections. Likewise, an operation without splitter is possible based on ADSL2+ Annex B / J (over ISDN) or A / M (over POTS). In all industries and branches of trade with high demands on security and performance it is the ideal foundation for a professional site connectivity. With its extensive VPN capabilities, the device provides secure, high-performance connectivity to branch offices and remote workers. The four ports of the integrated Gigabit Ethernet switch ensure maximum performance and are also energy-efficient based on IEEE 802.3az: If no data is transmitted over an interface, its power consumption shuts down automatically. The LANCOM 1781VA supplies everything required of a modern enterprise network, such as comprehensive Quality-of-Service capabilities and an object-oriented firewall.
