ADSL1/ADSL2/ADSL2+, Lan x 4, USB, Mbps
The professional VPN router LANCOM 1781VA-4G provides high-speed Internet access either via LTE (up to 100 Mbps), VDSL2 (up to 100 Mbps) or ADSL2+. Due to these versatile connections it is the high-performance basis for maximum failure resiliency, e.g. for checkout connections, cloud or online services. On top of that, it is equipped with two SIM card slots (dual SIM) for intelligent cellular backup scenarios, e.g. in case of provider failure or the consumption of the cellular data limit. 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 cater for maximum performance and are also energy-efficient based on IEEE 802.3az: If no data is transmitted over an interface, the power consumption shuts down automatically. The LANCOM 1781VA-4G further supplies everything that a modern enterprise network needs, such as comprehensive Quality-of-Service capabilities and an object-oriented firewall.
