The dual LTE NB2700 supports common LTE frequencies with one module and LTE 450MHz with a seccond one. These LTE modules can be used to balance traffic and can also be assigned to individual applications.

The RS232 interface is accessible by the SDK software development kit or can be used as remote serial port using the device server.

The NB2700 has two isolated digital I/Os for connecting any kind of actors and sensors. The I/Os are accessible by SDK, command line, web services, SNMP, Modbus or SDK programms.

Memory sticks and other USB devices can be attached on the USB port for remote access or local use. Software and configuration update using USB sticks is an elegant and efficient way to roll-out devices.

The router software provides all major VPN technologies like IPSec, GRE, PPTP and OpenVPN supporting both client and server mode. Using the intuitive web GUI allows to connect two devices via VPN wiht public-key-infrastructure.

Several services like DHCP, DHCP releay, DNS proxy, DynDNS agent, telnet/ssh server, web server, e-mail and SMS client are implemented in the router software.
