Key points:

  • 4G LTE with automatic fallback to 3G
  • Remote out-of-band management
  • 3-year warranty
  • Part of a best-in-class business continuity strategy


The AirLink® ES440 enterprise gateway delivers mission-critical 4G LTE connectivity when primary landline connections are unavailable. Deployed with an enterprise router, the ES440 supports a best-in-class business continuity strategy by enabling remote out-of-band management (OOBM) capability to network operations while leveraging the router’s instant failover and firewall features.

Using the AirLink ES440’s serial port to connect to the console port of the router, IT administrators can troubleshoot and repair network equipment over wireless wide area networks (WWAN). This terminal server capability allows operation centers to remotely reboot, configure, and update a router via the ES440 using Reverse Telnet and SSH protocols. As a result, remote personnel no longer need to manually reset their networking equipment and IT administrators can dramatically reduce the number of field visits.
