Configuring USB Modems for Dial Backup

You can configure your device to “fail over” to a USB modem connection when the primary Internet connection experiences interruption.

Note: Low-latency traffic such as VoIP traffic is not supported over USB modem connections.

Note: We recommend using a Multi-Tech MultiModem MT5634ZBA-USB-V92 USB modem.

You use either the J-Web configuration editor or CLI configuration editor to configure the USB modem for dial backup.
