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.

This chapter contains the following topics. For more information about modem initialization, administration, verification, and remote connection, see the J-series Services Router Administration Guide.
