Dell SonicWALL network security appliances with a USB extension port can support either an external 3G/4G interface or analog modem interface. When the appliance does not detect an external interface, a 3G/4G/Modem entry is displayed in the left-side navigation bar.
The 3G/4G/Modem > Status page displays the active/inactive status of the connection as well as the signal strength.
By default, the Dell SonicWALL network security appliance will attempt to auto-detect whether a connected external device is a 3G/4G interface or an analog modem interface. You can manually specify which type of interface you want to configure on the 3G/4G/Modem > Settings page.
The 3G/4G/Modem Device Type drop-down menu provides these options:
|
•
|
Auto-detect - The appliance attempts to determine if the device is a 3G/4G or analog modem.
|
|
•
|
3G/4G/Mobile - Manually configures a 3G/4G/Mobile interface.
|
|
•
|
Analog Modem - Manually configures an analog modem interface.
