The device supports a 3G/4G cellular WAN interface using a USB-based 3G/4G cellular
modem. This cellular WAN interface can be used as the primary WAN interface or as an
optional WAN backup when the primary WAN (e.g., WAN Ethernet) fails. The WAN
connection type is a point-to-point protocol (PPP) over cellular.
Note: To check if your third-party cellular modem is supported by the device, please
provide the modem's model details to your AudioCodes sales representative.
