Description
Choose Auto or Manual Mode. If you are using manual
mode, you will need to access the Configuration Utility
to establish an Internet connection through the mobile
connection. Click Connect to establish a connection
when required. Click Disconnect to tear down the
connection.
NOTE The Ethernet Connection Recovery and Interface
Connection Failover works only if the Connection Mode is set
to Auto. If you select Auto, you must also select Connect on
Demand and Keep Alive.
Select this option to enable the SRP to terminate the
Internet connection after it is inactive for a specified
period of time (Max Idle Time). If your Internet
connection is terminated due to inactivity, this option
allows the modem to automatically re-establish a
terminated connection when a user attempts to access
the Internet again.
In the Max Idle Time field, enter the number of minutes of
idle time that can elapse before your Internet connection
terminates. The default Max Idle Time is 5 minutes.
The Tunnel Protocol (PPTP/L2TP) is supported through
a USB modem by one of these methods.
• NONE. Select this option to disable protocol
tunneling.
• PPTP/L2TP. Select PPTP or L2TP depending on
the service that you want to use. You must also
provide the server IP address, user name, and
password.
• Follow Ethernet WAN configure. Select this
option to make the Tunnel Protocol follow the
configuration of the Ethernet WAN.
