Dial Backup

Use the Dial Backup option to configure a backup connection to the Internet through an internal V.90 (model
5835 only) or an external asynchronous modem connected to the console port. This backup connection can be
activated in the event of WAN service interruption. During an interruption to the WAN interface connection, the
router will use the dial backup modem connection while waiting for WAN service to be restored. Once the WAN
link is active again, Dial Backup will automatically switch back to the WAN service.
To configure a dial backup connection:
1. Click Dial Backup on the left navigation pane of the Router Information page. This displays the Dial Backup
page.
2. Click Enable Dial Backup.
3. Enter the User name and Password to use for the dial up connection. This information is provided by your
ISP.
4. In Phone number, enter the ISP's dial up phone number.
5. Optionally, in Alternate Phone number, enter an alternate phone number to use in the event the first
number is unavailable.
6. Next to Using, select one of the following to specify the type of modem to use for the dial-up connection:
•
Internal Modem: Use an internal modem for the dial-up connection. (If the internal modem has not been
key-enabled, the modem type will automatically be set to External Modem and cannot be changed.)
•
External Modem: Use an external modem for the dial-up connection. Even if an external modem is not
physically connected, External Modem can still be selected.
7. Click Apply. This displays the Dial Backup Configuration page for the type of modem selected:
•
Internal Modem
•
External Modem
