Prerequisites for configuring modem dial backup

Last Updated : Apr 03, 2020 |

  • At least one dialer string, which determines the phone number(s) of the remote modem(s) dialed by the Dialer interface

  • A configured interface to be backed up

  • Read/write or admin access level

  • A modem: MultimodemUSB (MT5634ZBA-USB), or USRobotics USB modem (5637)

  • RAS properties:

    • A dialer string

    • Authentication parameters (username, password, PAP/CHAP)

    • IP addressing (static, dynamic, or unnumbered)

    • Routing (static, RIP, or OSPF)

    • IPSec VPN, with all necessary parameters configured

Note:

Make sure policy is configured properly at the RAS server to ensure that signaling has priority over regular traffic.
