To program the Automatic Data Dial-Out configurable options in Element
Manager, select Configuration > Resources > Dial Up Interfaces > Dial-Out
Interfaces.
WAN failover service
The WAN failover service is used in conjunction with the Integrated Router,
available only on BCM50. The Integrated Router monitors the status of the
primary WAN link. When the primary WAN link is detected to have failed, the
Integrated Router will route the traffic to the WAN Failover dial-up interface, if
one is configured. The dial-up interface can be ISDN or an analog modem.
When the WAN link recovers the dialed failover WAN connection is terminated
and the IP traffic is then routed over the primary WAN link.
The WAN Failover Interface can be programmed in Element Manager:
Configuration > Resources > Dial Up Interfaces > Global Settings
Attention: Dial-out interfaces to be used as the Failover Interface must not
be provisioned for an automatic dialout service.
Modem compatibility
The internal modem is compatible with all V.34 modems, and has been tested
with the following modems:
U.S. Robotics Sportster 33.6 FaxModem (external modem)
Microcom DeskPorte 28.8P (external modem)
