LAN-Based Monitoring with Dial-Up Backup Data Path

Maintain Site Visibility When Primary LAN Access Fails

Having a backup data path is essential for effective network monitoring. In this application a remote telemetry unit has a primary link to its master via LAN. But if the LAN connection fails, there is also a secondary path via dial-up modem to a PPP server, so alarm messages will still be sent to the SNMP manager. Alternatively, this application can be used to monitor sites that do not yet have LAN access. Because dial-up connections can be costly, the PPP connection can be configured to only initiate a connection when an alarm occurs.
