If only dial-up connections are available, the NetGuardian can report alarms via its internal 33.6K modem.

Dial-up only

If your remote sites are distant from both LAN and serial networks, the NetGuardian can report alarms over its dial-up modem. Since dial-up connections can be expensive, the NetGuardian will only dial out when it has an alarm to report.

The NetGuardian can report directly to T/Mon NOC using dial-up connections - or, as shown in the diagram, the NetGuardian can initiate a dial-up connection to a PPP server to report SNMP traps over LAN.
