The NetGuardian can report over 202, FSK, or RS-232 directly to T/Mon NOC, or over RS-232 or dial-up to a PPP server.

Serial transport with dial-up backup

The NetGuardian supports LAN and dial-up transport as standard, but you can also order your NetGuardian with an optional 202 modem, FSK modem, or RS-232 interface.

With these interfaces you can support dedicated circuits over copper or fiber and analog channels over analog or digital radio.

With serial transport, you will most likely report alarms over DCPx protocol to the T/Mon NOC Remote Alarm Monitoring System - but the NetGuardian can send SNMP traps via PPP over RS-232.

Even if you're using a serial connection as your primary alarm reporting channel, the NetGuardian's dial-up modem can be a useful backup data path. If anything goes wrong with the serial connection, you can still receive alarms via dial-up reporting.
