Description: A change in the DCD (Data Carrier Detect) signal indicates that the modem connection status has changed. For example, if the DCD signal changes to low, it indicates that the connection line is down. When the DCD signal changes to low, the NPort 6000 series device server will immediately send an SNMP trap.

What is trapDCDchange?

When enabled, the NPort sends an SNMP trap whenever the serial DCD signal changes state, e.g. going low to indicate the attached modem's connection dropped; the trap-based counterpart to mailDCDchange.
