The SONET DCC Termination Failure alarm occurs when the ONS 15454 loses its DCC. Although this
alarm is primarily SONET, it can apply to DWDM. For example, the OSCM card can raise this alarm on
its OC-3 section overhead.
The SDCC consists of three bytes, D1 through D3, in the SONET overhead. The bytes convey
information about operation, administration, maintenance, and provisioning (OAM&P). The ONS 15454
uses the DCC on the SONET section layer to communicate network management information.
On the ONS 15454 OC-192 card, the laser is on when the card is booted and the safety key is in the on
Warning
position (labeled 1). The port does not have to be in service for the laser to be on. The laser is off when
the safety key is off (labeled 0). Statement 293
