2.7.56 EOC
Default Severity: Minor(MN), Non-Service-Affecting (NSA)
SONET Logical Object: OCN
The SONET DCC Termination Failure alarm occurs when the ONS15310-CL or ONS 15310-MA loses
its DCC. The section data communication channel (SDCC) overhead consists of three bytes, D1 through
D3, in the SONET overhead. The bytes convey information about Operation, Administration,
Maintenance, and Provisioning (OAM&P). The node uses the DCC on the SONET section layer to
communicate network management information.
