The system has detected a locked (LCK) maintenance signal on an incoming 10G optical channel data unit (ODU2) signal (from the OTU2 port). This indicates that an upstream connection is administratively locked and no signal is passed through.

Likely Cause |
An upstream network element has administratively locked the ODU2 signal from user access while performing a maintenance activity (for example, set-up tests). SA when the OTU2 is the destination of an OCH cross-connection and at least one of the client ports has a Signal Type of other than STNA. Otherwise, the alarm is reported as NSA. |
