The downstream equipment has detected a receive signal failure, and has
inserted MS-RDI as a consequent action.
Locally no actions can be taken. Analyze the alarm state of the downstream
equipment and take appropriate measures.
The downstream equipment has detected one of the following failure conditions
at its receive side:
•
STM-4 MS AIS (Multiplex Section Alarm Indication Signal)
•
STM-4 LOS (Loss Of Signal) or
