Figure6-21 Schematic Diagram of PM Overhead Configuration
The line side of the NE at the two ends is OTU2 service (configured according to the service type of the client
side). After being demultiplexed to ODU2, enable the monitoring function of PM overhead on ODU2 layer at the
two ends. Here the status of ODU2 layer is “unterminated”, the value of expected TTI can be set. For detailed
configuration, please see detailed steps described in 6.1.3. If the values of expected TTI and receiving TTI of the
two ends are the same, then the line configuration is correct and the signal source is correct.
The client side of NE at both ends is XGE_GFPF service (Specific service needs to be configured according to
actual demand). Enable the monitoring function of PM overhead of client side port at both ends on ODU2 layer.
Here the status of ODU2 layer is “client end signal terminated”. Set the values of sending TTI and expected TTI.
For detailed configuration, please see the detailed steps described in 6.1.3. If the values of the sending TTI and
receiving TTI of the two ends conform to the overhead establishment rules in Table 6-1, then the line
configuration is correct and the service can be normally sent and received.
After the configuration is completed, when fault occurs to the service of the monitoring segment
corresponding to SM and PM, the NMS system will report the alarm and performance instructions
corresponding to SM and PM, such as TIM, BDI, AIS and SD etc. The fault can be quickly and accurately located
according to these alarms and performances.
