TRUE

FALSE

4. The following description about the composition of the SOM system, which is wrong?

The intelligent management software SOM is integrated on the U2000.

The SOM system is composed of a hardware part and a software part.

Deleting a path from the network layer only deletes the WDM path at the network layer on the NMS side

The service will not be interrupted after deleting the path from the network layer

Deleting a path from the network element layer will delete the path on the network element side and the network layer together

After deleting the path from the network layer and the network element layer, the service will be interrupted

Improper DCM configuration will lead to degradation of system signal-to-noise ratio.

For 10G systems with line fiber length within 400km,

652 DCI can be used to compensate

655LEA

DCM module is more likely to cause nonlinearity than line transmission fiber, so it is necessary to strictly control the optical power of the fiber.

Improper DCM configuration will cause degradation of receiver performance.

9. Which of the following description of the client path created by the path method is wrong?

Select the "Activate" check box. After the trail is successfully created, it will be delivered to the network element layer. Otherwise, the path configuration teaching data will only be saved on the network management side.

Use the path method to create the Client service path. After the creation is completed, the optical layer OCh path will be automatically generated, reducing the secondary education of path creation.

The creation or search of a new path must be realized only when the path at the upper level of the service layer already exists.

If the automatically calculated route is different from the planned route, you can set the "must pass through node" or "must pass through node" to restrict the route.

If the software version carried on the replaced main control board is higher than the device version, you need to clear the main control library first, and then downgrade the main board software to the same version as the device.

If the software version locked on the replaced main control board is lower than the device version, you need to upgrade the software on the main control board to the same version as the device

When the main control board has 1+1 hot backup, under normal switching conditions, the replacement of the main control board will not affect the business.

After receiving the alarm, the SOM obtains the OCh path corresponding to the alarm and adds it to the management path to be optimized.

The downstream power detection unit (OA) detects that the line attenuation deviation exceeds the threshold and reports an alarm to its local SCC board.

55. Which of the following description regarding the principle of automatic protection switching of the standard SSM protocol is correct? (Multiple Choice)

The network element broadcasts the clock quality information of the synchronization source to the downstream station through the s1 byte.
