For the SSM protocol, which of the following statements are correct? (Multiple choice)

A.When the extended SSM protocol is started, the clock network can be configured in both directions and can be looped.
B.When the SSM protocol is not enabled, the clock network can only be configured as one-way and cannot be looped.
C.Whether to start the SSM protocol has little effect on the clock network.
D.When the standard SSM protocol is started, the clock network can be configured in both directions but cannot be looped.

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

A.The network element broadcasts the clock quality information of the synchronization source to the downlink site through the s1 byte. And reverse notice the uplink site by the S1 byte in the direction of the synchronization source that the clock quality from the local network element is "not available for synchronization".
B.According to the clock source priority table, the network element first selects the clock with the highest quality level from the available clock sources as the synchronization source.
C.If there are multiple clock sources with the highest quality level, the network element selects the clock with the highest clock priority as the synchronization source.
D.The network element broadcasts the clock quality information and the clock source ID of the synchronization source to the downlink site through the S1 byte, and reverse notices the uplink site that the clock quality from the local network element is "not available for synchronization" by the S1 byte in the direction of the synchronization source.

The OSN 1800V supports the following packet protection features:

The following description of the Directioned scenario, which is correct? (Multiple choice)

A.The wavelength carrying the local service can be transmitted to fixed direction.
B.Directioned scenes are applied to networks that are not ASON.
C.If the current path needs to be adjusted, you must inbound to adjust the fiber connection of the network.
D.When the service needs to be adjusted, or the working path is faulty, the optical crossover can be manually configured to implement flexible scheduling of services.

In general, which of the following operations will cause a short interruption in monitoring of existing network devices? (Multiple Choice)
