質問 12

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

（A）The network element first selects the clock with the highest quality level from the available clock sources as the synchronization source according to the clock source priority table.

（B）The network element broadcasts the clock quality information and clock source ID of the synchronization source to the downstream station through the S1 byte, and reversely notifies the upstream station along the direction of the synchronization source through the S1 byte that the clock quality from this network element is "unavailable Synchronize".

（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 of the synchronization source to the downstream station through the s1 byte. And through the S1 byte, the clock quality from the local network element is "not available for synchronization" to notify the Shangxi site in the reverse direction along the direction of the synchronization source.
