NEW QUESTION 12
The NG WDM two-dimensional ROADM site can use the WSMD9 single board, and its signal flow is an optical signal that is connected to the main optical channel from the "IN" optical port. The RDU (ROADM Demix Unit) optical module broadcasts nine identical optical signals, which are output from the "DM1~DM8" and "ECPO" optical ports respectively. One of the signals is localized by the splitter board, and the other eight signals are dispatched to the other eight directions. Each wave of the main optical channel is connected from the "EXPI" optical port. The multiplexed or single-wave optical signal that needs to be inserted locally is input through the "AM1"~"AM8" optical port.

• A. TRUE
• B. FALSE

Answer: A

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

NEW QUESTION 18
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 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.
• B. 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".
• 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. 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.
