In 2.5G MSP ring composed of four MSTP sites, when protection switch occurs, which of the following statements about the alarm report are correct?

• A.  PS alarm is reported on the tributary board.
• B.  Report the APS-INDI alarm on the system control board.
• C.  Report the APS-INDI alarm on the circuit board.
• D.  APS-INDI alarm is reported on the XCS board.

SF is a signal failure event and SD is a signal degradation event. Both the SF and SD events are conditions for triggering protection switching, but whether the SD time is used as a trigger switching condition can be set by the user.

• A.  TRUE
• B.  FALSE

The single-fiber bidirectional WDM system uses only one fiber to transmit optical signals in both directions simultaneously. The optical signals in both directions should be arranged at different wavelengths.

• A.  TRUE
• B.  FALSE

What should be paid attention to when configuring extended ECC? (Multiple Choice)

• A.  When setting the ECC extended mode remotely, you must ensure that the settings are correct in order. Otherwise, the unmanaged network element will not automatically resume communication with the network management system and must be reset to the site.
• B.  It is not recommended to set the gateway NE as the server. It is recommended to set the NE closest to the gateway NE as the server NE.
• C.  Avoid communication by extended ECC mode between each subnet gateway network element.
• D.  The ECC extension mode of the remote NE must be modified first, and then the ECC extension mode of the gateway NE is modified.

After starting the extended SSM protocol, in addition to determining the clock quality level and priority, the clock ID is also determined. After receiving the clock signal with the ID, the network element considers that the source is unavailable if it is judged to be the clock signal sent by the station. In this way, even after passing through multiple sites, the network element can still recognize the clock signal sent by itself, preventing the formation of a timing loop.

• A.  TRUE
• B.  FALSE
