Pointer justification is caused by asynchronous clocks on two interconnected NEs. When one NE reports a positive pointer justification event, the other NE reports a negative pointer justification event.
A. TRUE
B. FALSE
What information is conveyed by SSN1SL16A01, a board bar code of NG-SDH equipment?
A. Board version
B. Board name
C. Board feature code

Which of the following are true about AU pointer justification?
A. The value of the AU-FTR pointer is in the last ten bits of the HI and H2 bytes. Therefore, the value range is 0 to 1023.
B. AU-FTR points to the J0 byte.
C. The AU pointer is adjusted because the clocks of an upstream NE and a downstream NE are asynchronous.
D. When an NE detects all "l"s in the received HI and H2 bytes, the NE reports the AU-AIS alarm.
On a normal network, clock protection switching fails after the clock synchronization path is interrupted. As a result, lots of pointer justification events occur on related NEs. What are the possible causes for the failure of clock protection switching?
A. Incorrect fiber connections between boards
B. Optical power is incorrect.
C. The clock tracing modes are incorrect.
D. The network-wide clock protection switching protocols are incorrectly configured.
E. Hardware faults
Network-level protection switching must be tested during system commissioning for OptiX OSN 3500. Which of the following will trigger protection switching on a ring network?
A. Perform a loopback (LB) test.
B. Shut down the laser.
C. Disconnect fibers.
D. Power off the equipment.
To test the communication status of an NE, right-click the NE on the Main Topology of the U2000 and choose Ping.
A. TRUE
B. FALSE
Which of the following is true about the ALM_GFP_dCSF alarm?
A. The alarm indicates the out-of-frame state of generic framing procedure (GFP) frames.
B. The alarm indicates loss of GFP client signals.
C. The alarm indicates GFP protocol failure.
D. The alarm indicates inconsistency in GFP working modes.
Generally, what is the maximum number of NEs on an ECC subnet, to ensure communication performance of an ECC subnet?
A. 64
B. 96
C. 128
D. 256
