問題 #1

Which of the following descriptions are correct for error alarms (multiple choice)

A. FEC_BEF_COR_ER enables the FEC function to be effective, FEC error rate before error correction, indicating the error statistics of the received OTUk signal (including OTUk overhead), and the error rate before error is not zero, indicating the error rate introduced by the transport layer The bit error may have affected the OTUk signal.
B. FEC_AFT_COR_ER enables the FEC function to be valid. The error rate after FEC error correction indicates the error statistics of the OTUk signal (including OTUk overhead) after FEC encoding and error correction. The error after correction is not zero, which means transmission The bit error introduced by the layer may have affected the OTUk signal.
C. OTUk_ES (OTUk_BEE ), ODUk_PM_ES (ODUk PM_BBE) are OTUk/ODUk errored seconds (background error block), the count is the error count of the OTUk/ODUk signal that is counted, non-zero means OTUk/ODUk signal The second in which a bit error occurred (the number of errored blocks).
D. OTUk_SES and ODUk_PM_SES are OTUk/ODUk severely errored seconds, and the count is not zero, indicating that the OTUk/ODUk signal has generated a large bit error in seconds (1 second counting error bits more than 15% of the maximum transmission byte)

問題 #2

After the AM function of the microwave equipment is enabled, the signal level of the high modulation mode is lower than that of the low modulation mode.

A. TRUE
B. FALSE

問題 #3

SPC (Software Permanent Connection). It is the business connection between PC and SC. The user to the network part is directly configured by the network management management plane, and the connection of the network part is initiated by the network management management plane to the ingress network element control plane, which is completed by the ingress network element control plane through signaling

A. TRUE
B. FALSE

問題 #4

The following is the network parameter planning of an engineer's network management server, the correct one is (multiple choice)

A. Stand-alone system (Windows) IP address planning: IP address: 129.9.1.1/255.255.255.0; gateway: 123.9.1.254
B. Network management server host name: Server123-
C. A network server with 2000 equivalent network elements, and the planned bandwidth for managing network elements is 3.02Mbit/s
D. A network with 2000 equivalent network elements, a collection period of 15 minutes, and 7 days of performance data, the planned performance database size is 80GB

問題 #5

OAU gain is continuously adjustable, and the noise figure (NF) is different under different gain conditions, generally the larger the gain, the smaller the noise figure

A. TRUE
B. FALSE
