NEW QUESTION 183
In the network management planning, which of the following descriptions is correct (multiple choice)

Equivalence factor = resources occupied by physical network elements or ports / system resources occupied by equivalent network elements; virtual network elements do not calculate management capabilities; pre-configured network elements are equivalent to virtual network elements.

Centralized deployment scheme is recommended for network management deployment planning. Only consider the use of a distributed deployment solution when the customer strongly requires it.

In the deployment planning of the network management subsystem, it is necessary to determine the network element manager subsystem to be installed according to the network element series. For example, if you need to use the Corba northbound interface, you need to install the Corba northbound subsystem.

Among other requirements, if the client is running on the server side at the same time, the management ability will be reduced by 60%, so it is recommended that the client and server be run separately.

The 20th wave LSX WDM side light emission is too small

Wave 20 LSX wavelength shift

The insertion loss of the 20th channel corresponding to M40 is too large

The RX port of the 20th wave LSX has an additional 5dB fixed light attenuation

NEW QUESTION 185

Which of the following statements about OTN overhead is correct? () (multiple choice)

5 consecutive frames in the SM/TCMi/PM overhead field (the 5th bit of the 3rd byte) The bit value of BDI is “1”, which will generate BDI

BIP-8 error codes in SM, PM, TCM monitor errors in different levels and areas in OTN

In the OTN frame structure, only SM overhead has IAE and BIAE functions

Both TCM and PM have ODUK-LCK, ODUK-OCI, ODUK-AIS three maintenance information

NEW QUESTION 187
The following is wrong about the position of the dispersion module in the signal flow.

If there is an OAU board, DCM is placed between OAU’s TDC/RDC

If there is only one OBU board, the DCM is placed after the OBU

If there are two OBU boards, the DCM is placed between the two OBUs

The OTM station usually pre-fills 20KM DCM before sending OBU

NEW QUESTION 188
The OSN8800 device newly expanded a TN55ND2 board, and it was found that the board could not go online. The following reasons are impossible:

SWDL_AUTOMATCH_INH alarm exists in the main control

SWDL_PKG_ NOBDSOFT alarm exists in the main control

SWDL_CHGMNG_NOMATCH alarm exists in the main control

NEW QUESTION 189
Preparation conditions for single-site commissioning of transmission equipment include (multiple choices)

Whether the hardware installation is qualified

Does the power supply have

Whether the related optical fiber and cable are installed in place

Make sure that the network management program installed on the laptop is normal

NEW QUESTION 190
The following clock networking optimizations are wrong:

Under the non-SSM switching protocol, the clock network can only be configured as one-way and cannot form a loop.

For PDH, ITU-T stipulates that 4 consecutive odd frames sa4~sa8 in 2M bit signal TS0 are used to transmit quality information, and SDH uses S1 byte b5-b8 to transmit the same quality information. SDH equipment can automatically extract SSM information from the 2Mhz external clock signal provided by the BITS equipment, so as to know the quality level of the timing signal.

Under the standard SSM switching protocol, the clock can be configured as bidirectional, but it must not be configured as a ring. Enable the extended SSM protocol to solve the clock loop problem by assigning a clock ID to the clock source.

Timing reference clock transmission link, requires that at most N=20 network elements, the transit office clock must be introduced for clock reshaping and regeneration (high-quality clocks are serialized), up to K=10 transit office clocks, clocks The maximum number of G.813 clocks on the link does not exceed 60.

NEW QUESTION 191
After the OTN device to the storage device is opened, the actual service rate is less than 20% of the interface rate. Possible reasons (multiple choice)
