Regarding the TTX board, which of the following statements is correct?
- A . In essence, the TTX board is not a 100G tributary board, but it requires a single-slot 100G crossover capacity
- B . 8800 T64/T32 universal subrack can support TTX single board
- C . This board belongs to the tributary board and can access 100G client-side services
- D . TTX can do ODU4 particle electrical crossover with NS4
The switching mode of 1:1 linear multiplex section can be single-ended switching or double-ended switching.
- A . True
- B . False
In order to meet the specified synchronization quality requirements, corresponding requirements must be made on the network for synchronous transmission, and the specified networking rules must be followed during network planning. Which of the following is wrong?
- A . In one clock transmission direction, the number of stations between the transit office clocks cannot exceed 30
- B . The number of switching office clocks cannot exceed 10
- C . The total number of devices in one direction cannot exceed 60
The clock ID can solve the possible timing loop problem. In the following networking, in order to completely solve the clock loop, how many clock IDs need to be set in total?
- A . 3
- B . 4
- C . 6
- D . 7
Which reason for the OA_LOW_GAIN alarm is wrong?
- A . The input optical power of the board is too high
- B . The insertion loss between the TDC and RDC optical ports is too large (only for the OAU board)
- C . The board that reported this alarm is faulty
- D . The gain of the optical amplifier board is set too low
Which of the following statements about the delay test is wrong?
- A . The delay is divided into the delay of the store-and-forward device and the delay of the bit-forward device. Huawei devices are all store-and-forward devices
- B . The timing starts from the entry of the first bit of the data frame, and ends when the first bit of the data frame appears on the output terminal P. The time difference between the two is the delay of the bit forwarding device
- C . The timing starts from the entry of the first bit of the data frame, and ends when the first bit of the data frame appears on the output terminal P. The time difference between the two is the delay of the bit forwarding device
- D . During the delay test, the frame rate can be greater than the throughput
For a point-to-point network, set the TIM mode on the network management system to path terminal sink "only compare DAPI".
- A . True
- B . False
Which of the following options is not an advantage of EDFA optical amplifiers?
- A . High gain
- B . High output power
- C . The working optical bandwidth is wide
- D . Gain Flattening
The indicator light of OptiXtrans E6600 LOSn is red and blinks once every 3 seconds. Which of the following is it?
- A . The optical port of the single board reports the R_LOS alarm
- B . The optical port of the single board reports the MS_RDI alarm
- C . The board is not in place
- D . The optical module is not in place
In the path search process of the U2000 network management, the path search management module first scans the cross-connections of each network element, constructs sub-paths according to the cross-connections of adjacent network elements, and tries to merge these sub-paths at the same time. Which of the following sub-paths is legal?
- A . Subpaths form a loop
- B . The path does not pass through the fiber
- C . The original destination is not the end point of the subpath or the optical port of the subnet
- D . The sub-path terminates on the pre-configured network element
