Easily To Pass New Huawei H31-311_V2.5 Dumps with 200 Questions [Q44-Q66]

NO.44 On OSN Series transmission devices, ethernet ports cannot access tagged and untagged frames at the same time

NO.45 In MSP networking, when the optical fiber is connected between sites, the east light plate of the site is connected to the west light plate of the downstream site, and these stations are connected in turn to form a ring. In this case, the direction from the toko plate of the site to the wine light plate of the downstream station is the direction of the main ring, and the direction of forming the ring is the direction of service.

NO.46 According to the formula “ODUk rate = 239/(239k) x STMN frame rate”, ODU4 The rate is equal to 239/235× STMN frame rate.

NO.47 Which of the following are the components of the WDM system summer with N glass lengths? (Multiple choice).

NO.48 Which of the following is the functional unit that provides a high-speed signal interface and processes the corresponding signal?

NO.49 PDM uses a polarization beam splitter to divide the laser into two vertical directions: x and y.

NO.50 The OTN signal has a fixed pad period, the same frame period as the SDH signal.

NO.51 Suppose 2 VC-12 time slots need to be bound to the VCTRUNK1 of the N2EFS4 board. When there are 8 VC4 slots on the N2EFS4 board, which of the following slots meets the requirements?

NO.52 Which overhead below 112 is not ODUk overhead?

NO.53 LCK insertion takes precedence over AIS insertion. That is, if the user configures LCK insertion and the conditions for automatic AS insertion are met, the LCK is inserted.

NO.54 Optical monitoring channel is used for monitoring of WDM optical transmission systems. In the UU-T recommendation, it is preferable to use a 1510 nm wavelength of the a “) rate.

NO.55 Which of the following clock operating modes supports the ITU-T G.781 standard? (Multiple choice).

NO.56 OTM nr.m consists of up to n ” multiplexed channels and does not support non-channel-related overhead. The letter “r” indicates a decrease in functionality.

NO.57 The segment overhead of STM-4 is () bytes/frame.

NO.58 Which of the following statements about the MSP ring is correct? (Multiple choice).

NO.59 EPL services use ports and bandwidth exclusively, and different users may need to share resources. Which of the following methods can be used to isolate user data?

NO.60 Linear MSP (LMSP) has two modes: 1+1 and 1:1. Additional services can only be configured for the protection channel in 1:1 mode of the LMSP.

NO.61 Which of the following is not a nonlinear effect?

NO.62 The backplane has two 48V power cords, and each board gets two -48V power supplies from the backplane. After combining the power supply via diodes, the various voltages required for each component are obtained by means of a DC/DC power module and a linear mane swap.

NO.63 K1 and K2 bytes can send APS switching signaling or indicate that the multiplexed segment signal is invalid.

NO.64 In the SDH optical synchronous transmission system, which of the following bytes is used to transmit the quality and weight and usage information of the clock source?

NO.65 Single-fiber bidirectional WDM systems use only one optical fiber to transmit optical signals in both directions at the same time. Light signals in both directions should be arranged at different wavelengths.

NO.66 Which of the following are the service board types for MSTP devices? (Multiple choice).
