Which of the following is the multiplexing mode of SDH?
Which of the following are the main advantages of SDH? (Multiple Choice)
The interval between two adjacent pointer justification events is at least ( ) frames.
According to ITU-T recommendations, the requirement that the MSP switching time should be within 50 ms is conditional. For example, the number of NEs on an entire ring network is less than 16.
Forced switching, fiber cut switching, manual switching, and exercise switching are in the descending order of priority.
The pointer is used for alignment and indicates the start position of VC-n in the corresponding AU or TU frame. In this way, the receive end can correctly remove the corresponding VC from the STM-N, and then split the VC and C encapsulation to separate low-rate signals, such as PDH. That is, low-rate tributary signals can be directly dropped from the STM-N signal.
Which of the following factors determines that the optical signal-to-noise ratio (OSNR) at the receive end decreases to a certain extent After signals are transmitted for a certain distance in a WDM system, the optical signal-to-noise ratio (OSNR) at the receive end decreases to a certain extent. Which of the following is the main cause?
The last 256 columns in the OTN frame structure are FEC areas, which are used for forward error correction.
Which of the following is the frame structure of STM-16?
Frame-Mapped GFP (GFP-F) is a processing mode oriented to data coding blocks (such as Fiber Channel and ESCON).
