The rate of SF64 and SL64 boards is STM54. Therefore, the two plates can be interconnected.
Forced switching, fiber switching, manual switching and motion switching are decreased in order of priority.
Which of the following alerts does not trigger an AU-AIS alert?
PDM uses a polarization beam splitter to divide the laser into two vertical directions: x and y.
Coherent receiver technology uses a local oscillator laser with the same frequency as the received signal to perform coherent processing and recover () information from the received signal. (Multi-quality selection.)
If a network port that supports autonegotiation is connected to a network port that does not support autonegotiation, you can interconnect in both half-duplex and full-duplex modes.
MSP is a network-level protection scheme. MSF does not directly protect services, and MSP switching and recovery are not affected even if there is no service on the MSP ring.
The scope of management of OMSn is the path from the input optical port on the multiplexer unit of the sending site to the output optical port on the multiplexer unit of the receiving site, called the optical multiplexing segment (OMS) path.
When the ACT indicator of the SDH board is off, it means that the board has a hardware failure and cannot be used.
Which of the following statements about the MST functional module is correct? (Multiple choice).
