- A. MS-AIS
- B. R-LOS
- C. B2-EXC
- D. AU-LOP
Which of the following statements about overhead bytes is incorrect?
- A. E1 and E2 are orderwire bytes. These bytes are used to provide a voice channel for orderwire connections.
- B. B1 is bit interleaved parity-8 (BIP-8). This byte is used to monitor bit errors at the regenerator section layer.
- C. J0 is a regenerator section trace byte. This byte is used to repeatedly transmit a section access point identifier, so that the receive end can verify its continuous connection to the specified transmit end.
- D. A1 and A2 are framing bytes. These bytes are used to separate STM-1 frames in a signal flow.
Which of the following is the basic requirement of a DWDM system on a light source?
- A. The dispersion tolerance is low.
- B. The output wavelength is stable.
- C. The transmit power is high.
- D. The direct modulation method is used.
The receive end performs BIP-8 check for the unscrambled STM-16 frame. If the BIP-8 check result XOR the value of the B1 byte contained in the following STM-16 frame is 10001100, it indicates that ( ) bit error blocks exist in the STM-16 frame.
- A. 5
- B. 3
- C. Unclear
- D. 6
