NO.41 Which of the following statements about overhead bytes is incorrect?

A1 and A2 are framed bytes” These bytes are used to separate STM-1 frames in the signal stream. .

J0 is the regenerator part trace byte. This byte is used to resynch the send segment access point identifier so that the receiving end can verify its continuous connection to the specified sender.

B1 is better than holding interleaved parity 8 (BIP-8). This byte is used to monitor for bit errors in the regenerator section layer.

E1 and E2 are wired bytes. These bytes are used to provide a voice channel for order line connections.

NO.42 When the sender detects that the b6-b8 of the K2 byte is 110, it means that the sender has reported an alarm ().
