Bit Name
Default
Bit No.
Type
When CRC Multi-Frame is synchronized, once the accumulated CRC-4 errors are not less than 915 ( ≥ 915) in a 1 second fixed window, an
= 0: No Excessive CRC-4 Error event is detected.
= 1: The Excessive CRC-4 Error event is detected.
This bit will be cleared if a ’1’ is written to it.
= 0: There is no status change on the C2NCIWV bit (b4, E1-04FH).
= 1: There is a transition (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the C2NCIWV bit (b4, E1-04FH).
This bit will be cleared if a ’1’ is written to it.
= 0: There is no status change on the OOSMFV bit (b3, E1-04FH).
= 1: There is a transition (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the OOSMFV bit (b3, E1-04FH).
This bit will be cleared if a ’1’ is written to it.
