Bit Name
Default
Bit No.
Type
If the 4-bit Sa6 codeword of a CRC Sub Multi-Frame is matched with ‘0010’ or ‘0011’, the Network Terminal CRC Error event is generated.
= 0: No NT CRC Error event is detected.
= 1: The NT CRC Error event is detected.
This bit will be cleared if a ’1’ is written to it.
If the 4-bit Sa6 codeword of a CRC Sub Multi-Frame is matched with ‘0001’ or ‘0011’, the Network Terminal Far End Block Error event is gener-
= 0: No NT FEBE Error event is detected.
= 1: The NT FEBE Error event is detected.
This bit will be cleared if a ’1’ is written to it.
When CRC Multi-Frame is synchronized and any of the CRC error indication (E1 or E2) bits is received as a logic 0, a far end block error event is
= 0: No Far End Block Error (FEBE) event is detected.
= 1: The Far End Block Error (FEBE) event is detected.
This bit will be cleared if a ’1’ is written to it.
= 0: There is no status change on the RAICRCV bit (b, E1-04FH,...).
= 1: There is a transition (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the RAICRCV bit (b2, E1-04FH,...).
This bit will be cleared if a ’1’ is written to it.
= 0: There is no status change on the CFEBEV bit (b, E1-04FH,...).
= 1: There is a transition (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the CFEBEV bit (b, E1-04FH,...).
This bit will be cleared if a ’1’ is written to it.
= 0: There is no status change on the V52LINKV bit (b, E1-04FH,...).
= 1: There is a transition (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the V52LINKV bit (b, E1-04FH,...).
This bit will be cleared if a ’1’ is written to it.
