BDI (Backward Defect indication) for FlexO, indicates that the BDI bit
in the PM overhead field (byte 3, bit 5) of ODUC #1 is “1” for at least
15 consecutive frames. In TX, generates a “1” in the BDI (byte 3, bit 5)
of the PM overhead field of the ODUC #1 continuously.
BDI (Backward Defect Indication) for FlexO OTUCn, indicates that the
BDI bit in the SM overhead field (byte 3, bit 5) of the OTUC #1 is “1” for
at least 15 consecutive frames. In TX, generates “1” for the BDI bit in
the SM overhead field (byte 3, bit 5) of the OTC #1 continuously.
BDI (Backward Defect indication) for ODU, indicates that the BDI bit in
the PM overhead field (byte 3, bit 5) is “1” for at least 5 consecutive
frames. In TX, generates a “1” in the BDI (byte 3, bit 5) of the PM
overhead field continuously.
BDI (Backward Defect Indication) for ODU-TCM, indicates that the BDI
bit in the TCM overhead field Byte 3, bit 5 is “1” for at least 5
consecutive frames. In TX, generates a "1" in the BDI bit of the TCM
overhead field (byte 3, bit 5) continuously.
BDI (Backward Defect Indication) for OTU, indicates that the BDI bit in
the SM overhead field (byte 3, bit 5) is “1” for at least 5 consecutive
OTU frames. In TX, generates “1” for the BDI bit in the SM overhead
field (byte 3, bit 5) continuously.
BIAE (Backward Incoming Alignment Error) for FlexO OTUCn,
indicates that the BEI/BIAE bits in the SM overhead field (byte 3, bits
1 to 4) are “1011” for at least 3 consecutive frames. In TX, generates
“1011” for the BEI/BIAE bits in the SM overhead field (byte 3, bits 1 to 4)
of OTUC continuously.
BIAE (Backward Incoming Alignment Error) for ODU-TCM, indicates
that the BEI/BIAE bits in the TCM overhead field Byte 3, bits 1 to 4 are
“1011” for at least 3 consecutive frames. In TX, generates "1011" in the
BEI/BIAE bits of the TCM overhead (byte 3, bits 1 to 4) continuously.
