Alarms/Errors Overview

GFP-tHEC-UNCORR (GFP - type Header Error Check - Uncorrectable)
RX
: Indicates that two or more bit errors have been detected in the
Type header (tHEC, PTI, PFI, EXI, and UPI).
TX
(requires client data frame generation): Generates a “Walking 11”
pattern to hit all consecutive 2 bits applicable to the bits covered by the
tHEC, PTI, PFI, EXI and UPI.

GFP-eHEC-CORR (GFP - extension Header Error Check - Correctable)
is only available with GFP-F when EXI is set to
Linear
.
RX : Indicates that only one bit error has been detected in the Extension
header (eHEC, CID and Spare).
TX (requires client data frame generation): Generates a “Walking 1”
pattern to hit all applicable bits covered by the eHEC, CID and Spare.

GFP-eHEC-UNCORR (GFP - extension Header Error Check -
Uncorrectable) is only available with GFP-F when EXI is set to
Linear
.
RX : Indicates that two or more bit errors have been detected in the
Extension header (eHEC, CID and Spare).
TX (requires client data frame generation): Generates a “Walking 11”
pattern to hit all consecutive 2 bits applicable to the bits covered by the
eHEC, CID and Spare.

GFP-SB-CORR
(GFP - Superblock Correctable) is available with GFP-T.
RX : Indicates that bit error has been detected in the CRC-16 word of
the superblock. A received SB Correctable (Pre) error counts as one
error while SB Correctable (Post) counts as two errors.
TX
:
GFP-SB-CORR (Pre) generates a “Walking 1” pattern to include a
single bit error in the CRC-16 word of the superblock.
GFP-SB-CORR (Post) generates in the payload of the superblock, a
“Walking 1” pattern to include two separate errors in one superblock
separated by 43 bits.
