Alarms/Errors

GFP-SB-UNCORR (GFP - Superblock Uncorrectable) is available with
GFP-T.
RX: Indicates that two or more bit errors have been detected in the
CRC-16 word of the superblock. Note that if two errors are spaced by
exactly 43 bits, they will not be reported as uncorrectable.
TX: Generates a “Walking 11” pattern to include two consecutive
errors in the CRC-16 word of the superblock.

GFP-10B_ERR (GFP - 10B_Error) is available with GFP-T.
RX: Indicates that a10B_ERR code has been detected in the payload of
the superblock.
TX: Generates a 10B_ERR code over the payload of the superblock as
defined in ITU G.7041.

GFP-pFCS (GFP - payload Frame Check Sequence)
RX: Indicates that at least one bit error has been detected in the
payload.
TX
1
: Generates a “Walking 1” pattern to hit all 32 bits of the pFCS only.
Only available with Ethernet (flex/GFP-F) client when the CDF pFCS
check box is selected (refer to GFP-F/GFP-T on page 90).
1. Requires client data frame generation.
