Alarms/Errors Overview

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
(requires client data frame generation): 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 222).
