terminates when fewer than two far-end los indicators are reported out of six consecutively
received reports.
• Far-end loss of margin (lom-fe): This defect occurs when a lom detected at the far end is reported
in at least four of six consecutively received far-end lom indicator reports (Table 9-8). A lom-fe
terminates when fewer than two far-end lom indicators are reported out of six consecutively
received reports.
• Far-end loss of RMC (lor-fe): This defect occurs when a lor detected at the far end is reported in at
least four of six consecutively received far-end lor indicator reports (Table9 -8). A lor-fe terminates
when fewer than two far-end lor indicators are reported out of six consecutively received reports.
11.3.1.5 Initialization primitives

• Full initialization (full_init): This primitive occurs each time the FTU-O transitions from the
O-SILENT to the O-INIT/HS state (see Figure 12-4).
• Failed full initialization (failedfull_init): This primitive occurs each time the FTU-O transitions from
the O-INIT/HS to the O-SILENT state and each time the FTU-O transitions from the O-INIT/TRAIN to
the O-DEACTIVATING1 state following a full_init primitive (see Figure 12-4).
• Fast initialization (fast_init): This primitive occurs each time the FTU-O transitions from the
O-DEACTIVATING2 to the O-INIT/TRAIN state (see Figure 12-4).
• Failed fast initialization (failedfast_init): This primitive occurs each time the FTU-O transitions from
the O-INIT/TRAIN to the O-DEACTIVATING1 state following a fast_init primitive (see Figure 12-4).
11.3.1.6 Near-end OLR/FRA primitives
• Successful bit swap (success_BSW): This primitive occurs each time the bit loading on the data
symbols (NOI or DOI) is changed through the near-end initiating an OLR type 1 for bit swapping or
an OLR type 2 for bit swapping (see Table 11-9).
• Successful autonomous SRA (success_SRA): This primitive occurs each time the bit loading on the
data symbols (NOI or DOI) is changed through the near-end initiating an OLR type 1 for
autonomous SRA or an OLR type 2 for autonomous SRA (see Table 11-9).

• Successful FRA (success_FRA): This primitive occurs each time the bit loading on the data symbols
(NOI or DOI) is changed through the near-end initiating an FRA (see Table 11-9).
• Successful RPA (success_RPA): This primitive occurs each time the set of RMC subcarriers or the bit
loading of RMC subcarriers is changed through the near-end initiating an OLR type 4 for RPA (see
Table 11-9).
• Successful TIGA (success_TIGA): This primitive occurs each time the bit loading on the data
symbols (NOI or DOI) is changed through the near-end initiating an OLR type 3 for TIGA (see
Table 11-9).

11.3.1.7 Far-end OLR/FRA primitives
• Successful bit swap (success_BSW_FE): This primitive occurs each time the bit loading on the data
symbols (NOI or DOI) is changed through the far-end initiating an OLR type 1 for bit swapping or an
OLR type 2 for bit swapping (see Table 11-9).

• Successful autonomous SRA (success_SRA_FE): This primitive occurs each time the bit loading on
the data symbols (NOI or DOI) is changed through the far-end initiating an OLR type 1 for
autonomous SRA or an OLR type 2 for autonomous SRA (see Table 11-9).
• Successful FRA (success_FRA_FE): This primitive occurs each time the bit loading on the data
symbols (NOI or DOI) is changed through the far-end initiating an FRA (see Table 11-9).
• Successful RPA (success_RPA_FE): This primitive occurs each time the set of RMC subcarriers or
the bit loading of RMC subcarriers is changed through the far-end initiating an OLR type 4 for RPA
(see Table 11-9).
