ODUk Automatic Protection Switching and Protection Control Channel
The APS/PCC monitor declares the APS/PCC field to be valid after n consecutive matches and declares
the APS/PCC field invalid after n consecutive mismatches, where n has a value of 1 through 8 and is set
through register bits ODUk_APSPCC_MAT[2:0]. The APS/PCC monitor stores the valid APS/PCC
field, as indicated by a high live bit ODUk_APSPCCL, in ODUk_APSPCC[1:0][15:0]. Every change of
the live bit sets the status bit ODUk_APSPCCS and the status bit with its respective mask bit
ODUk_APSPCCM create a maskable interrupt.

ODUk Fault Type and Fault Location Reporting Channel (FTFL)
The FTFL monitor stores the FTFL bytes in the stack ODUk_FTFL[127:0][15:0] at locations pointed to
by MFAS. The microprocessor may point to any byte in the stack by initializing the microprocessor
stack pointer ODUk_FTFL_MPNT[4:0]. Each microprocessor read of or write to the stack
automatically increments the microprocessor stack pointer. (Writes to the stack are for testing purposes
only.)
The live bits ODUk_FTFL_FOPIL (forward operator identifier), ODUk_FTFL_FOPSL (forward
operator-specific), ODUk_FTFL_BOPIL (backward operator identifier), and ODUk_FTFL_BOPSL
(backward operator-specific) indicate whether the respective fields stored in ODUk_FTFL[127:0][15:0]
are valid (1) or invalid (0). A change of any field state sets the respective status bit ODUk_FTFL_FOPIS
(forward operator identifier), ODUk_FTFL_FOPSS (forward operator-specific), ODUk_FTFL_BOPIS
(backward operator identifier), and ODUk_FTFL_BOPSS (backward operator-specific). The status bits
with their respective interrupt mask bits ODUk_FTFL_FOPIM (forward operator identifier),
ODUk_FTFL_FOPSM (forward operator-specific), ODUk_FTFL_BOPIM (backward operator
identifier), and ODUk_FTFL_BOPSM (backward operator-specific) create maskable hardware
interrupts.
An FTFL trace is valid after n consecutive matches (that is, debounced n times), where n has a value of
1 through 8 and is set through register bits ODUk_FTFL_MAT[2:0]. An FTFL trace is invalid after m
consecutive mismatches, where m has a value of 1 through 8 and is set through register bits
ODUk_FTFL_MIS[2:0].
