The SPECTRA-155 Auxiliary Path Interrupt Status #2 register replicates path
interrupts that can be found in the RPOP #2 and SPTB #2 registers. However,
unlike the RPOP #2 and SPTB #2 interrupt register bits that clear on reads,
these register bits do not clear when read. To clear these registers bits, a logic
one must be written to the register bit.
TIMI:
The path trace identifier mismatch interrupt status bit (TIMI) is set high on
changes in the path trace identifier mismatch status.
TIUI:
The path trace identifier unstable interrupt status bit (TIUI) is set high on
changes in the path trace identifier unstable status (mode 1).
LOMI:
The loss of multiframe interrupt status bit (LOMI) is set high on changes in
the loss of multiframe status.
LOPI:
The loss of pointer interrupt status bit (LOPI) is set high on the change of loss
of pointer status.
PSLMI:
The path signal label mismatch interrupt status bit (PSLMI) is set high on
changes in the path signal label mismatch status.
