The SPECTRA-155 Auxiliary Path Enhanced Interrupt Status register replicates
path interrupts that can be found in the RPOP #1, RPOP #2 and RPOP #3
registers. However, unlike the RPOP #1, RPOP #2 and RPOP #3 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.
EPRDII#1, EPRDII#2, EPRDII#3:
The enhanced path remote defect indication interrupt (EPRDII) bits are set
high when the corresponding RPOP #n detects a change in the enhanced
path remote defect state.
TIU2I#1, TIU2I#2, TIU2I#3:
The path trace identifier unstable mode 2 interrupt status bit (TIU2I) is set
high on changes in the path trace identifier unstable status for mode 2
operation.
PAISCONI:
The path AIS concatenation interrupt (PAISCONI) bit is set high when the
SPECTRA-155 is configured for STS-3c (STM-1/AU4) mode and there is a
change of the path AIS concatenation state. Please refer to the RPOP #1
Status and Control register for the new path AIS concatenation state.
LOPCONI:
The loss of pointer concatenation interrupt (LOPCONI) bit is set high when
the SPECTRA-155 is configured for STS-3c (STM-1/AU4) mode and there is
a change of the pointer concatenation state. Please refer to the RPOP #1
Status and Control register for the new pointer concatenation state.
