The SPECTRA-155 Auxiliary Section/Line Interrupt Status register replicates
section and line interrupts that can be found in the CRU, CSU, RSOP and RLOP
registers. However, unlike the above interrupt register bits that clear on reads,
the SPECTRA-155 Auxiliary Section/Line Interrupt Status register bits do not
clear when read. To clear these registers bits, a logic one must be written to the
register bit.
LOSI:
The LOSI bit is set high when loss of signal is declared or removed.
LOFI:
The LOFI bit is set high when loss of frame is declared or removed.
LAISI:
The LAISI bit is set high when line LAIS is declared or removed.
LRDII:
The LRDII bit is set high when line RDI is declared or removed.
OOFI:
The OOFI bit is set high when out of frame is declared or removed.
RDOOLI:
The RDOOLI bit is the receive data out of lock interrupt status bit. RDOOLI is
set high when the DOOLV bit of the SPECTRA-155 CRSI Clock Recovery
Control, Status and Interrupt register changes state. DOOLV is a logic one if
