MONx_SYNCI:
The Monitor Synchronization Interrupt Status registers indicate synchronization interrupts for
each of the 48 STS-1 paths.
PRGM Monitor Synchronization Interrupt Status register, N = 0.
PRGM Aux2 Monitor Synchronization Interrupt Status register, N = 1.
PRGM Aux3 Monitor Synchronization Interrupt Status register, N = 2.
PRGM Aux4 Monitor Synchronization Interrupt Status register, N = 3.
The Monitor Synchronization Interrupt Status Interrupt (MONx_SYNCI) bit is set high when a
change occures in the monitor’s synchronization status. Whenever a state machine of the x
STS-1 path goes from Synchronized to Out Of Synchronization state or vice-versa, the
MONx_SYNCI is set high. This bit is independent of MONx_SYNCE, and is cleared after it’s
been read.
