Alarm Generation
Note: Alarm generation is only available with multiplexed test case only.
OPU-MSIM (Multiplex Structure Identifier Mismatch): OPU-MSIM is an
OPU alarm that is available for multiplexed test case only. The
OPU-MSIM alarm is generated by corrupting the content of the PSI
(bytes 2 and 3 for ODU0 in ODU1, bytes 2 to 5 for ODU1 in ODU2, and
bytes 2 to 17 for ODU2 in ODU3).
Note: OPU-AIS and OPU-CSF are only available on the OPU client signal
(designated as LO in the standard). In this case, OPU-MSIM is not available.
OPU-AIS (OPU - Alarm Indication Signal): The OPU-AIS alarm is
generated by generating the PRBS 2^11-1 pattern.
OPU-CSF (OPU - Client Signal Fail): The OPU-CSF alarm is generated
by setting the bit 1 of the OPUk PSI[2] byte to "1".
On/Off button: The On/Off button is used to activate/deactivate the
selected alarm. This setting is disabled (Off) by default.
