Alarm Analysis for HOP

LOM (Loss Of Multiframe): A LOM is declared when a OOM1 or
OOM2 is present while the whole H4 is not recovered within 48
STS-1/STS-3c or VC-3/VC-4 frames. The LOM state is cleared when
both multiframe alignment processes are in the in-multiframe state
IM1 (Stage 1) and IM2 (Stage 2).
OOM1 (Out-Of-Multiframe of stage 1): A OOM1 is declared when
an error is detected in the MFI1 sequence. The OOM1 state is
cleared when error-free MFI1 sequences are found in four
consecutive STS-1/STS-3c or VC-3/VC-4 frames, then a IM1 state is
declared.
OOM2 (Out-Of-Multiframe of stage 2): A OOM2 is declared when
an error is detected in the MFI2 sequence or the first multiframe
stage is in the OOM1 state. The OOM2 state is cleared when IM1
state is declared while error-free MFI2 sequences are found in two
consecutive first-stage multiframes, then a IM2 state is declared.
