squelched.
3.10.8.8.1 — HSB Switching Criteria
The switching criteria are:
• MPT Access Card Fail status
• IDU-ODU Connection Failure
• ICP alarm
• Incompatible Shifter alarm
• Incompatible Frequency alarm
• Incompatible Power alarm
• Incompatible Modulation Parameters alarm
• Mated MPT Access card Failure
• Inter-MPT coupling link failure. Where there is a cross configuration (EPS on Spare

inter-MPT coupling link failure.
