Re: OPTI-3 error message

MAN alarm is an Alert that the Working OC3 and/or Protect OC3 is in an Out of Service, Maintenance State, to clear that alarm you would just put the OC3 In Service.

Out Of Service, Maintenance is a Service state used to allow Loopbacks, and inhibit Critical or Major Alarms. Payload Data will still pass when in that state.
