What is hcxOc3UnitPrimServState?

This read-only PrimServiceState value reports the overall primary service state of the OC-3 card as a unit. It gives an administrator a quick top-level health check of the whole optical line card before drilling into individual port states. For example, an operator seeing this attribute report out-of-service would know the entire OC-3 card has a problem affecting all traffic riding the optical trunk.
