What is hcxOc3HardwareVersion?

This read-only 16-character DisplayString reports the hardware revision of the OC-3 card, returning an empty string if no card is currently inserted in the slot. It lets an administrator verify OC-3 card hardware compatibility before a firmware push, with the empty-string behavior doubling as a presence check. For example, an operator polling this field and getting an empty string back would know the OC-3 slot is physically empty rather than assume the card has crashed.
