In your context, you are describing parallel or multiplexed control pathways that are valid for their intended purposes in a closed system. In my work, the same terms are used to describe intentional modulation vs unintentional interference to other broadcast services or multiplexed transport streams. I am not suggesting that my context has anything to do with the design of the control system in the device your are describing. However, for FCC purposes, these devices will likely be considered under the computing device classification for the FCC under Title 47, Part 15 of the Rules and Regs.

It's certainly not undefined technical jargon, it's term often used by Cisco themselves and they are certainly a key player in the networking industry. It's a term that's been in use since IT&T Telex days in the telephone industry (DTMF) and that predates myself (I worked on Telex well after it's prime when they were winding down TimeTran (TimeTran was not just a trademark of IT&T it was the name of a set of mostly TTL communications mainframes at 67 Broad St. in NYC) and working on ARX (was the software version that didn't require wire-wrap tools and 300MB 19-head hard drives bigger than end tables)).

My copy of Newton's Telecommunications Dictionary is not on my desk or I'd post that definition.
It's just a perspective issue in this case. I'm looking at it from a physical infrastructure stand point. You're looking at it from the permitted RF emissions stand point (which is fine but we're still working out the structure stand point). I'm not sure how many people reading this are licensed ham radio operators any more (which stinks but I sold off my rig years ago).
None the less, I fully intend to test this unit far more than I think FIRST will require. In the past I've been surprised by the shear amount of energy even my low voltage LED lighting can emit in the RF spectrum. It's part of the reason my LED lighting power supplies intentionally walk their base PWM frequency and cycle timing from module to module (12V and 10kW could make a mighty amount of RF interference).
