What I'm trying to do with that is apply a concept that is singularly appropriate or especially robust (even brain dead).
This "out of band" concept is early (1700s) and fundamental enough to be a linguistic concept - it is my favorite parse.
Is it is is it not "Out Of Band"
Not to separate "out of band" from in band information leads to confusion.
Ex. in security work the lock & key are "out of band" and the traffic or content is the process, that is the container that has a hasp lock on the front.
Networks transmit serial information (although I'm sure extra lines for control data never hurt anyone, as on the system bus or a back-plane.)
So with serial transmission the "out of band" information could be confused with the traffic/message itself.

Does that explain anything?
