JXM2119 didn't tell us what kind signal s/he's using. I inferred Ethernet from the context of the question; if s/he has some other signal in mind, perhaps s/he should let us know.
I agree that 8-position modular connectors can be wired for things other than Ethernet; that's why my response to the original question began with the word "if." But I don't agree with the use of the term "RJ-45" to identify a connector. RJ45 is a USOC (albeit apparently obsolete); not a connector.
