Is it possible to use a UTP cable for:
- 12V DC (~30W),
- 100BASE-TX Ethernet, and
- A single phone line,
at the same time? 100BASE-TX should give me two spare pairs, can I use one pair for the phone line and one for the power?
My plan is to supply a (rather old) VoIP-capable board with power, internet and a hook it up to a single phone. Can I do all that with a single cable? If yes, how do I do the wiring (
i.e. which are the spare pairs in 100BASE-TX Nevermind. Found that on Wikipedia)?
To clarify, I would only run this over a short distance, 1-2m.
