So try this

Install standard T568A/B jack on each end and pick one of these:

Or make your own?

In the late nineties, the late nineties, I was called on to add satellite to a new spec home that had been built into the side of a hill.

The driveway led up to the garage; stairs led up to three stories above that. The garage was at one end of the house. The idiot who designed the house cabling had run three RG-59 (in the late nineties!), one to each floor; on each floor, each cable daisy-chained through two-way splitters so that the signal at the far end was 12 dB lower than at the garage end of the house.

I changed the design so the cable signal was boosted like 20 dB before it went up to the floors, and then drop taps dropped signal across each floor.

But they wanted satellite, too. I was able to diplex satellite to the end of the house closest to the garage, but that was it.

Idiots.

LOL.
There was a custom home builder in the Fallbrook California area that did the same thing (or at least his electrician did).
Even odder, the RG-59 used had "WALMART LOSS PREVENTION" printed on it. I chuckled at the irony.
These were sold as "smart house" wired homes, all in the $1,000,000-$5,000,000 range.

Homeowners were none to happy when I told them I couldn't install Directv. No cable in the area either (rural).

I would use the brown pair unless it is in a mission critical area (office, av rack). I don't see use of gigabit in the kitchen anytime soon.
I am a trained professional..... Do not attempt this stunt at home.

I like that - standard wiring inside the wall - and a clearly marked device that shows what is what.

Good find. Thanks!

So basically instead of punching down the brown pair into the cat5 jack, run these up to the telco jack, eh?

Heap, as others already stated, 10/100 networks do NOT use pins 4,5,7,8, including standard PoE

pins 1,2,3, and 6 on an rj45 are used for 10/100 networks.

so if you use the orange and green pairs for 1,2,3, and 6, that will leave the blue and brown pairs for telephone lines.

There's nothing sacred about any colors of CAT5 wires. I choose to use blue and orange for phone a) in case two pairs are needed, b) those are standard phone wire colors, and c) since the data connection is not being done the ordinary way, there's no way its color code can be normal.

Or maybe it comes down to choosing to honor a two-pair data color code or a two-pair phone color code.
A good answer is easier with a clear question giving the make and model of everything.

Sure there is; it's called standards, as in TIA/EIA-568A or TIA/EIA-568B

To further clarify, whether you use A or B standard for Ethernet 10/100, you'll still have blue and brown pairs unused.

We have done some really crazy things in tough retrofits, using a single cat-5 to carry data in two pairs, a composite signal for a camera in one pair and IR in the last pair. Several other things worked. Even coaxial over twisted pair. 10/100 network over a telephone cat-3 cable.
Speakers using cat-5, telephone using coax. All you can imagine.
Trust me, i've made several customers happy by improvising in situations where there was no other way around.

I prefer a wired workaround over any wireless or "over powerline" solution.

Mario,
there's "something sacred" about RG6 versus RG59, by which I mean they do not perform the same way. These are inherent differences.

When I say there's nothing sacred about the wire colors of a CAT cable, I mean there is nothing inherent in the different colored pairs. They will all function the same, within a range of functions. IT's a range due to different pair twisting rates, which are not predictable or determined by wire color except for each particular model -- and even that is not a spec, it's just a manufacturing habit to meet the actual spec of "different" by some defined performance spec.

You know the word "nominal"? It comes from the same root as "noun" and "name." It means "it's what we call it." The wire colors are nominally different because 568A and B spell out, for the sake of conformity and for the next guy coming along to work on the system, which color goes where. There's nothing sacred about the wire colors. It's just handy to always do them the same.

Always having blue and brown is no big whoop, as blue and orange are the first two pairs of telephone multipair cable color code. So you have to decide whether you want to use a color coding that matches two pairs of data or two pairs of phone. You can't do both.

I stick with TIA/EIA-568A or TIA/EIA-568B standards so that if someone uses blue pair for phone, it doesn't screw up the network switch.
