Telephone over CAT6

You shouldn't need an adapter, you can plug a phone into a network jack and it will work provided that the phone wires are active.

You want something like this for the phones. (here are some options) You connect it to the cable modem phone jack and then patch the phone jacks to it.

When will the people realize that with DRM they aren't purchasing anything?

The dimensions of the connectors are such that a plug can be inserted into a jack that has more positions than the plug, leaving the jack's outermost contacts unconnected. However, not all plugs from all manufacturers have this capability, and some jack manufacturers warn that their jacks are not designed to accept smaller plugs without damage. If an inserted plug lacks contact slots at the outermost extremes, it may permanently deform the outmost contacts of an incompatible jack.

Don't use adapters. Instead use RJ11 or RJ14 jacks for the telephone lines. Then it is very clear that that jack is not for Ethernet and is the one for the phone. What are you using the third home run to each room for?

reply to sr1nath
just have them put the proper jacks in the keystone plates, and in the basement tie them all together with the correct equipment. i just jumper all the patch ports together that will serve as telco, but then again the only times i used a patch panel for telco was at my own house. i prefer proper 66 blocks for telco since all mine are not designed for untrained personnel to make changes.

You can get wall plates and have rj45 and rj11 jacks installed. In my computer room i have a plate that has 2 rg6 coax cables 3 rj45 and a rj11 jack.

People still use landlines in their homes?

reply to sr1nath
The proper way to do things is to use the proper jacks on each end.
As whizkid mentioned, don't just cram an RJ11 or 14 into an RJ45. It will damage the pins and eventually get "wonky". RJ45 to RJ14 adapters are widely available and cheap, but it's nicer to just have the proper jack installed to begin with.

As others have mentioned only use RJ11 for the phone. My other concern is your wiring guy suggesting RJ45 for phone or going along with your initial plan to do so. Might want to check his references. Of course he may want the repair work later as I love getting these calls where I don't have to get my hands dirty.

RJ45 for phone when keystone jacks are DIRT-cheap? I'd like to toke what he's tokin' I ran a couple of DSL lines over CAT6 (got room for a couple more, not counting the 3 spare runs I've got going to that spot lol). straight from the terminals. Both were used for DSL, while I had it. On that plate I also had a couple of F-type connectors for cable Internet on a 4-port plate. Totally brainless work and very flexible.

True dat! Jack OD's are good money for not having to do much. I don't mind making a buck off of someone else' incompetence.

I wouldn't put two RG6 runs plus other cabling in a 4 port plate unless it was a low voltage bracket opening into the wall cavity. Gotta love the guys who rough everything into one box to save a couple bucks because they don't have to come back and do the terminations.

Wonder if something like this would work.

I've used Leviton quickport rj45 connectors on all wallplates in my house which works with rj45 and or rj11 for telephone.

I have something like this [»www.amazon.com/Leviton-47603-12P···152BSZS] in one of our rooms which distributes voice and data all over the house.

reply to sr1nath
Let your installer know that and they should get you the right jacks, we run rj45 here for everything and there is no need for adapters or anything. If you have a jack that is made to take either (we do use leviton) then you are set.

As far as the phone. Ask the installer if they would take specific runs and punch them down in parallel. From there plug the phone line from the modem in to that jack and you are done. You will have to have that jack repunched for anything else.

Phones are ran in parallel anyway, as long as you don't go over the Ring Equivalency Number rating for the modem you are fine.

Biggest issue of using RJ45 for phobnes is the possibility of plugging a computer to that jack. Ring signal to a NIC is not pretty.

reply to sr1nath
Use a different color jack for the phone lines. Of course, if you're doing that, use a phone-only jack to begin with.
