RJ45 CAT5eUTP Sockets: Choosing 568A or 568B Wiring for Universal Home Network Setup

Hello,

In the newly built house, I have cables for the Internet / telephone - 4-pair twisted pair. A socket is provided in each room and I am currently at the stage of installing sockets in the walls - RJ45 CAT5eUTP sockets. I have not yet specified where and how routers, computers, etc. will be connected.

I have to install the sockets now and therefore I would like to ask specialists how to connect them. In the 568A or 568B system? Will one of these solutions be more universal than the other? Or maybe it is necessary to know the layout of devices (routers, computers) already at this stage?

Of course, I can disassemble the sockets later and replace the cables, but I prefer to avoid it.

Please do not refer me to the links with the description of the difference between 568A and B and to the topics of straight and cross cables. I know these basics.

Best regards,
Gregory

It does not matter - you only have to apply the same on the other hand.

I will add that the cables are distributed in a star pattern - they all diverge from one place - the box. However, I do not know if there will be a wifi router only, maybe it will not be enough and I will need separate wifi routers for the first and second floor. Perhaps I will only use the cable connection on the floors. Therefore, I do not know the exact location of the devices.

Stick to one pattern in the sockets as well as in the main point where you will have your router / switch.

Thanks very much to both gentlemen for their quick help :)

Can such a network also distribute a telephone (on one of the free pairs)? Will it not interfere if I "let" him go all over the building?

If you do not think about the 1Gbps transmission, of course you can (blue or brown pair) a bit inconsistent with the art, but you do this

But why such a step back? Who is it today laying the cables "on the phone"?

I am not building a house, but I am faced with the renovation of the apartment and I was thinking what to do and how to do it.
With such investments, you have to think a little ahead.

My conclusions

1. Minimum Cat6 cables, preferably with a cover (some sftp) - 1GB is a standard today, in a few years there will be 10GB cards, who knows?

2. Why any cables for the phone? -> a double RJ45 socket for each room
that is, 2 (say two !!!) cables must go to each room. In a few years, you'll agree Unless you later arrange a router in every room, and why, how cheaper is it to put a double cable, and in the "box" it is best to install a patch panel for 24 cables.

3.Each network cable = telephone defacto, for pennies you can order to make / or yourself an adapter with rj45 plug socket rj 11 phone

4. Telephones are set up with DECT (they cost less and less), 6 handsets can be submitted to a good-class combine.

5. If you want to go crazy with telephones in every room, you can buy a gate of 50-60 PLN with the possibility of connecting 2 phones via cable, the gate is of course connected with the RJ45 network cable.

6. In a few years there will be only VOIP telephones, telephone cables + sockets will remain in the walls - and you will not be able to stick anything there. In half a year you will order a round neon and cables to the dog's rooms for the doghouse.




Telephone cables are a thing of the past, in the era when every smartphone is practically a landline phone, and headphones cost pennies, it is a waste of strength and resources.

-> my 3 cents

Here, the author of the topic has cables already laid.

I agree here, but if someone wants, why not.

This can be done even without adapters ;)

I think that the proposal will work better in small companies or offices, but you can ...

Also my 3 cents ...

And that would be interesting to me how? I'm not talking about a sculpture like a wall cable + a crimped rj 11 plug.

as you apply the same socket standard (A or B) to all sockets is:
You "cross" the switchboard into the socket in the "cabinet" by plugging the telephone cable with the RJ9 terminal into the RJ45 socket, and then, on the other side, plug the small RJtek into the socket "centrally".

the disadvantage of this solution is that the phone blocks the entire cable.

Other workarounds are the modification of the plugs - that is, the cable from the computer and attached to the phone.

btw, there is another way: you connect VoIP phones between the computer and the network socket (unlike modems long ago) because they use Ethernet, you only need to configure them / or set up an asterisk server.

Simple: into the RJ45 (socket) hole you insert the RJ11 (telephone plug) if you use the middle pair. Some installers are intolerant of RJ11 in an RJ45 socket, but that's their business. The second option is to crimp the RJ45 so that the pair falls on the connected one (e.g. 4/5 or 7/8)

VooVoo
It seems to me that someone did it in such a way that it would be possible. That is, this unilateral RJ 45 and 11 compatibility is presumed. If it were otherwise, it would not be possible because someone would take care of it.

It is a pity that you do not have two cables per room as it was suggested because then you can even place the router where it suits you.

I propose to give up broadcasting the telephone signal with the same cable.
They did so for one of my clients and every storm was raining the router or computer.
It was only after 3 failures that I came with the tester and pulser.
The whole house squealed as I connected the pulser.
The client switched to WIFI so as not to burn network cards.

Playing the twisted-pair cable at the same time is a mediocre idea. Especially if Teflon comes from the outside and not VOIP nap.
But when it comes to using a twisted link point point to send Teflon and only the phone, I do not see any contraindications even by plugging in rj11 in rj45
Imagine you have office space rented to different clients and tenants change. And the installation as it is, if all sockets are enough and there are enough of them to terminate a crospanel somewhere in the basement, for example, there is no problem because you can connect at the bottom as you want and as needed.
The example is to show flexibility. Unfortunately, networks should be done at home as they are done in companies, and especially not the other way around.
As of today, however, the best solution for telephony at home fell in this thread, however, it is the mother and a few registered handsets.

I know it perfectly well. I wrote this on purpose because I had a discussion with one individual who claimed that rj11 must not be put in rj45. Maybe he is also looking in here?

Exactly, sure, I suggested a bit, I instinctively thought about Fritz, there you have to rework in some models. For example, on Livebox, it would be so without pain, Livebox Rj11-> Rj45 socket ---- Rj45 socket -> Rj11 cable.

The Germans with Fritzboxes also do so that you get a telephone cable on Rj45 with only 2 middle ones for the telephone.

So I contradict the thesis that you cannot put rj11 into rj45

Welcome back,


Many thanks for a lot of answers and hints. Some are a bit of black magic so far Unfortunately, it is impossible to let go of the double cables now - too late - I gave the bodies :(

Are there now telephone exchanges that also support intercom / bolt release and can have (daughters) telephones working without a cable? I am interested in cheaper solutions, the phone would most likely be from Neti.

I put the cable mainly under the telephone exchange, and the internet was supposed to be WiFi, unfortunately it turned out that it cannot be done with one router - walls and ceilings probably too thick I would like to add that the house will be half an office, which is why I combine it this way.

Best regards,
Gregory

Hmm, I would consider ripping the walls halfway down the house, seriously!
As with a friend, the builders put a twisted pair from socket to socket in the bus topology, although it would be possible to pull it out of the walls and where possible, the cables were stretched under the board. I have already encountered a power cord that is located like electricity "from socket to socket" several times, and it is the work of electricians most often

As for one router and wifi, no problem, you can always arrange several of them. NP instead of switches, where you need to put a router with wifi as an accespoint, a bit of guerrilla that will take revenge, but if you don't like what you like ...

There are switchboards with intercom modules, but if you connect one mother to the switchboard, for example, with 5 headphones, you lose many of the advantages of the switchboard, switching calls, internal calls, etc.

Gentlemen, please do not propose to put the rj11 into the rj45 socket. So what if it fits, if in the long run the socket in the wall is damaged. It is not always possible to bend pins 1 and 8 into the correct position later. Replacing the socket is more troublesome than getting a RJ45 cable at one end.

@gieroj
If you have one cable to the room and you want to run the analog telephone and the network at the same time, be very careful about what and where is connected. Telephones beautifully unleash network devices. That is why I advise against connecting pairs for telephones in all cables.

Instead of playing the phone over the cable, immediately take an interest in DECT headphones. In my company Panasonic for PLN 120 allows you to talk calmly within 3 floors in a reinforced concrete office building.
Several new Siemens Gigasets have a separate base from the docking station at once, so if you would like to have several full-fledged handsets, you place the bases at the distribution point and the chargers in the rooms.
