Wiring Telephone Extensions via Patch Panel 1

[Mav3000]

Hi, I've just moved into a house and am looking to install twin network points in all the rooms - both using Cat5e.

I'd like one to be a network socket, and one to be a telephone socket (to accommodate Sky Digiboxes if needs be in the future), but want the choice of swapping them to network sockets where needed - so have decided to run the cables to a central patch panel. The Network Sockets can then go into the ADSL Router and the telepone sockets to the telephone.

I've read multiple articles online about this but am confused in regards to the telephone points.

How do you wire up the patch panel to allow each port to be a 'telephone port'?

Do you plug the phone line into the back of the patch panel, then daisy-chain the other sockets to it? this sounds very fiddly. I can't find a clear explaination of how this is done.

Any help would be appreciated.

Daisy chaining is the only way to make the analog telephone circuit appear at multiple locations.

I suggest terminating each wall jack seperately as you describe to allow for flexibility in the future. Then I would take the source circuit from your telco and daisy chain it to unused ports on the patch panel (on the back!). Make sure you daisy chain the same amount of these telco ports as you have wall jacks to activate for phones. Then use a patch cable between a telco jack and a wall jack.

I hope this makes sense. I think this would be your cleanest option.

Ok by the fact you are mentioning Sky you are UK based.

Set up the entire cabling as a standard, no need for BT sockets.

Then, things like ADSL's and even some phones that have RJ-11 plugs (little square one's) will plug straight into RJ-45.

Then for your BT style plugs you will need a RJ-45 to BT balland. And vice versa, to get BT socket into your patch panel (in fact BT-RJ11 are easier to find)

You will need SECONDARY ballands, as your BT sockets tend to be Mastered. How do you tell?
If you take the face plate off, if there is a capacitor in there, it is a Master. This is required to make the phone ring!

look here for your ballands:

and get some RJ-11 cables.

Thanks Guys,

I plan to fit each wall socket in each room with twin RJ45 sockets, to allow the ports to be either telephone (with RJ45 adaptors) or ethernet network sockets.

I'm also toying with one patch panel for the telephone sockets and one for the network sockets to keep them seperated, and patching between them where a telephone point is needed.

My only real query (without ever seeing the back of a patch panel) is the thought of wiring the telephone wires from each patch panel point to the adjoining one - as this sounds very fiddly and messy around the back of it.

The wiring plan is:

1) Filter Telephone Line at BT Master Socket NTE5 using ADSL Adaptor

2) Take ADSL Feed to Router

3) Take Router to 4 Network Terminals on Patch Panel Ports 1-4

4) Take Filtered Telephone Line to Patch Panel Port 5.

5) Daisy-chain wiring from port 5, to port 6, 7 and then 8 to give up to 4 telephone extension sockets.

6) Wire House (eek!)

7) Connect Sockets to patch panel as needed.


One final question - if I have to manually wire in the wires for the telephone extensions (presumably using ICT terminals), so I have to manually wire in the 4 wires from the Router?

If I get a Patch Panel that accepts RJ45 in the back of it, can I also somehow plug the incoming telephone wires into the back using RJ45? How?

Thanks for the advice. As mentioned, I've not seen these questions answered online.

What's a balland, I've heard of Baluns, which stands for balanced/unbalanced?

OK, here's another idea.

You can buy a 100-pair 110 block that is wired out to 12 RJ45 sockets. Plop that on the wall close to your patch panel, take the wire for the phone line you want to use (or phone lines as it may be) and punch it down (daisy chain) on all of the blue colored punch down connectors (if you are using "residential" phone wire that is green, red, yellow and black, the green comes first and then the red). If you have 2 phone lines you have the choice of punching the 2nd phone line down to all the orange connectors and having it available at each phone lack (using an L1 + L2 splitter) or you can punch line 1 on some jacks and line 2 on others as you see fit.

Then it is a simple matter of taking a short phone cord and plugging in the RJ45 ports on your 110 block that is hooked up to your phone lines to whichever locations you want them to go on the patch panel.

This also keeps the patch panel "pure" and up to CAT5 standards so you can always use any port for any purpose.

The more I read the more I think keeping the Cat5 and the Telephone Lines in seperate Patch Panels makes sense. I'll look into the 110 block you mention and see if this will help me. Thanks for your help everyone!

I wire offices with nothing but Cat5/Cat6 when I can talk the customer into it (not too hard as the only real difference is the additional patch panel) then set up a voice patch panel at the same location. as noted above the RJ-11 will connect into the RJ-45 jack. all of the voice appearances (stations for phone system or multiple locations for Plain Telephone service) are created on the voice panel and then connected to the RJ-45 panel with RJ-11 patch cords end result is flexibility for the customer, Need two phones at this desk? just change the patch for it. need the fax and one phone? Just patch it. show the customer how to make the changes and the customer is a lot happier than having to have a tech come out for simple office swaps.

Note with the additional equipment you noted above "Balland" etc you might be able to make that connection on the voice patch panel and just patch it to the location. I am not familiar with the equipment but so far with voice you can useually get away with having the equipment in the phone room.

If you are running all Cat5e cable, one jack per cable, how do you accomplish multiple phones at one desk, or a phone and a fax? How many runs of cable do you install at each location? With 66 blocks, cat 3 cable, and 6 pin jacks it is easy, I can have four devices per cable. While you can do that with Cat5e, splitting it out defeats the purpose...

From one RJ45 drop you can install an L1/L2 splitter or an L1/L2/L3 splitter to break out the lines. If you use a 6-wire Rj11/Rj12 for your cross-connect (or punch a phone line on the blue, orange and green pairs) you can easily get your 3 phone lines from 1 jack.

 

[jerryreeve]

I do two or three cables per drop, for office it is easiest. for a house location a L1/L2 splitter on both ends is almost perfect (just a little too wide for side by side on a patch panel.)

Hi All,

It's been a while since I started this thread, but now I have moved into the house and settle in, and have ordered the Cat5e cable for this job to commmence.

I plan to take a filtered lead from my BT NTE5 socket (sockets no.2 and no.5) and put this into a Voice Patch Panel, then daisy-chain this to 3 other sockets on the Patch Panel to give me 4 Voice extension sockets.

I also plan to take an unfiltered lead from the NTE5 socket to a Router, and then 4 leads from the Router to a Data Patch Panel.

I have one question however that is confusing me:

I wire the Voice wires from the NTE5 to the Patch Panel:

Socket No.2: Blue
Socket No.5: White/Blue

However on an RJ45 plug, the blue wires are in sockets No.4 and No.5.

How can this marry up if I swap a wall socket from being a Voice socket to a Data Socket? if the blue wires are in two different socket no.s?

I think I'm missing something here!

 

[Deweyhumbolt]

The blues are always in the middle (pins 4,5) on RJ11, RJ25, and RJ45. They are just reversed.

I think I understand what I need to do here.

The BT line comes in on socket number 2 (blue) and 5 (white/blue). To make an RJ45 socket work as either a data socket or a voice socket, I need to connect the voice patch panel cables into socket number 4 and 5:

BT | Voice Patch
2 - 4
5 - 5

I can also connect the bell wire from BT 3 to Voice Patch 2 if I want the phones to ring.

Please correct me if I'm wrong!

 

[donb01]

I may be speaking out of line here and I apologize if I am, but in the US, with the majority of the modern (Analog) phones, polarity is no longer all that important. On an RJ45 jack, pin 5 is typically Tip (white/blue) and pin 4 is typically Ring (blue/white), so the way you have it written appears correct. The thing you confuse me with is this reference to a 3rd wire. in the US there is no 3rd wire. The phones ring off the same 2 wires that connect to 4/5. That may be something different in the UK that I am not aware of.

 

[Mav3000]

In the UK we have on a typical phone socket connection pins 2 and 5 - these are usually Orange and White/Orange. There is however a third 'bell wire'. This doesn't come from the drop cable, but from the master socket. This is then taken to any extensions to make them ring (the master socket contains a ring capacitor).

However, it's been found that the bell wire is detrimental to broadband speeds here, so is generally not fitted to the extensions.

My query was about taking a UK BT phone socket (pins 2 and 5) and changing the socket type to RJ45. I've since learnt that these go onto pins 4 and 5, so should be ok to be patchable extension sockets for either data or phone.

 

[LkEErie]

It took awhile, but I think I finally understand the UK system. When you refer to pins 2 & 5, it would be our second pair. On a 6 pin jack with USOC wiring (RJ-25), 4&3 is the T&R, then 2&5 and 1&6 for pairs 2 and 3. In RJ-45, for USOC it's 54,36,27 and 18. For T-568-A it's 54,36,12,78 and B is 54,12,36,78.

In all cases, the 1st pair T&R is reversed.
