Post a Comment. Before we get into separating the phone lines, lets understand whats going on in the jack. Nobody uses the old quad green, red, black, yellow phone cable anymore in new wiring. Its mainly Cat3 or better cable which consists of 4 twisted pairs of wire in blue, orange, green and brown along with their white wire that has a colored stripe white-blue, white-orange, white-green, white-brown. Since a standard telephone only needs one pair of wires per line, we can send up to 4 lines on each cable.

This offers a lot of flexibility and saves time and labor running phone cables in a multi-line system. Even if youre only going to be running a single phone line, you have room for expansion. For consistency, the ability to utilize all 4 lines and to save space in the wall jack, phone installations are typically terminated in an 8P8C 8 pin 8 conductor jack.

This is the same jack used for your ethernet cable. This is a bigger jack than you might normally expect for a phone which is typically a smaller 6P6C or similar RJ11, RJ12, etc.

Only difference is the number of wires in the cable. There are three standard ways of wiring a phone jack. The difference is what colors are connected to what pins on the jack.

TA is the preferred method for wiring telephone and ethernet jacks and the only method suggested in the residential TIAB specification. Somehow TB became popular in U. To all the naysayers See sometimes the government can do things better than the private sector. It would make sense to wire ports following the USOC specification but by using TA a cable can later be easily switched from voice to data or vice versa in the future.

If you have a two line phone, you can plug it directly into a TA wired jack and both lines will work. Its not preferred since you might damage the other pins but it is designed to work that way. Unless you need to match a currently installed pinout plan, try to always use TA.

Either way, its important to know how your jacks are actually wired. Telephone Jack. Compare the above jacks with old style 2-line phone jacks that used to be used on walls and are still used in phones.

They look like this. The above is a standard 6P4C telephone jack that supports 2 phone line s.Read these instructions and become familar with the wiring diagrams before you begin your installation.

Wiring schemes are different for twisted and nontwisted wire. Wire pairings are critical for proper operation and vary depending on type of wire used. Understanding of all the wiring parameters is advisable before undertaking an installation. Flat ribbon cables, particularly those manufactured with RJ11 ends are not configured properly for use between etherSPLIT splitters flat ribbon cable will work fine for the phone connection ONLY from the phone jacks on the splitters.

Flat ribbon cable also will not conform to impedance matching requirements. While this type of cable may work for short distances, it will certainly fail on longer distances. Locate the hub splitter as near to the end-user wall plate splitter as possible.

It is also possible to use etherSPLIT to interconnect hubs using existing building wire if available. It is not advisable to use backbone cable or other wire to connect wiring closets with all of the hub splitters in one wiring closet. This may result in cable impedance mismatches that cause excessive reflections in the line resulting in high loss rates or inability to transfer data. Do not mix wire types. In cases where hub splitters MUST be congregated in one wiring closet, with interconnects to other wiring closets remember the ft maximum rule applies!

For instance, mixing straight, four conductor non-paired wire with category 3 twisted wire will NOT work. Use the same type of wire installed in the building for cross connects from the punch-down block to the etherSPLIT hub splitter. Keep runs under ft. Where distances between the tenant and the wiring closet exceed that distance, look for a junction box or riser access midway between that can be accessed.

It is usually possible to locate an enclosure box at some mid-point where hub and splitter equipment can be located. Planning A. Site Survey The first step in deploying etherSPLIT as part of a local area Internet access network is surveying the installation site for adequate access and wiring.

For successful implementation, suitable wire is required between the tenant unit and wiring closet or demarcation point.

For multi-line key or digital systems, or units requiring two analog phone lines, six wires or three twisted-pair are required.RJ is an acronym for Registered Jack. Registered Jack type 11 is standard for telephone use in North America and many other parts of the world.

There are registered jack designations from RJ11 to RJ Though the RJ connector has a total of 6 connector positions, typically either only 2 or 4 are used.

RJ connector wiring comes in two standard types. The RJ connector has six terminals on it. Typically, only the middle 4 are used.

Line 1 is the center pair, red and green. More recently Cat5 cable is being used. In that case, the blue pairs are for the first line and use the orange pairs for the second line. The punch down tool is an impact tool that pushes the wire into the metal receiver of the block and cuts off the excess wire. For a demarc is part of the Telephone System where the telephone company may use a Punch Down Block such as the 66 Block. Some installations pull a Cat.

Used on a punch down block to bridge the left side incoming connection to telephones or other telephony devices connected on the right side of the punch down block via wired to jacks. For a 66 block it is a good idea to have a service loop. Add an extra 2 feet and 2 inches for a service loop. The service loop is the extra wire you leave in the event that the punch down block needs rewired due to a problem with something like a broken wire. Without extra, it might be necessary for the entire drop to be replaced.

The service loop is used wrapped at the bottom of the punch down block. RJ is the standard for most telephones, answering machines and fax machines used in North America. Go about an inch or more in and strip the telephone wire. Now use the string inside with the wire pairs to pull back, cutting further into the wire, exposing more.

Cut off the wire right at where you applied the wire stripper. When you strip telephone or Ethernet wire the wire strippers often damage the small fragile wire.

It creates some waste, but it ensures you have no compromised wire. Now trim away the excess insulation which has been cut by pulling back the string and left hanging. Apply the blue and the blue white into the RJ block. It is good to keep a twist present right up to where the cable goes into the block.

The two center pins on the RJ11 will be used for a single line telephone. Jump to: navigationsearch. Categories : Computer Technology Networking Telephone.

Personal tools Create account Log in.In older telephone installations, the phone cable typically has four wires inside: red, green, black, and yellow. Category cable works just as well as the old cable for phone service, and it works much better for data such as for a DSL internet connection.

With either type of cable, once the cable is run to the jack location, wiring the jack is a simple matter of matching up the correct wire colors. In fact, only the phone company can shut off the power to the phone system. But just to be safe, don't work on phone wiring with wet hands or when standing in water. Rotate the strippers as needed to cut all the way around the sheathing, being careful not to cut into the insulated wires inside the cable.

Pull the cut piece of sheathing off of the end of the cable to expose the inner wires. Trim off the portion of cut sheathing, using the cutters on the strippers or using cutting pliers.

Untwist the individual wires inside the cable from one another. In many cases, you'll need to strip only two of the wires if you are installing a standard one-line residential phone line. A second pair of wires is used if you are installing a second line, such as a fax line or second voice-phone line.

Then, identify the individual wires you'll be using:. Old four-wire cable:. Cat-3 or cat-5 cable:. Remove the cover from the front of the phone jack, exposing the mounting plate and mounting screw holes. If the phone cable is run inside the wall, thread it through the opening in the plate as you position the plate against the wall over the access hole. If the phone cable is surface-mounted, such as to the front of a baseboard, the cable typically is inserted through a notch in the side of the phone jack.

Mount the plate to the wall, molding, or other structure, using a screwdriver and small wood screws or drywall screws. Some phone jacks may have self-adhesive strips for securing the plate to the wall, but if this type of jack also has screw openings, it is a good idea to reinforce the installation with screws.

Connect the stripped wires from the phone cable to the corresponding screw terminals on the jack, using the following color combinations each jack terminal is identified by the color of the wire that is preattached to it :. To make the wire connections, loosen each terminal screw with a screwdriver.

Tighten the screw to secure the wire. The wire insulation should just touch the screw terminal and there should be no excess bare wire extending out from the screw. Reinstall the cover on to the jack's mounting plate.From Xmultiple Management. Figure 1. Figure 1 is the wiring scheme for the plug side of an RJ connector.

Figure 2 is the wiring scheme for the plug side of an RJ connector in accordance with TB standards. The TB standard is the most commonly used. The wiring diagram is shown with the "hook clip" on the underside. The wall jack may be wired in a different sequence because the wires may be crossed inside the jack. This will insure compliance with Ethernet wiring standards. Figure 3.

For reference purposes only, Figure 3 details the wiring scheme according to TA standards.

RJ45 Breakout Cable for Multi-line Analog Phone System

Do not mix different wiring specifications within the same wiring installation. Crossover Cable. Some applications may require a crossover cable. The most common use of a crossover cable occurs in wiring together two Hubs.

Pins 1 and 3 are crossed over, and Pins 2 and 6 are crossed over. Is this answer helpful? Back to Search Knowledge Base. Back to Discussion Forum.

Back to Frequently Asked Question. Glossary of Terms. Crossover Cable Some applications may require a crossover cable.A multi-line analog phone RJ45 breakout cable can take a single RJ45 connection with multiple analog phone lines and break them into individual connections or take multiple phone lines and combine them into one RJ45 connection.

In this following scenario, we have two analog phone lines wired to two individual RJ45 female connectors in a network rack. The following guide will walk you through the creation of an RJ45 breakout cable designed to take the 2 analog phone lines and transmit both lines across a single RJ45 connection for a multi-line analog phone. Typically, patch cables will use the TB standard, but always verify the patch cable's color code.

RJ45 connectors are primarily used for network cables and contain 8 contact points. These connections are often refereed to as 8P8C 8 Position 8 Contact. For this project, we will be using RJ45 connectors to collect analog phone lines that only use 2 contacts.

RJ11 cables will have 6 positions, but only use up to 4 conductors 6P4C. This type of cable can handle two different analog phone lines simulations. An RJ11 cable with 2 conductors 6P2C can only handle a single analog phone line. When an RJ11 cable is plugged into a female RJ45 connector, the center pins will line up. The above diagram shows which pins will connect between an RJ11 cable and an RJ45 connector.

The above wiring diagram shows which lines from the Cat5e patch cable will be used for each phone line. The patch panel was wired so that a phone can be plugged directly into the patch panel. We will make a patch cable that allows a 2-line analog phone to be plugged directly into a single RJ45 connector in an office and be patched to the correct phone lines.

Under most circumstances, the analog phone lines in a network patch panel will be wired as shown in this guide. However, always verify what standards and configurations were used during installation. Start by clipping the head off of the Cat5e patch cable and stripping off the outer jacket, as shown above. Strip the patch cable enough to allow each pair to reach their designated spot on the patch panel.

The image above shows the patch cable stripped to 2".

Did you make this project? Share it with us! I Made It! Half Square Triangles Kinetic Art by andrei.A lot of people shy away from home telephone wiring. They may think that they are not allowed to touch the existing ones.

This is not so. Your local phone company will come and do your wiring for you, but it will cost you. Wiring a jack is not difficult and it is totally fine to add a new jack or internet phone jack to your system. You should disconnect the main phone line from the source before continuing wiring a phone jack.

How To Make RJ45 Network Patch Cables - Cat 5E and Cat 6

The phone line usually comes in by your electrical panel. There will be a small box with a phone line going in and coming out. This is called your "Connecting Block". Carefully remove the cover and disconnect the wires noting where you removed them from. When wiring a phone jack, you will notice that the wires are different colors. Here is a chart that defines the colors:. These instructions assume that you have already run the home telephone wiring to the new location.

All you need to get started is a screwdriver, a pair of needle nose pliers and a wire stripper. Make a small "hook" in the wire with the needle nose pliers and place the wire under the screw. Make sure the wire is wrapped around the screw in a clockwise direction so it will stay under the screw when you tighten it.

Now that you have your phone jack wiring complete, you must now hook the telephone wire up to the connecting block. Again, depending on the age of you home, the conecting block could be as simple as two screws. A red and a green. If you have a newer connecting box I beleive they are called R66 Connecting Block or a 2 Pair Connecting Block just find an empty pair of screws and connect the wires in.

Additional lines would be need for a fax machine or second phone line naturally. Now you have the home telephone wiring you have always desired.
