Rj11 wiring color code

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.Return to Telephone Troubleshooting articles. In a typical home, the telephone cables connecting your phones within you home contain four wires They are used in pairs for each phone line you have.

Repairmen in fact refer to the wires in terms of "pairs", so technically a standard four wire telephone line has two pairs. LINE 1 uses the red-green pair.

This is especially true in some condominiums, where large bundles of wires servicing more than one customer may pass through your unit!

It makes sense, really. You can't have twenty wires serving ten units using four colors. I know there is a basement warehouse somewhere that contains volumes of secret government information about these wiring codes, undoubtedly next to the remains of space aliens in Roswell. You, however, don't need to crack the wiring code. You can determine the proper colors for your particular situation by simply observing what-goes-to-where.

So it's not really as complicated as it looks. Just follow the wiring conventions that are working, and you should have no problems!

Telephone wiring is color-coded Why your wiring colors don't match my colorsA registered jack RJ is a standardized telecommunication network interface for connecting voice and data equipment to a service provided by a local exchange carrier or long distance carrier.

Accordingly, registered jacks are primarily named by the letters RJfollowed by two digits that express the type. Additional letter suffixes indicate minor variations. For example, RJ11RJ14and RJ25 are the most commonly used interfaces for telephone connections for one- two- and three-line service, respectively.

Although these standards are legal definitions in the United States, some interfaces are used worldwide. The connectors used for registered jack installations are primarily the modular connector and the pin miniature ribbon connector. For example, RJ11 uses a six-position two-conductor connector 6P2CRJ14 uses a six-position four-conductor 6P4C modular jack, while RJ21 uses a pair pin miniature ribbon connector.

The registered jack designations originated in the standardization processes in the Bell System in the United States, and describe application circuits and not just the physical geometry of the connectors; inspection of the connector does not necessarily show which registered jack wiring is used.

The same modular connector type may be used for different registered jack applications. Strictly, Registered Jack refers to both the female physical connector modular connector and its wiring, but the term is often used loosely to refer to modular connectors regardless of wiring or gender, such as in Ethernet over twisted pair. There is much confusion over these connection standards.

Registered jack

The same six-position plug and jack commonly used for telephone line connections may be used for RJ11, RJ14 or even RJ25, all of which are names of interface standards that use this physical connector. The RJ11 standard dictates a single wire pair connection, while RJ14 is a configuration for two lines, and RJ25 uses all six wires for three telephones lines. The RJ designations, though, only pertain to the wiring of the jack, hence the name Registered Jack ; it is commonplace, but not strictly correct, to refer to an unwired plug by any of these names.

Modular connectors were developed to replace older telephone installation methods that used either hardwired cords, or bulkier varieties of telephone plugs. The common nomenclature for modular connectors includes the number of contact positions and the number of wires connected, for example 6P indicates a six-position modular plug or jack.

A six-position modular plug with conductors in the middle two positions and the other four positions unused has the designation 6P2C. RJ11 uses a 6P2C connector. The connectors could be supplied with more pins, but if more pins are actually wired, the interface is not an RJ Registration interfaces were created by the Bell System under a [ citation needed ] Federal Communications Commission order for the standard interconnection between telephone company equipment and customer premises equipment.

These interfaces used newly standardized jacks and plugs, primarily based on miniature modular connectors.

The wired communications provider telephone company is responsible for delivery of services to a minimum or main point of entry MPOE.

The MPOE is a utility box, usually containing surge protective circuitry, which connects the wiring on the customer's property to the communication provider's network. Customers are responsible for all jacks, wiring, and equipment on their side of the MPOE.

The intent was to establish a universal standard for wiring and interfaces, and to separate ownership of in-home or in-office telephone wiring from the wiring owned by the service provider. In the Bell Systemfollowing the Communications Act ofthe telephone companies owned all telecommunications equipment and they did not allow interconnection of third-party equipment. Telephones were generally hardwired, but may have been installed with Bell System connectors to permit portability.

A true RJ11 is a 6P2C jack. Registered Jack is a standardization created to describe the physical jack as well as its wiring and specifically refers to a jack but is loosely used in the industry to refer to modular plugs as well.

In when the Bell Company had a monopoly on the telephone industry, the phone company owned everything having to do with telephones. This means that Bell owned the cable, the cabling within the house and the phone itself; when they did this there was no way to connect anything to the phone line because the phones were hardwired directly to the network cable.

Because Bell owned everything there was no need to standardize cable connections for other companies to create their own products. Eventually between the efforts of two companies trying to establish their hold in the phone industry, the Carter Phone and Hush-a-Phonethe US government deemed that the Bell Company did indeed have an illegal monopoly and that regulations had to be set in place in.

Now the phone company only owns the cable that provides the service and because of that Bell had to come up with a universal standard for connecting the wide area network WAN with the local area networks LAN within each building. Tip and ring is a term still used today and can still be seen today but originated in the early days of telephony.

Back when phone networks started there was a human being operator instead of a machine. The operator would receive a call from someone within the network they were directly connected to then connect that call to a different network.

The operator had two plugs to connect the phone cable called the tip and the ring, much like how there are two connections on a modern day RJ11, the tip was the grounding cable and the ring carried the voltage. Today we have routers and switches that do the job of the original human operator. The 6 wires in a RJ11 connector are divided into 3 pairs: the first is striped blue and white, the second is orange and white, and the third pair is green and white.

The combination of these wires usually carries data or voice. A single-phone line uses only one pair of wires. A two-telephone line uses two pairs, and the third pair of wires could be used for a third line. Most dial-up computer modems are typically plugged into a RJ11 jack, whether for Internet connection or a local area network.

RJ11 jacks are typically used for fax, modem, and telephone. A RJ11 plug can also be plugged into a RJ45 jack.

It is the very small connectors used to connect your telephone to the handset. RJ As mentioned above, the most common telephone connector in the world is the RJ jack, which can have six conductors but usually is implemented with four or sometimes two.

The RJ jack is likely to be a socket that your household or office phones are plugged into. In turn, these sockets connect to the outside longer wires known as twisted pair, which run to the telephone companies switch or to a private branch exchange PABX. The four wires are usually characterised as a red and green pair and a black and white pair. The red and green pair typically carry voice or data.

On an outside phone company connection, the black and white pair may be used for Iow-voltage signals such as phone lights. On a PBX system, they may be used for other kinds of signalling.
