How to Wire a Phone Jack (Voice or Telephone RJ

How to Wire a Phone Jack (Voice or Telephone RJ-11 thru RJ-14) (USOC Wiring Diagram) Telephone wiring for a phone outlet is typically either 1, 2 or 3 pairs (2, 4, or 6 conductor). Most cable nowadays is UTP (unshielded twisted pair). There may be instances where you may need to connect to or transpose from the old "quad" cable.

Network Wiring Instructions for RJ11 and RJ45 RJ-11 (Telephone) Plug. Figure 1. Figure 1 is the wiring scheme for the plug side of an RJ-11 connector. The diagram is shown with the "hook clip" on the underside. The typical RJ-11 connector has six terminals.

Though the RJ-11 connector has a total of 6 connector positions, typically either only 2 or 4 are used. RJ-11 connector wiring comes in two standard types. There's (A) Untwisted and (B) Unshielded Twisted Pair. CAT5 connectors (RJ45) have 8 contacts (4 wire pairs); standard telephone jacks (RJ11) have 4 contacts (2 wire pairs).

The typical RJ-11 connector has six terminals. Usually, only the middle four pins are used. The POTS (Plain Old Telephone Service) residential telephone wiring generally contains two pairs of wires - designed for two separate telephone lines. The center pins (Red and Green) contain the first telephone line.

CAUTION: This post illustrates how to wire up a RJ-45 jack for use with a RJ-11 connector.Please be advised, that it is wise to use voice grade RJ-11 jacks instead of RJ-45 jacks for voice or telephone systems because you run the risk of someone plugging a computer into the phone jack, which might fry or ruin the network card in the computer if the telephone rings or is plugged into a phone ...

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.

6 pin RJ11, RJ14, RJ25 female connector at the phone and wallet socket (Jack). 6 pin RJ11, RJ14, RJ25 male connector at the cable (Plug). The six-position plug and jack commonly used for telephone line connections may be used for RJ11, RJ14 or even RJ25, all of which are actually names of interface standards that use this physical connector.

2. RJ11 and RJ12 only differs in the wiring 3. RJ12 utilizes all six slots while RJ11 only uses four of the six available slots 4. RJ11 and RJ12 are commonly used for telephone systems with RJ12 being used in different configurations 5. RJ11 is very common in today’s homes while RJ12 is quite uncommon except in some large companies

For example, telephone cables in the UK typically have a BS 6312 (UK standard) plug at the wall end and a 6P4C or 6P2C modular connector at the telephone end: this latter may be wired as per the RJ11 standard (with pins 3 and 4), or it may be wired with pins 2 and 5, as a straight through cable from the BT plug (which uses pins 2 and 5 for the line, unlike RJ11, which uses pins 3 and 4).
