Registration interfaces were first defined in the Universal Service Ordering Code USOC system of the Bell System in the United States for complying with the registration program for customer supplied telephone equipment mandated by the Federal Communications Commission FCC in the 1. They were subsequently codified in title 4. Lucky Seven Sp Eng Sub. Code of Federal Regulations Part 6. The specification includes physical construction, wiring, and signal semantics. Accordingly, registered jacks are primarily named by the letters RJ, followed by two digits that express the type. Additionally, letter suffixes indicate minor variations. For example, RJ1. RJ1. 4, and RJ2. 5 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 5. For example, RJ1. P2. C, RJ1. 4 uses a six position four conductor 6. P4. C modular jack, while RJ2. Naming standardeditThe 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. The same six position plug and jack commonly used for telephone line connections may be used for RJ1. RJ1. 4 or even RJ2. The RJ1. 1 standard dictates a single wire pair connection, while RJ1. RJ2. 5 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 6. P 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 6. P2. C. RJ1. 1 uses a 6. P2. C connector. The connectors could be supplied with more pins, but if more pins are actually wired, the interface is not an RJ1. History and authorityeditRegistration interfaces were created by the Bell System under a 1. 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 customers property to the communication providers 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 System, following the Communications Act of 1. Telephones were generally hardwired, but may have been installed with Bell System connectors to permit portability. The legal case Hush A Phone v. United States 1. Federal Communications Commissions FCC Carterfone 1. Bell System to allow some interconnection, culminating in the development of registered interfaces using new types of miniature connectors. Registered jacks replaced the use of protective couplers provided exclusively by the telephone company. The new modular connectors were much smaller and cheaper to produce than the earlier, bulkier connectors that were used in the Bell System since the 1. The Bell System issued specifications for the modular connectors and their wiring as Universal Service Order Codes USOC, which were the only standards at the time. USOCs are commonly specified to the communications provider by large businesses for a variety of services. Because there are many standardized interface options available to the customer, the customer must specify the type of interface required by RJUSOC. For a multi line interface such as the RJ2. If there are multiple RJ2. When the U. S. telephone industry was opened to more competition in the 1. FCC and codified in the Code of Federal Regulations CFR, Title 4. CFR Part 6. 8, Subpart F,2 superseded by T1. TR5 1. 99. 9. 3In January 2. FCC delegated responsibility for standardizing connections to the telephone network to a new private industry organization, the Administrative Council for Terminal Attachments4 ACTA. The FCC removed Subpart F from the CFR and added Subpart G, which delegates the task to the ACTA. The ACTA generates its recommendations for terminal attachments from the standards published by the engineering committees of the Telecommunications Industry Association TIA. ACTA and TIA jointly published a standard called TIAEIA IS 9. Htc Hd2 T8585 Android Software here. CFR. The current version of that standard, called TIA 9. A,5 specifies the modular connectors at length, but not the wiring. Instead, TIA 9. 68 A5 incorporates a standard called T1. TR5 1. 99. 9, Network and Customer Installation Interface Connector Wiring Configuration Catalog,3 by reference to specify the wiring. With the publication of TIA 9. B,4 the connector descriptions have been moved to TIA 1. A. 4 Note that a registered jack name such as RJ1. Registered jack typesedit. P4. C crimp on style connector commonly used for RJ1. RJ1. 4The most widely implemented registered jack in telecommunications is the RJ1. This is a modular connector wired for one telephone line, using the center two contacts of six available positions, and is used for single line telephones in homes and offices in most countries. RJ1. 4 is similar to RJ1. RJ2. 5 has three lines. RJ6. 1 is a similar registered jack for four lines. The RJ4. 5S jack is rarely used, but the designation RJ4. P8.
