Product Information

The conductors other than the two central tip and ring conductors are in practice variously used for a second or third telephone line, a ground for selective ringers, low-voltage power for a dial light, or for anti-tinkle circuitry to prevent pulse dialing phones from sounding the bell on other extensions.

Archived from the original on 2014-06-26. Rj9 is used majorly in connecting landlines to handsets, whereas rj22 can connect landlines as well as other communication networking devices to one another. The Rj9 connector type has less versatility in connection as it only comes with one type of connector, which is 4P4C. At the same time, Rj11 provides more versatility in connecting devices due to its two configuration types, 6P2C and 6P4C.

However, it is more modest than the Rj11. It is made with plastic and is additionally understood, permitting you to see the association of wires inside. A router-to-router crossover cable uses two 8-position connectors and a unshielded twisted pair (UTP) cable with differently wired connectors at each end.

RJ45 is an 8P8C wiring standard. This means that there are also 8 wires that are terminated in the connector, occupying all the available slots.

Rj9 Cables

In analog mobile telephony, the 8P8C connector was used to connect an AMPS cellular handset to its (separate) base unit; this usage is now obsolete. The Rj9 has a different shape than the Rj11. It is rectangular, while the Rj11 is a square-shaped connector. Motorola uses the 10-pin connector as a microphone connector in several of their mobile radio product lines. [ citation needed] It is made utilizing plastic that is solid and very firm. It is tiny and tips the scales at 0.16 ounces.

The micro ribbon connector, first made by Amphenol, that is used in the RJ21 interface, has also been used to connect Ethernet ports in bulk from a switch with 50-pin ports to a Cat-5 rated patch panel, or between two patch panels. A cable with a 50-pin connector on one end can support six fully wired 8P8C connectors or Ethernet ports on a patch panel with one spare pair. Alternatively, only the necessary pairs for 10/100 Ethernet can be wired allowing twelve Ethernet ports with a single spare pair. RJ11 uses a standard 6P2C connector for a standard telephone connection. It only uses a 6P4C connector when low voltage power is required to send to the indicator lamp of the telephone.

Established in the 1950s for polyethylene-insulated conductor (PIC) cable. Horn, F. W. (October 1958). " 'Even-Count' Cable" (PDF). Bell Laboratories Record. 37 (5): 208–217 . Retrieved October 13, 2022. Modular connectors are often used for data links, such as serial line connections, because of their compact dimensions. For example, some DirecTV set-top boxes include a 4P4C data port connector with an adapter cord to a computer serial port so that remote control is possible from the computer.

IEC 60603-7-1: Connectors for electronic equipment: Part 7-1: Detail specification for 8-way, shielded free and fixed connectors with common mating features, with assessed quality This wiring provides a series tip and ring connection of a KTS line ahead of the line circuit because the registered equipment requires CO/PBX ringing and a bridged connection of the A and A1 lead from behind the line circuit. Tip and ring are the only leads opened when the CPE plug is inserted. Typical usage is for customer-provided automatic dialers and call restrictors. a b Krumreich C.L., Mosing L.W., The Evolution of a Telephone, Bell Laboratories Record 44(1) p.14 (January 1966)

The 4P4C arrangement of the Rj9 connector makes it ideal for associating phone handset links. It has 3 prongs in its wrinkles that make it viable with strong and abandoned wires. Whereas, The Rj11 connector is ideal for telephone lines and modem associations. The explanation is that it can simultaneously deal with a limit of 4 wires. edit ] 4P4C modular connector on a handset cord. Wired telephone that uses 4P4C connectors for the coiled handset cord. A conventional enumeration of wire color pairs then begins blue (and white), orange (and white), green (and white) and brown (and white), which subsumes a color-coding convention used in cables of 4 or fewer pairs (8 wires or less) with 8P and 6P connectors. line series connection using 50-pin connector (with bridging adapter) ahead of customer equipment. Mostly used for call sequencer equipment. This wiring pattern is for multi-line analog telephone use only; RJ61 is unsuitable for use with high-speed data because the pins for pairs 3 and 4 are too widely spaced for high signaling frequencies. T1 lines use another wiring for the same connector, designated RJ48. Ethernet over twisted pair ( 10BASE-T, 100BASE-TX and 1000BASE-T) also uses different wiring for the same connector, either T568A or T568B. RJ48, T568A, and T568B are all designed to keep both wires of each pair close together.pin RJ50 (10P10C) male (connector diagram and applications), Pinouts guide, archived from the original on 2013-05-18 , retrieved 2010-10-17 Due to the rectangular shape of Rj9, it is relatively minor in size. On the other hand, Rj11, the square-shaped connector, is comparably larger than Rj9.
