RJ48S is typically used for local-area data channels and subrate digital services and carries one line. It accepts a keyed variety of the 8P modular connector.

Retrieved 2009-09-10. 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.

ANSI/TIA-968-B documents of FCC specifications from the Administrative Council for Terminal Attachments, section 6.2 in particular Trulove 2005, p.219: User Cords and Connectors: This 8-pin modular plug is probably the most subject to name abuse, because it resembles the specialized RJ-45 connector. However, the RJ-45 wiring pattern (which includes an interface programming resistor) is so radically different from that of T568A and B that it really should not be called by that name at all. 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.

RJ61 is a physical interface that was often used for terminating twisted pair cables. It uses an eight-position, eight-conductor (8P8C) modular connector. 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. Due to the slight difference in the shape of Rj9, it is smaller than that of Rj11. The Rj9 has one connector type that is 4P4C, which means it contains 4 positions and 4 connection points, making it ideal for connecting telephone connections. With the advent of structured wiring systems and TIA/EIA-568 (now ANSI/TIA-568) conventions, the RJ61 wiring pattern is falling into disuse. The T568A and T568B standards are used in place of RJ61 so that a single wiring standard in a facility can be used for both voice and data.

This arrangement provides a series tip and ring connection to whatever line has been selected in a key telephone set plus a bridged A and A1 lead. RJ-45 Plug for Proposed CAT 6 Specifications" (PDF).

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. 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.

Unsourced material may be challenged and removed.In January 2001, the FCC delegated responsibility for standardizing connections to the telephone network to a new private industry organization, the Administrative Council for Terminal Attachments (ACTA). [4] For this delegation, the FCC removed Subpart F from the CFR and added Subpart G. The ACTA derives its recommendations for terminal attachments from the standards published by the engineering committees of the Telecommunications Industry Association (TIA). ACTA and TIA jointly published the standard TIA/EIA-IS-968, [6] replacing the CFR information. Motorola uses the 10-pin connector as a microphone connector in several of their mobile radio product lines. [ citation needed] 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. RJ11 is 4P4C wiring standard and 6P4C wiring standard which means it has 6 positions with 4 conductors.

Observing the male connector from the cable opening, with prong facing downward, the pins are numbered 1–6, left to right: The physical connector is standardized as the IEC 60603-7 8P8C modular connector with different categories of performance. The physical dimensions of the male and female connectors are specified in ANSI/TIA-1096-A and ISO-8877 standards and normally wired to the T568A and T568B pinouts specified in the ANSI/TIA-568 standard to be compatible with both telephone and Ethernet. RJ45 is often incorrectly used when referring to an 8P8C connector used for ANSI/TIA-568 T568A and T568B and Ethernet. It is distinct from the official RJ45S and ARJ45 interfaces.

RJ-11 is considered the basic connector for connecting a phone to the divider and the handset into the phone. RJ11 links can carry up to six wires for up to three phone lines, and their classification is RJ11, RJ14, or RJ25, depending upon the number of lines. Parameters of Comparison Mac Plus Keyboard Cable", Syrinx, UK: Megadon, ...the cable is the same as the telephone cable that connects handsets to the phone, unfortunately [...] this type of cable and pretty much any type of pre manufactured cable [...] is wired wrong for the Mac Plus. Under no circumstances should you use this cable as you will damage your keyboard and/or your Mac! 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. A variation of the standard, the CW1308B, has reinforced insulation for use both outdoors and indoors. This resists not only weather but also UV (ultraviolet) light.
