Xmultiple offers a complete product line of RJ11 connectors. An RJ11 jack is nearly always a 6P4C jack, with four wires running to a central junction box, but unused. The extra connectors used to be used as an 'anti-tinkle' circuit to prevent a pulse-dialing phone from ringing the bell on other extensions. With tone dialing this isn't required so the connectors are used to provide flexibility so the jack can be rewired later as RJ14 or to supply additional power for special uses. Similarly, the cables used to plug telephone terminals into RJ11 jacks frequently are four-wire cables with 6P4C plugs.

An RJ11 jack uses two of the six positions, so could be wired with a 6P2C (six position, two conductor) variety of modular jack, but such jacks are quite rare. Xmultiple offers RJ11 connectors in 6 positions with 2 connectors as well as 6 positionw with 4 contactors or 6 contacts.

In the powered variation, Pins 2 and 5 (black and yellow) carry 24-volt, DC power. While the phone line itself supplies enough power for most telephone terminals, old telephone terminals with incandescent lights in them (such as the classic Western Electric Trimline) need more power than the phone line can supply. Typically, the power on Pins 2 and 5 comes from a transformer plugged into a wall near one jack, supplying power to all of the jacks in the house.
