RJ-11, RJ-45
Registered Jacks (sometimes described as RJ-XX), a series of telephone
connection interfaces (receptacle and plug) that are registered with the U.S.
Federal Communications Commission (FCC). The most common telephone
jack is the RJ-11 jack, which can have six conductors but is usually
implemented with four. The RJ-11 jack is likely to be the jack that your
household or office phones are plugged into from the ordinary “untwisted”
wire (sometimes called “gray satin” or “flat wire”) that people are most
familiar with. The RJ-45 is a single-line jack for digital transmission over
ordinary phone wire, either untwisted or twisted; the interface has eight pins
or positions.
