Which of the following types of connectors is used in Plain Old Telephone Service (POTS) connections?

Plain Old Telephone Service uses a simple two-wire copper pair, and the standard connector for that setup is RJ11. This modular plug is the familiar 6-position connector that most home telephones and wall jacks use; it typically carries just two active conductors for single-line voice service, which is exactly what POTS relies on. Other options exist for multi-line telephones (using more conductors) or for networking, but for the basic POTS connection, RJ11 is the standard choice. RJ45 is for Ethernet, and RJ14/RJ25 cater to multi-line configurations, not the common single-line POTS plug.
