What Is a Telephone Connector?
Telephone connectors are physical interfaces connecting telephones and related equipment to the telephone network.
Types include RJ11, RJ14, and RJ25. RJ11, a 6-position 4-contact (6P4C) connector, is used for single-line analog telephones in homes and small offices. RJ14, also 6P4C, supports two lines with different wiring configurations.
For digital communication, RJ45 connectors, which are 8-position 8-contact (8P8C), are utilized for Ethernet connections and data communication.
