A standardized interface for connecting telephone equipment to a building’s wiring system, typically installed flush against a wall surface. These connection points allow for the easy and reliable connection of telephones, fax machines, and modems to the public switched telephone network (PSTN). An example includes the common RJ11 connector, used for single-line phone connections, secured within a housing that is fixed to the wall.
These fixtures offer a convenient and organized method for accessing telecommunications services. Their prevalence in residential and commercial buildings reflects their contribution to maintaining functional communication systems. Historically, these physical connections represented the primary method of establishing voice and data links, predating widespread adoption of wireless technologies. The secure and stable connection provided by such a fixture offers a reliable alternative when wireless networks are unavailable or unreliable.
