Installing a telephone jack is a relatively simple task that can be completed in a few steps. A telephone jack is a type of electrical connector that is used to connect a telephone to a telephone line. Telephone jacks are typically installed in walls, but they can also be installed in other locations, such as on desks or in cabinets.
There are two main types of telephone jacks: RJ11 and RJ45. RJ11 jacks are the most common type of telephone jack, and they are used to connect standard telephones to a telephone line. RJ45 jacks are used to connect Ethernet devices, such as computers and routers, to a network.
