RJ11 and RJ12 jacks are keystone jacks used as connectors in creating LANs in homes and offices, to set up phone networks, and so on. Given the many electronic devices such as computers that are data hungry, there is a need for these jacks to connect telecommunications ports to devices. Keystone jacks are essentially female type connectors that are mounted on a wall plate or patch panel.

Each of these keystone jacks are snap in packages that come in standardized sizes, making for ease of use. Each design and connector size and other specifications are meant for different applications. By using the right keystone jack you can easily connect various electronic and electrical devices. Two of these keystone jacks are called RJ11 and RJ12.
