B.K. Electric Services now installs and services all data and telephone cables and wiring. All of our electricians are trained to fix a wide selection of jacks, for both home and business. We have ample experience fixing all registered jacks in use today. Registered jacks are several standard designs used to connect data equipment to a telephone company. These jacks include the RJ11, by far the most common, the RJ14, RJ21, RJ45, and the RJ48.

North America currently uses the RJ11 and its variants. The RJ11 is a modular connector wired for the basic form of telephone service most homes and business have today. Most phones today are meant to plug into RJ11, RJ14, or RJ25 jacks; the type depends on how many lines the phone has.
