Registered Jack

Registered Jacks are commonly used in the telecommunications industry. These jacks are standardized connectors used for connecting telecommunication equipment, such as telephones and modems, to a network. In the UK market, the most commonly used registered jack is the RJ11, which typically has four or six contacts and is used for connecting telephones and fax machines to a telephone line. Another common type is the RJ45, which has eight contacts and is used for connecting computers and other network devices to an Ethernet network. It is important to ensure that the correct type of registered jack is used for the specific application to ensure proper connectivity and functionality.
