What Does Switched Line Mean?
A switched line is a communications link established through the use of switching equipment which allows a connection to be established between two transmission devices. The switched line provides a temporary connection between two user terminals or machines and only lasts for a certain period. Switched lines minimize the line costs while maintaining the advantages of interconnected systems. They are less expensive compared to leased lines and are often appropriate when there is low traffic, as well as for connecting several remote sites.
Techopedia Explains Switched Line
A switched line allows a physical transmission path to be established and dedicated to a single connection between two points of a network for the duration that the connection lasts. However, the switched network does not have dedicated links between the points or users, and therefore requires extra switching hardware.
