carrier serving area

A geographic customer area that is consolidated into a single digital transmission by the telephone company. Each carrier serving area (CSA) is served by a digital loop carrier (DLC), which multiplexes hundreds of analog lines into one high-speed digital trunk. The physical size of a CSA is based on the number of lines the DLC supports and the population density. See central office.
