DLC (Digital Loop Carrier)
Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM.
A DLC system is a part of the copper-wire, local-loop telephone system. A DLC system aggregates the subscriber calls within a neighborhood, office building, or industrial park and multiplexes the calls over a single line (T1/E1 or fiber), back to the telephone company central office where all the switching equipment is located. DLC is an impediment to the expansion of DSL (Digital Subscriber Line) services. See "Telecommunications and Telephone Systems" and "DSL (Digital Subscriber Line)."
