Subscriber loop carrier

A subscriber loop carrier or subscriber line carrier (SLC) provides telephone exchange-like telephone interface functionality. An SLC remote terminal is typically located in an area with a high density of telephone subscribers, such as a residential neighborhood, that is remote from the telephone company's central office. Two or four T1 circuits (depending on the configuration) connect the SLC remote terminal to the central office terminal (COT), in the case of a universal subscriber loop carrier (USLC). An integrated subscriber loop carrier (ISLC) has its T-spans terminating directly in time division switching equipment in the telephone exchange.
