Quizplus · Accepted Answer

A leased line requires a CSU/DSU (channel service unit/data service unit) at each site. A CSU/DSU is used to convert the digital data from the customer's equipment into a format that can be transmitted across the leased line. It also performs line equalization, impedance matching, and error correction functions. Switches, routers, and modems may also be used in conjunction with a leased line, but they are not required.
