A leased line is a telephone line that has been leased for private use.
In some contexts, it's called a dedicated line. A leased line is usually
contrasted with a switched line or dial-up line.
Typically, large companies rent leased lines from the telephone
message carriers (such as AT&T) to interconnect different geographic
locations in their company. The alternative is to buy and maintain
their own private lines or, increasingly perhaps, to use the public
switched lines with secure message protocols
