Abstract
In a communications environment where it is desirable to allow the simultaneous transmission of digital subscriber line (DSL) signals and conventional Plain Old Telephone Service (POTS) signals on a single two-wire communication line, a method and apparatus is configured to automatically measure the distortion caused by a telephone or other attached device such as a dial modem due to the presence of a DSL signal on the same communication line. The method and apparatus of the present invention allows DSL devices and POTS devices to be used on the same communication line without the use of a splitter.
