Design layout record

A Design Layout Record (also called by it's acronym, DLR) is used in the telecom industry and is used to describe the detailed design path of a completed telecommunications circuit, including all facilities from one end of the circuit to the other far end.

It may be detailed enough to include any location, floor, row, rack, panel and port or simply refer to another previously engineered circuit. In it's design, it's pieces may be comprised of physical or virtual circuits. As an example a physical facility would include a panel, rack & port. While a virtual facility may be a channel on a channelized circuit, such as a T1 on a previously engineered DS3.
