Abstract

A system for location identification in a local area network comprising: a current limited voltage source; a telecommunications outlet; communication cabling connecting the current limited voltage source to the telecommunications outlet; and a location identifier associated with the telecommunications outlet, the location identifier being responsive to a pre-determined voltage level from the current limited voltage source to transmit a multi-bit location data. In one embodiment the multi-bit location data is received at the power sourcing equipment and in another embodiment the multi-bit location data is received at a data terminal equipment connected to the telecommunications outlet.
