Abstract
Abstract In a building subdivided into work stations (A1, A2) each work station is provided with at least one low voltage power supply outlet (12), at least one telephone socket (11), and at least one computer socket (10). The low voltage power supply outlet (12) is connected to a low voltage power supply bus (30). The telephone socket and the computer socket are portions of a precabling element which further includes a cable (1) having at least two pairs of wires for respectively establishing a telephone link and a computer link, and also having a connection module (2) at its other end. The entire precabling element (1, 2, 10, 11) is factory manufactured, thereby enabling any type of building to be cabled in a manner which is systematic, unspecialized, and reconfigurable.
