Data transmission system and equipment
First Claim
1. A data transmission system in which the physical location of a data terminal means connected to the system can be identified, said system comprising:
- a data transmission network (13) having a plurality of data communication connection points (18) for transmitting and/or receiving data, each of said connection points being located at a physical location served by said data transmission network;
at least one data terminal means (16) connectable to the data transmission network at a selected one of said connection points (18) for receiving and/or transmitting to or from the network; and
means for providing, to the data transmission network, an identification of the physical location of the selected connection point to which the data terminal means is connected, said means comprising a coding element (15) located at said selected connection point, said coding element being non-integral with said connection point, said coding element having contained therein an encoded address identifying the physical location of the selected connection point, said coding element being connectable to said data terminal means when said data terminal means is connected to said selected connection point for supplying said encoded address to said data terminal means for provision to the data transmission network as the identification of the physical location of the selected connection point to which the data terminal means is connected, said coding element being non-integral with said connection point when said data terminal means is disconnected from said selected connection point.

Abstract
The object of the invention is a data transmission system for the identification of the location (20) of the data terminal equipment (16). The system comprises the data terminal equipment (16) which operates according to the instructions given by a program, the data network (13) for the transmission of the data between the data terminal equipment (16) and, data network connection points (18), adapted to forward communication, and to which there is a connection from the data terminal equipment, an element (14) linked to the data terminal equipment, correspondingly adapts the communication to be transferred to the data terminal equipment and network. The invention is characterized in that a coding element (15) can be linked to the data terminal equipment to be connected to the network, from which coding element the physical address of the equipment location (20) can be read into a transmittable communication.
