ABSTRACT:
A modular coupling unit which functions as an interface between a communication unit or peripheral apparatus and the communication network includes a code word signal generator for generating a unique address code which is representative of the geographical location in which the relevant coupling unit is "permanently" included in the communication network. This signal generator is and continues to be energized as soon as and for so long as a communication unit or peripheral apparatus is and has been connected to the coupling unit. The address codes generated in bursts by such a generator are transferred via a connecting cable between the relevant communication unit and the coupling unit to this communication unit. The relevant address code is stored in the coupling unit. On request and within the time regime holding for the communication network, the address code is read and transferred to a diagnostic module via the communication network. Thus a geographical survey of the communication network with the peripheral apparatus connected thereto can be obtained. The geographical address of a communication unit in which a disturbance has occurred can thus be determined, using an error search algorithm.
