Abstract

The method consists of a fibre optic system with one or two fibres and TOMA transmission to which a new remote unit can be added or whose remote unit service can be reset without producing a cut-off or error rate in the communication between the other remote units and the central unit it is used to measure the propagation time between a remote unit and a central unit and program the appropriate delay in the remote unit.
