ABSTRACT:
In order to extend a new unit to a telecommunication network comprising a plurality of units often distributed geographically and interconnected by means of transmission lines, or adapting the software of the various units, without causing problems with the control communication between the units, the control communication is divided into a number of successive levels, for each level, specifically for the lowest level while a code number belonging to the software of this unit is stored in each unit. Communication between two units at a specific level is only possible if the code numbers match and if at all lower levels communication already takes place.
