ABSTRACT:
A network administration system includes a network of a plurality of cascade connected repeaters for functional terminal units, and an administrative terminal connected through a transmission path to the network for administrating the network of the repeaters and terminal units, the system being arranged for transmitting from said administrative terminal a command packet to the network for recognition of connecting arrangement between the respective repeaters and terminal units, returning from the network a return packet to the administrative terminal in response to the command packet, and analyzing in the administrative terminal the return packet for automatically recognizing the connecting arrangement in the cascade connection of the repeaters and terminal units included within the network and precisely locating one of the repeaters and one of its connecting ports to which one of the terminal units involving a trouble is connected.
