<p>In a plurality of terminal equipments 1-1 connected to one line, in each of the terminal equipments a delay time T2 by which a response from the terminal equipment when in an abnormal state is delayed, is preset. When a message arrives at the plurality of terminal equipments TEA...TEH through the one line, an abnormal terminal equipment returns a response delayed by the above-mentioned delay time T2, and a network transmits a response acknowledgement to only one terminal equipment which returns the earliest response. Only the terminal equipment receiving the response acknowledgement can communicate with other terminal equipment connected to another line through the network 15. By using the above-constituted invention, when the plurality of terminal equipments 1-1 are connected to the one line, the response from an abnormal terminal equipment is delayed and a normal terminal equipment can receive the message. <IMAGE></p> |
