MULTI-ADDRESS COMMUNICATION EQUIPMENT

摘要

PURPOSE:To provide a multi-address communication equipment which can perform a multi-address communication with no influence of a copied multi-address cell given to other input cells in an exchange switch and also can omit the need to use a incoming line of the exchange switch for only input of the copied cell. CONSTITUTION:A multi-address communication equipment consists of an exchange switch 11 including a multi-address port 141 which outputs a multi- address cell and the normal ports 151-154 as output ports except the multi- address port, the selector means 121-124 which input the cells through the port 141 and one of ports 151-154 and select and output the cells received from both ports, and a control part 13 which points the multi-address cells to allow the pass of the means 121-124. Then the means 121-124 disuse the multi-address cells except the one that pointed by the part 13 among those cells which exist in each normal port and supplied from the port 141.
