<p>PURPOSE:To connect one terminal equipment and plural terminal equipments simultaneously without revamping an existing packet exchange by setting a different logic channel from each destination with a packet exchange and storing it till at least the end of communication when a call request is addressed to plural destinations. CONSTITUTION:A CR packet is generated respectively for each terminal equipment and an address of each opposite terminal equipment is inserted respectively to the CR packet. Then number of idle logic channels is selected by number of CR packets among all logic channels available with a packet exchange X, identification information of the logic channel is inserted one by one and the resulting packet is sent to the packet exchange X. Moreover, an interface module 11 stores identification information of a logical channel set between a said protocol converter P1 and the interface module 11 corresponding to the logic channel identification information for each opposite terminal equipment set between the interface module 11 and the packet exchange X.</p> |
