PURPOSE:To enhance the line efficiency due to transmission of collective information and give group selectivity to a terminal equipment to improve the use efficiency by providing plural group address storage parts in the terminal equipment in case of transmission of the same information. CONSTITUTION:A group address 11 and a peculiar address 12 are given to a transmission control part 20 together with data 13 and are transmitted. In the terminal equipment, transmission address information is received by a group address comparator 14 and is compared with information in a group address storage part 15 for peculiar addressing. This comparison means comparison with the group address 11; and if comparison results in coincidence, a peculiar address comparator 17 is indicated to compare the peculiar address. If said comparison does not result in coincidence, contents of group address storage parts 16 and the group address 11 are compared with each other successively by the comparator 14, and data processing is performed if the group address 11 coincides with one of them. |
