Abstract
In a time-division multiplex transmission system, a host machine (3) and a plurality of addressable terminals (51 to 56) are connected together by way of a signal line (6). The same address (A) is assigned to a group of the terminals (51 to 54) so that the group of terminals (51 to 54) may be placed under control at the same time upon receipt of a transmission signal (SS) from the host machine (3). Reply signals (RS1 to RS4) from the respective terminals (51 to 54) are adjusted so that they are sent back at different points in time. This enables the host machine (3) to determine which of the terminals sent back the reply signal (RS1 to RS4).
