Abstract

PURPOSE:To obtain a time-division multidirectional multiplex communication equipment which enables channel assignment contents to be modified without stopping the operation of the equipment, by modifying the channel assignment contents by an external control signal. CONSTITUTION:A storage circuit 3 is used to store data on channel assignment, and storage circuit groups 41-4n equipped to a master and a subordinate station store different channel assignment contents. The readout contents of the storage circuit 3 are supplied to a selecting circuit 5. One of channel assignment contents of storage blocks 41-4n supplied to the selecting circuit 5, for example, the channel assignment content of the storage block 41 is selected by an external selection signal (a) and outputted. Therefore, (n) kind of selection signals (a) are supplied from the outside to selectively output corresponding channel assignment contents.
