PURPOSE:To reduce the memory capacity in digital communication, which performs time sharing multiplex transmission in block unit, by providing specified two memories. CONSTITUTION:The receiver R is provided with the memory TSMa which can store the block number smaller than all the communication lines and greater in the channel number of transmission line TL. Further, the memory M storing the information storage address of this memory with the correspondence of the block number is provided. That is, the memory M has the area of all the communication channel numbers storing the information storage address when the communication channel and the block number are corresponded. Further, the readout information of the memory M is taken as the readout address of the memory TSMa to read out the information in block unit. Accordingly, as a result, the simultaneous communications having the same number as all the communication channel numbers can be made, the effective use of the memory TSMa is made and the memory capacity can remarkably be reduced. |
