Data transmission system

Abstract

Abstract PURPOSE:To transfer an inserted reception data block to a storage device by assigning transfer information of another channel to a reception data block of a frame belonging to other data block inserted between multiframes. CONSTITUTION:A communication control equipment 3 is connected to a transmission line in common use by a network via a transceiver 2 and a data transmission system is constituted by a data processor 5 and a storage device 6 connected via a bus 4. The communication control equipment 3 has a reception timing circuit 9, an address comparison circuit 11, a reception channel control circuit 12, an FES check circuit 13, a serial/parallel converting circuit 14, a reception FIFO memory 15, a reception DMA circuit 16 and a DAM cue table 17 and also consists of a transmission DMA circuit 18, a transmission FIFO memory 19, a parallel serial conversion circuit 21, an FCS generation circuit 22, a transmission control circuit 24 transmitting a timing signal 23.
