Abstract

PURPOSE:To improve the communication efficiency by providing a communication controller beween loops in a fixed assignment time division multiplex loop transmission system. CONSTITUTION:In transmitting data from a communication station 1 to a communiction station 6, the communication station sets data to a slot #1 in a transmission frame circulating in a loop form transmission line by using a destination station as the communication station. The communication controller between loops decodes the data of the said slot #1, detects that the data is data to other loop form transmission line and sets the data to the slot #3 in the transmission frame circulating the loop form transmission line. The controller between loops sets similarly the data to the slot #3 in the transmission frame circulating the loop form transmission line. The communication station detects and receives the data of the slot #3 in the transmission frame by taking the data as data addressed to the own station.

欠点があった。Since data transmission is performed between each communication station (11 to (8)) as described above, even in a system where communication stations with high communication frequency and communication stations with low communication frequency coexist, for example, communication station (1) Regardless of the communication frequency, even if the communication frequency is high between the communication station (2) and the communication station (3) and the communication station (4) group, and there is almost no communication between other groups. All the communication stations are connected within one loop-shaped transmission path, and in the transmission frame, it is necessary to allocate slots If to the M station side, so the transmission frame becomes long and the frame rotation speed becomes slow. There was a drawback.
