    Abstract: PURPOSE:To improve reliability, by providing a shift register circuit to two pairs of transmission lines individually, erasing a GA code and decreasing the amount of hardware of a duplex loop transmission system. CONSTITUTION:Shift register circuits 5-1, 5-2 have bit length longer than that of the GA code given with the right of transmission, the GA code is received and the bit length of the GA code for erasing the GA code is required when the data to be transmitted from the calling station exists. A reception data is inputted to the shift registers 5-1, 5-2, a signal of an existing reception circuit 3-1 is inputted to a reception controlling circuit 6 with a selection circuit 4, and the data addressed to the calling station is transmitted to a common controlling section 10. The input data of the registers 5-1, 5-2 is outputted to transmission lines 1, 2 by transmission circuits 9-1, 9-2 via a switching circuit 8. The data of the register 5-1 is the GA code, and when a data transfer request signal is transmitted to a transmission controlling circuit 7 from the common controlling section 10, a transmission controlling circuit 7 transmits the signal.

    Abstract: PURPOSE: To check a small loop without requiring any address, by deciding whether a check message has been changed to a prescribed information or not when the check message which has been sent out to small loops formed into two transmission line loops in the reverse directions, respectively.
    CONSTITUTION: On loop transmission lines 1, 2 for transmitting a message in the reverse directions, respectively, transmission control devices 11∼16, 21∼26, and two-way alternative transmission lines 100∼600 are provided, so that small loops 201, 106, etc. are constituted. In order to check a state of the transmission line, a small check message LCM whose data part has been set to a numerical value of "0" is sent to the device 12 from the device 11. The device 12 receives it, adds "1" to the data part of the LCM and sends it to the device 22 through the alternative transmission line 200. In the same way, the devices 22, 21 add "1" to the received LCM and send it, respectively. The device 11 checks that the numerical value of the LCM, which has been returned is "3", and decides that the small loop 201 is normal. When the LCM which has been sent out is not returned even after a prescribed time has elapsed, the small loop concerned is decided to be abnormal.

    Abstract: PURPOSE: To reduce the processing time at compeition control of a control station, by transferring a transmitter to an operating system, when a transmitted signal of itself is detected with a device of itself.
    CONSTITUTION: When a clock is detected, a master stops the clock for a prescribed time, and transmits this information to a slave S. After a loop delay time, the slave S also detects the interference of clock and stops the clock for a prescribed time. The master M and the slave S transmit a time file, monitor the completion of PLL synchronization, and specific data A, B are transmitted when the synchronizm is detected. The slave S detects the data A and recognized the presence of the master M in the loop and transfers to the slave state. Thus, the both ends of the slave S is decreased, and the master M is transferred to the master state by the data A returned to the master M after circulating the loop.

    Abstract: PURPOSE:To increase the transmission efficiency, by transmitting test data to both duplicated system loop transmission lines with a fixed time interval, estimating the traffic with a time difference circulated with this test data, and selectively using the transmission line less in the traffic. CONSTITUTION:When transmission controllers 11-13, 21-23 perform reception only, a switch 61 is changed over to (a) side and in case of store-and-fo-ward mode, and switch 61 is changed over to (b) or (c) side. If transmission data are abundant (traffice is abundant) since each transmission controller is at store-and- forward mode, transmission delay is caused. Thus, each transmission controller transmits a test signal to both transmission lines 1, 2 prior to the transmission in advance and the time of circulation is tested, and when data is transmitted, shorter time of circulation is selected and used to make the traffic uniform.
