Abstract: PURPOSE: To attain reconstitution of a transmission line at each section even at a fault putting a communication system into pieces by providing a communication frame generating function and a compensating delay time to all communication controllers of each terminal station and providing a function relaying a communication frame.
CONSTITUTION: The function relaying the communication frame, that is, a func tion to be a master station is provided by providing a function generating a communication frame and a compensating delay time 13 to all the communica tion controllers 14 of each terminal station. When the communication frame is generated, an identification display to identify the communication controller 14 of a station from which the said frame is generated is added to the said frame. Each station detecting that the communication frame cannot be received due to a fault such as power failure becomes respectively a tentative master station to generate the communication frame and uses switches 10∼12, 20 to set a loopback line or bypass. Thus, even when a fault at which the communica tion system is divided into pieces takes place, the reconstitution of the transmis sion line at each section is attained.

Abstract: PURPOSE:To form the maximum highway from which a defective station node (SN) has been removed by using a self-transmission line switching function of an SN due to the fault of a transmission line to generate a false transmission line fault and switch the selecting system of SNs after the defective SN. CONSTITUTION:A false transmission line fault generating part 23 is formed on a station node SN and turns a switch SW2 or a switch SW3 on the basis of a false transmission line fault generating command from a supervisory unit SV. When the supervisory unit SV applies the false transmission line fault generating command to a station node SN1, transmission line faults are generated in respective nodes SNi after said node SN1 and the nodes SN2-SN5 detect the faults by respective supervisory parts LNCOs and turn the ''0'' system to the ''1'' system. Since the supervisory unit SV sends data to both systems, the nodes SN3-SN5 can receive data from the supervisory unit SV through the ''1'' system.

Abstract: PURPOSE:To reduce the time required for a node address and also to simplify the control by allowing the own node address to be written in an idle time slot when a node address check command frame from a supervising node is received at each node. CONSTITUTION:When a program control section 8 receives a node address check command from a supervisory node through a data region circuit 7, the section 8 changes over a selector 10 to the position of a data line 11 from the control section 8. When an idle time slot is searched by a data line 12 and it is found out, the own node address is written in the time slot via the data line 11, a flag is set and the time slot is brought into the busy state. The supervisory node reads sequentially the time slot of the frame where the node address is written to check the arrangement of nodes and node addresses connected to a highway. Thus, the time required for the check by the supervisory node is reduced.

Abstract: PURPOSE:To assign a line to a transmission side and a receiving side at nearly the same point of time by providing a channel address information storage part in a frame in a loop transmission system of the time division line exchange system having a supervising device. CONSTITUTION:The frame consists of a frame header FH and time slots TS0- TSl. The frame header FH is constituted by a synchronizing flag SYNC, a data part NT for communication between nodes, a trnsmission side address information storage part ADRS0 and a receiving side address information storage part ADRS1. The frame is formed and transmitted by a supervising station. When a transmission request is received from a station to other stations, the supervising station sets respectively a transmission side address and a receiving side address to the parts ADRS0 and ADRS1. When the receiving side is in a receptible state, it is informed to the transmission side by clearing the addresses.

Abstract: PURPOSE:To eliminate the need for level adjustment at the reception side, by measuring the photodetecting level of an optical signal from a transmission side node and controlling the output level of a transmitted optical signal from the transmitted node through the return of the result of measurement from the reception side to the transmission side, in an optical communication system. CONSTITUTION:Nodes 1-3 storing a plurality of terminal devices 7 are connected in ring shape by optical transmission lines 4-6 with an otical communication system, and a control code transmitted in the form of packet consists of a transmission number and information D discriminating a transmitted node from an incoming number DA and a transmission node from a terminal device. At the node 2, an optial signal L from the node 1 is converted into an electric signal at a photodetection section 11 and transmitted to a branch section 12, the photodetection level is measured, the esult LV is given to an encoding section 18 to detect whether or not the level is within the permissible range for encoding. Its code RL is assembled in a packet at a packet assembling section 15 and transmitted from an optical transmission section 17 to a transmission line. This is received at the node 1, an output control signal LC is sent to the section 17 based on the code RL to control the output level of the optical signal L.

Abstract: PURPOSE:To freely extend the distance of a cable independently of the number of signal lines of the cable, by enabling plural host processing units to use files in common, and using a bit serial transmission line. CONSTITUTION:An I/O instruction from a host processing unit 1 is set up in a register 14. The instruction is sent to a channel control word processing part 22 through conversion circuits 17, 16, so that channel control word existence address information is set up in a register 20 and transferred to a register 10 through conversion circuits 18, 15. Consequently a main memory is accessed and a channel control word is read out from the main memory and transferred to the channel control word processing part 22 through the conversion circuits 17, 16.

Abstract: PURPOSE:To prevent each local station from being completely isolated from a transmission line by providing each station with a means for returning the controlling information including a returning command to the transmission line and other information independently by a command from a monitoring station. CONSTITUTION:When a signal including a returning command CMDf is transmitted from a monitoring station (not shown) to a communication station STn through a signal line 0, said signal is outputted from the receiving terminal OR of a transmission unit T/R0 to a transmitting terminal OS and, simultaneously, inputted to a microprocessor MPU through a bus BUS. The MPU decodes the inputted signal and drives a relay winding RL1 in terms of time division through a relay driving circuit REG, so that a contact rl1 is switched under control like a dot line in the drawing so as to be folded only in the data area in a frame. Since the relay winding RL1 is not driven in the control signal area in the frame, said returning command signal is transmitted to a succeeding communication station through a contact rl0.
