摘要： PURPOSE:To reduce the insertion loss due to interruption and to prevent the effect of an interference data terminal on a subscriber, by inserting a monitor amplifier to a subscriber terminal to be tested with the status information of the subscriber, before a line test trunk is connected to the subscriber terminal. CONSTITUTION:When a telephone number of a subscriber to be tested is dialed from a test board LTF, the number is received at a control circuit of an exchange via a line test trunk LTTA, the status information of the corresponding subscriber is transmitted to the line test trunk LTTA and displayed on the LFT. In case of a busy call, a relay MON of an accessory unit LTTAU is activated through an operating contact ''by'' of the relay of the trunk LTTA, and a monitor amplifier MNAMP is inserted to the subscriber line. Further, the controller of the exchange closes links 3, 4 between the subscriber terminal and the unit LTTAU after the transmission of busy information. Thus, a test personnel can monitor the line without giving adverse effect on other subscribers.

摘要： PURPOSE:To make a dial pulse reception circuit high in resistance, by setting a monitor output of a dial pulse to an optimum threshold level, through the constitution that digital conversion for an external voltage and the monitor of the dial pulse are performed in the same circuit. CONSTITUTION:A line test equipment LTE connected to a switch network is constituted with a high input impedance amplifier 1, a full wave rectifying circuit 2 rectifying AC signals, a smoothing circuit 3, a comparison circuit 4 comparing an output of the circuit 3 with that of a D/A converter 6, a digital control circuit 6, a DC/AC detection circuit 7 for an input voltage and a positive/ negative detection circuit 8 for the input voltage. In measuring the voltage of the line, the circuit 5 controls the converter 6 for D/A conversion, and in comparing a dial pulse, the circuit 5 stops the output of the circuit 3 and presets the measuring voltage of the line to the converter 6 and outputs the change in the dial pulse from the circuit 4. In this case, the monitoring output of the dial pulse is done with an optimum threshold level.

摘要： PURPOSE:To test a series of operations as the system automatically at all times, by starting a test attendant board periodically at a test incoming line trunk, and monitoring it at a check circuit. CONSTITUTION:In closing a key AR, a clock circuit 7 counts time in self-control, and a relay ST in a check circuit 6 is turned on and off. While the relay ST is activated, a test incoming line trunk 4 is grounded and a relay A is operated, a control circuit 8 illuminates the incoming lamp of a test attendant board 5 and monitors the response. Further, the check circuit 6 transmits ground to the control circuit 8 via a contact st through the operation of a relay P. When this earth signal connects the trunk 4 and the board 5 with the response of the control circuit 8 to activate a relay T. Since the relay P is restored with the operation of the relay T, an alarm relay AL is not operated, thus the normality is confirmed.

摘要： PURPOSE:To allow plural central processing units to use one input and output controller by providing a means of informing an interrupt report to a central processor in the input and output controller. CONSTITUTION:The central processing unit interface part 16 in an input and output controller 5 is provided with route FFs 0 and 1, which are set and reset under the control of the control part 17 of the controller 5 to store the conditions of a route. When a request for use arrives from an unconnected central processing unit between central processing units 1 and 2, the connected side is informed by interruption, etc., that the connected side is to be disconnected at a break of the processing of the input and output controller 5. Then, connection with the unconnected side is reported by interruption, etc. Thus, communication between the central processing units is unnecessary, and one input and output controller 5 is used by plural central processing units 1 and 2 without any complicated procedure and conflict.

摘要： PURPOSE:To send a talkie tone or a busy tone to a subscriber, by giving a 1- point control of a fault reception incoming trunk to incoming calls exceeding the waiting call numbers which are set previously without locking out said incoming trunk. CONSTITUTION:When a fault is reported from a subscriber of an unattended station, this report is connected to an incoming trunk 4 of a station in charge of maintenance via a switch 1 of the unattended station and an outgoing trunk 2. This maintenance charging station connects the report of fault to a test device rack 8 via a switch 5 and a fault reception trunk 7 and to a circuit device 13 and then to a test board 19 respectively. In this case, if the report of fault is given in an abnormal way from the subscriber, a control system device 16 within the device 13 discriminates a congestion state from the control quantity of the waiting call number which is held as a system. A congestion state is decided when the report of fault exceeds the control quantity of the waiting call number. Then a transmitting circuit is controlled to the fault reporting call which is received at a moment of congestion. Thus a talkie tone or a busy tone is transmitted to the subscriber who reported a fault.

摘要： PURPOSE:To prevent a system from breakdown and to specify a fault position, by connecting a common bus channel device to a common bus and a bus for an input and output controller, and thus preventing a bus fault of the input and output controller from extending to the common bus. CONSTITUTION:In the common bus control system wherein a central controller 3 is connected to the same bus with input and output controllers 9-13, and a main storage device 2, common bus channel devices 7 and 8 having an interface converting function or a data buffering function are connected to the common bus 1. Then, the plural input and output controllers 9-13 are connected in groups to the devices 7 and 8 through input and output buses 14 and 15. Consequently, a bus fault of the input and output controllers 9-13 never extends to the common bus, and the system is prevented from beins shut down to limit the fault range.
