摘要： PURPOSE:To make it possible to connect freely a trunk to the terminal of a line network by allowing a subscriber's-telephone equipping terminal to make the contact of a cut-off relay and to disconnect a trunk equipping terminal on the end of a call. CONSTITUTION:Subscriber scanner 8 detects the call of a subscriber's telephone set by the automatic switchboard of a store control type, and channel driver 7 controls the connections among channels. On the basis of driving information fixed according to units equipped to respective terminals of the line network, contact 6 of the cut-off relay for the control of the subscriber scanner is so controlled that the subscriber's-telephone equipping terminal is closed and the equipping terminal for trunk 1 is open. Consequently, trunk 1 can freely be connected to line network terminal without remodeling a jumper terminal.

摘要： PURPOSE:To realize a highly reliable traffic control system by securing the outgoing control over a wide range and then incorporating the high-degree decision of man into the system in addition to the decision of machine. CONSTITUTION:With detection of the congestion via DET added to the exchange of LS, the known multi-frequency code is used to CONT to transfer the congestion information. Receiving the congestion information, CONT compares the subscriber number and its frequency beta through which incoming register group full busy time rate alpha in the information and the busy frequency of a prescribed circuit within a fixed period are observed with preset congestion detection threshold level alpha0 and beta0. If the congestion is decided through the comparison, CONT delivers the prescribed control rate gamma0 to then inform it to TTY and CONT-A to CONT along with the information received through DET via the existing data transmission system, a and at the same time transmits the outgoing control information to RCIE.

摘要： PURPOSE:To attain ease of extending job of a unit by connecting a unit mounting section and a selection with a connecting line having the maximum number of storage lines per unit and providing an address converting section between an address generating section and the selection section. CONSTITUTION:The selection section 13 and the unit mounting section are connected in advance by mXn of connecting lines S11-Smn, where (m) is the maximum mounting number of the units 14 and (n) is the maximum number of storage lines per unit, and the address generating section 12 is constituted to generate an address signal corresponding to the maximum number storage line (p). The address converting section 15 consists of memories or the like, the address signal is converted to designate a line individual section of the mounted units and its signal is supplied to the selection section 13. An address designating the line individual section is written in the said memory MEM. Thus, the connection between the selection section 13 and the individual section is performed by only mounting the units to the unit frame, the address signal is converted at the conversion section 15 by writing the address of the line individual section in the unit to the memory MEM, and the line individual section is designated without designating an idle connecting line.

摘要： PURPOSE:To realize the combination of the public and general circuits without impairing the call loss and the attenuation distortion in the general-public circuit combination system. CONSTITUTION:Charging pulse transmission circuit 8 is provided to the local oscillation public telephone unit and then stored in network (NW) 3, and then circuit 8 is interrupted into the public circuit to carry out the transmission control for the charging pulse. To perform the transmission control for the charging pulse, the interruption state (parallel connection between circuit 8 and outgoing trunk or local trunk 7) is produced in NW3, and the call current is supplied in parallel through circuit 8 and trunk 2 or 7. After this, the relays for current supply and the subscriber supervisory inside circuit 8 are cut off, and the supervisory relay is turned on again after transmission of the charging pulse to cancel the interruption state. As a result, the installation of circuit 8 for each trunk can be omitted via the general or local trunk plus the interruption system.

摘要： PURPOSE:To improve the call loss and the attenuation distortion by realizing both the public local connection call and the public outgoing connection call formed with the loop round connection of the general outgoing trunk and the tandem outgoing trunk through each different pattern state. CONSTITUTION:In the state of pattern ''2'' in the Karnaugh map, only pattern relay T operates. This suited for execution of the outgoing connection call to the tandem outgoing trunk through the loop round connection. Under these conditions, the preceding monitor and charging pulse sending circuit 1 are just inserted between call lines A and B of public charging local trunk IOT-CH8, and call capacitor C3 is by-passed by T contacts t2 and t3. And next monitor relay 2 is cut off from A and B via T contacts t0 and t1. Accordingly, no overlap is caused between circuits 1 and 2 plus C3 when the outgoing connection call is given between IOT-CH and the tandem outgoing trunk, and the connection is given between two trunks 7 and 8. As a result, both the call loss and the attenuation distortion can be improved for the long-distance call which is performed via the tandem outgoing trunk.

摘要： PURPOSE:To transmit plural frequency-modulated signals to a transmitting circuit with a simple constitution without providing frequency modulators corresponding to circuits, by connecting a frequency modulator to the transmitting circuit for frequency-modulated signals only when transmitted data is present. CONSTITUTION:A transmitting circuit group 1 for frequency-modulated signals is connected to a connection switching device 4 and when there is no transmitted data from transmitting circuits #1-#N, all the circuits #1-#N are connected to the carrier frequency oscillator 2 through the device 4 to generate a carrier frequency output. Once the transmitted data is generated, a controller 5 sends an indication to the device 4 through a control line 6 to switch and connect only the corresponding circuits #1-#N through the device 4 to a frequency modulator 3 and after the connection ends, the controller 5 sends the transmitted data to the modulator 3 through a signal line 7 to transmit the frequency- modulated signal to the circuit group 1. Thus, the transmitted data generated intermittently is sent out effectively through the simple constitution without provided modulators corresponding to the circuits.

摘要： PURPOSE:To prevent abnormal origination-side traffic a switching network has in a short time, by providing an automatic originating device with a simultaneous oscillation control mechanism. CONSTITUTION:From computer center 3 to control part 7 of automatic originating device 6, requests for sound information are sent at a time. Control part 7 controls circuit correspondence part 9 to send the subscriber's telephone number of subscriber terminal 1 to be called to exchange 2. At exchange 2, the circuit is considered to be in an origination completion state when originating request calls exceeding a simultaneous origination permissible number are put in a queue by holding origination requests and a call in process of origination request processing enters in a call state or talk state during the said procedure of the transition to a called- subscriber calling state and a talk state by a called-subscriber's answer via a switching network. The current number of calls in simultaneous origination decreases correspondingly. Therefore, the origination request for a call placed in an origination request holding state is enabled and originating operation is started.

摘要： PURPOSE:To enable transmission to subscriber terminal registrated based on the transfer information, by providing the information memory section registrating the transfer information to the subscriber terminal having the automatic transmission functions. CONSTITUTION:The subscriber terminal 1 which stops the automatic transmission operation through the automatic transmission functions and no response of called subscriber terminals is provided with an information memory section 18 which registrates the transfer information including the subscriber number of the subscriber terminal, the subscriber number to be transferred and the transfer service information based on the request from arbitrary subscriber terminals 6, 8. Further, in the transmission from the subscriber terminal 1 to arbitrary subscriber terminals 6 and 8, if the transfer information as to the incoming subscriber terminal is registrated in the information memory section 18, automatic transmission is made with transferred subscriber number based on the transfer service information.
