    Abstract: PURPOSE:To secure a coincidence of the transmission velocity between the transmission and reception without transmitting any information regarding the transmission velocity, by securing such constitution in that only the receiving circuit having a velocity equal to the transmission velocity of the transmission side delivers the data. CONSTITUTION:The receiving circuit 1 includes the start bit detecting circuit 5 and stop bit detecting circuit 6 which detect both the start bit and the stop bit out of the transmission data sent via the line 4 each plus the serial-parallel converter 7 which converts the serial trasmission data into the parallel reception data. The receiving circuit 2 also incorporates the start bit detecting circuit 8, stop bit detecting circuit 9 and the serial-parallel converting circuit 10 respectively. Thus the zero-code equivalent to one character and sent from the transmission side is received, and only the receiving circuit having a transmission velocity equal to that of the transmission side delivers the data.

    Abstract: PURPOSE:To improve the use efficiency of a memory at the time of data structure conversion by reserving the area of the total sum of calculated fixed areas and variable areas in the memory and transferring analyzed message data to a corresponding area to convert it to internal data. CONSTITUTION:Additional information is added to the message from a computer, which is received by a line control part 22-1 on the computer side, by the control part 22-1 and this message is sent to an ROS control party 22-2, and it is checked whether the message accords with ROS procedures or not; and when it accords with them, it is sent to a computer-side message converting part 267 and is converted to internal structure data. In this processing, the memory area for storage of the data structure to which message data is converted is calculated, and the calculated area is reserved in the memory. The message main body is subjected to branching processing and analysis, and field information is extracted and is stored in a corresponding area of the memory. Data converted by the converting part 26 passes a preprocessing part 28 and a converting part 30 and is converted to the format of the exchange side by a converting part 32 and is sent to the exchange side through an interface circuit 24.

    Abstract: PURPOSE:To offer a high-grade service by providing a call state information destination control table in an interface arranged between a communication system and an information processing system, detecting a call state set in the table and giving the information of it to the information processing system. CONSTITUTION:The interface 4 is arranged between the communication system 2 and the information processing system 5 and the call state information destination control table 4-1 which sets a call state information condition and an information destination in accordance with call numbers is provided in the interface 4. Then, the communication system 2 and the information processing system 5 share a function by referring to the call state information destination control table 4-1 in correspondence with the transition of the call state informed from the communication system 2 and giving the information of the call state to the information destination concerned of the information processing system.

    Abstract: PURPOSE:To allow the system to cope with a protocol change through program change only by programming the conversion procedure of a protocol and executing the program on the interpreter (language processing system) and running the program on the system. CONSTITUTION:A conversion procedure of a protocol is registered in a sequence table 63 of a protocol processing unit 6. Then the message received from an exchange by an interface 61 is converted into a form able to be processed by an interpreter 62, analyzed and the relevant sequence is found out from a sequence table 63 and a command is extracted from the sequence table 63, interpreted and executed. Moreover, a transmission message is converted into a form of the computer side at the interface 61. Then the conversion method of the protocol is described by the programming language to easily change the protocol by the program change.

    Abstract: PURPOSE:To effectively utilize a terminal and to improve business serviceability by applying an instruction to an application processor by means of the control of an exchange when an incoming call arrives at the terminal of an ISDN, fetching information concerning a transmitting terminal, and display the information on an arriving terminal. CONSTITUTION:When dial information to designate the opposite terminal is received from the exchange, which is not shown in a figure, a transmitting terminal number and a receiving terminal number are inputted to an exchange control part 13, and the call request of the data concerning the transmitting terminal is applied together with the transmitting terminal number and the receiving terminal number to an application processor 15 by a built-in transmitting terminal information call requiring part 131. A data control part 151 of the processor 15 drives an incoming data terminal retrieving part 153, fetches data 161 concerning the transmitting terminal in a data base 16, sends them to the control part 151, outputs a bus connecting request to the control part 13, controls a channel part 14, and the transmitting terminal data are displayed on a display means 101 of an incoming data terminal 10. Thus, the data can be made visible as well together with the telephone number of the transmitting terminal displayed at the time of the incoming call.

    Abstract: PURPOSE:To attain the communication again with a transfer sender subscriber by allowing the transfer sender subscriber to execute a prescribed operation if the communication with a called subscriber is disabled after the transfer sender subscriber is restored. CONSTITUTION:A transfer destination extension 2c executes a predetermined operation, hooking to request a callback of a transfer sender extension 2b when a busy tone is returned, executes the incoming processing to the transfer sender extension 2b and sends a call signal to the transfer destination extension 2c. Upon the detection of a reply of the transfer sender extension 2c, an RCB 124 sets a channel P2 again in a network NW11 to connect the transfer sender extension 2b and the transfer destination extension 2c. Being informed of the disabled communication with a called extension 2a from the transfer destination extension 2c, the transfer sender extension 2b applies hooking again, dials an extension number given to the called extension 2a to call the called extension 2a to request the communication with the transfer destination extension 2c.
