摘要： A method and a system for bidirectional transmission/reception of data between two terminal stations, in which each transmission period is divided into a plurality of first time sections for relatively low speed data transmission and at least one second time section for relatively high speed data transmission, the direction of transmission between the terminal stations being predetermined in each of the first time sections, while the direction of transmission between the terminal stations is reversible in each of the second time sections, each second time section being preceded by one of the first time sections. Transmission of information data and control data is performed from one to the other terminal station in a predetermined direction in each first time section, and the direction of data transmission between the terminal stations in the next second time section is determined on the basis of control data contained in the relatively low speed data transmission.

摘要： This invention relates to a time division switching system for exchanging audio signals, data and so on in a time division manner. This time division switchboard comprises a plurality of separate local exchange units capable of interfacing with various different circuits such as subscriber lines, trunk lines, service circuits and so on, one or a plurality of junctor high ways connected to a time switch of each of the local exchange units, and one or a plurality of tandem exchange units each having a time switch connected to the other ends of the junctor high ways and switching by the time switch. Each of the local exchange units selects a channel on an arbitrary junctor high way and transmits control information concerning other one of the local exchange units to which a calling is to be sent, to one of the tandem exchange units which has the selected junctor high way connected thereto. The tandem exchange unit to which the control information is sent selects a channel on a junctor high way connected to the local exchange unit to which the call is to be sent, in response to the control information sent thereto, thereby switching the calling to the desired local exchange unit. Thus, since the respective units can be loosely coupled to each other, the time division switching system of this invention has high reliability and good economy.

摘要： In a communication system having a base station for controlling a transmission right and a plurality of substations, a substation having data to be transmitted transmits the number of necessary fragments and its address to a request field of a communication frame. The base station uses a plurality pair of fragment slots and reply slots following the request field in the communication frame to transmit an address of a substation permitted to transmit data, to each fragment slot. The substation permitted to transmit data transmits the address of a destination substation and the data to a predetermined field following the address in one fragment slot. The destination station transmits a reply signal indicating the reception state of the data to the reply slot paired with the fragment slot. If the base station detects from the reply signal that the destination station failed in receiving the data, the base station instead of the substation first transmitted the data transmits the destination address and data received at the fragment slot to the next fragment slot.
