摘要： The invention provides a bus line traffic control adapter apparatus which can secure a communications throughput of a data terminal which is already in a communicating condition even where there is a limitation in transfer capacity on a bus line. A first packet controller extracts throughput information in call user data in a call request packet. A traffic controller subtracts a current throughput value read out from a total throughput control section from allowable throughput information on a bus line, compares a value obtained by the subtraction with the throughput information notified from the first packet controller, and permits or rejects origination of a call in accordance with a result of the comparison. When a notification of rejection of origination of a call is received, the first packet controller cancels the received call request packet then and notifies a clear indication packet to the data terminal by way of a second ISDN control section.

摘要： A data terminal equipment which is coupled to an ISDN through an access line and uses a hierarchical protocol in conformity to an OSI reference standard model includes the following structural elements. A first data link protocol circuit provides a link access procedure balanced (LAPB) modulo-8 data link protocol. A second data link protocol circuit provides an LAPB modulo-128 data link protocol. A third data link protocol circuit provides a data link protocol based on a link access procedure for a data channel (LAPD). A protocol determining circuit determines a data link protocol to be used by referring to an address field and a control field of a cell set-up signal which is supplied from a second data terminal equipment. A data link protocol activating circuit selects and activates one of the first, second and third circuits on the basis of the result provided by the protocol determining circuit.

摘要： A facsimile terminal communicates facsimile data with an opposite facsimile terminal through an ISDN circuit. Even if the communication speed of the facsimile terminal is different from that of the opposite terminal, the facsimile terminal can surely exchange the facsimile data with the opposite terminal. The facsimile terminal includes a transmission and reception unit for transmitting and receiving data to and from the opposite terminal through the ISDN circuit, a receiving condition judging unit for judging or determining whether or not the transmission and reception unit receives data normally. The facsimile terminal also includes a speed switching instruction unit for providing a speed switching instruction when the transmission and reception unit does not normally or successfully receive data. In addition a speed switching control unit is provided for switching the communication speed of the transmission and reception unit from one speed to another according to the speed switching instruction.
