    Abstract: The invention is a data multiplexing and separation method. It takes a plural number of timing data from memory that stores the plural number of timing data so as to detect bit positions on frame data signals on which bits respectively affiliated with a plural number of data are arranged. The plural number of timing data is used as the basis to arrange data to the frame data signal by successively arranging bits respectively affiliated with the plural number of data to the frame data signal so that the plural number of data is multiplexed to the frame data signals. And also it extracts a plural number of data from frame data signals by successively taking bits respectively affiliated with multiplexed the plural number of data from the frame data signals on the basis of the plural number of timing signals, and extracts a plural number of the multiplexed data from the frame data signals.

    Abstract: An ISDN network termination unit for connecting a user's bus line connected to a plurality of terminal equipments and a subscriber line extending from an exchanging office receives and transmits a D channel signal from one of the exchanging office and each terminal equipment to the other to thereby establish a data link between them on the D channel. The D channel signal is provided with an identifier code field. In order to establish a data link between the terminal equipments on the D channel without use of the subscriber line and the exchanging office, the ISDN network termination unit is provided with an identifier code holder for holding a predetermined identifier code and a deciding circuit for deciding whether or not the identifier code in the D channel signal from a specific one of the terminal equipment is equal to the predetermined identifier code. When both are equal to each other, the D channel signal is returned by a returning circuit to the terminal equipments through the user's line to thereby establish the data link between the specific terminal equipment and the other terminal equipments through the network termination unit. It may be made that a start flag and a stop flag are additionally detected so as to control the returning circuit.

    Abstract: A method and apparatus for determining whether a sufficiently clear digital path exists from a first end user to a second end user when connecting a call over a switched telephone network. Once the determination is made, the type of connection that is possible (high speed digital or analog compatible rates) can be determined. The present invention determines the characteristics of a path between two subscribers on a telephone network by transmitting a digital probe along the path. In cases in which an answering subscriber or the intermediate path are incapable of supporting a digital call, communication in accordance with a standard analog modulation scheme can proceed without having to redial the call.

    Abstract: 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.
