    摘要: A passive ISDN adapter card includes a serial controller (1) as is normally used to connect an external data transmission device; an ISDN data transmission controller (2) connected to the serial controller and controlled by the CPU of a computer (4); and an ISDN connection controller (3) controlled by the CPU of the computer (4) and connected to the data transmission controller (2). The ISDN adaptor card is compatible with a modem connected to the serial port without an INT-14-H interface for the evaluation process.

    摘要: Data received from a first layer is processed in a communication processor. Memory controller determines whether or not an instruction to be processed next by a processing circuit is stored in an internal RAM. When it is stored, it reads the instruction from internal RAM, and otherwise, it reads an instruction from an external ROM through an DMAC. Processing circuit changes setting of register values in respective registers in memory controller to values of the corresponding layer, when processing for one layer is completed. Consequently, the layer to be processed by the communication processor is switched.

    摘要: An application program interface for integrated services digital networks is implemented so that application programs can be generated independently of network protocols (Layer 1, 2; 1TR6, VN2) and independently of the respective implementation of service features. The application program interface contains for each network service an independent service program module (Telephony, FAX, Packet data, Teletex, . . . ) with a message set representing procedures as specified by standards (CCITT, ETSI, . . . ).
