摘要： The present invention relates to an interface apparatus between a digital computer and an analog communication medium. The interface apparatus has a telephony apparatus for transmitting or receiving the voice signals and a modem for transmitting or receiving the data signals. A switch is interposed between the telephone line and the modem and the telephony apparatus. The switch can be alternatively switched such that the telephony apparatus is connected to the telephone lines and transmits and receives voice signals and the modem is connected to receive data carrier signals that precede digital data signals and follow the digital data signals to and from the medium, or in the second position wherein the modem is connected to transmit and to receive digital data signals. The interface apparatus further has an interrupt for interrupting the operation of the computer and for causing the computer to be in communication with the modem and for switching the switch to connect the modem with the medium.

摘要： The present invention relates to a communication apparatus for transmitting and receiving analog voice and digital data signals to and from a telephone line or telephone lines to one or more users, in the same session. The apparatus has a telephony apparatus for transmitting or receiving the voice signals and a modem for transmitting or receiving the data signal. A switch is interposed between the telephone line and the modem and the telephony apparatus. The switch can be placed in a first position or in a second position. In the first position, the telephone apparatus is connected to the telephone lines and transmits and receives voice signals. In addition, the modem is connected to receive data carrier signals that precede digital data signals and follow the digital data signals to and from the medium. A control circuit comprising a microprocessor, controls the switch such that it can be switched automatically between the first position and the second position. The microprocessor changes the switch from the first position to the second position when the apparatus transmits digital data signals or receives the carrier signal indicating that digital data signals will be received by the apparatus. Upon termination of the transmission of the digital data signals from the apparatus or upon termination of the reception of digital data signals, the microprocessor automatically switches the switch back to the first position whereby voice communication can be continued.
摘要翻译：本发明涉及一种用于在同一会话中向一个或多个用户发送和接收来自电话线或电话线的模拟语音和数字数据信号的通信装置。该装置具有用于发送或接收语音信号的电话装置和用于发送或接收数据信号的调制解调器。电话线与调制解调器和电话设备之间插入开关。开关可以放置在第一位置或第二位置。在第一位置，电话设备连接到电话线并发送和接收语音信号。此外，调制解调器被连接以接收在数字数据信号之前的数据载波信号，并且跟随数字数据信号往返于介质。一种包括微处理器的控制电路，控制开关，使其能够在第一位置和第二位置之间自动切换。当设备发送数字数据信号或接收到指示数字数据信号将被该设备接收到的载波信号时，微处理器将开关从第一位置改变到第二位置。当数字数据信号从设备发送终止或数字数据信号接收终止时，微处理器自动将开关切换回第一位置，从而可以继续语音通信。
