摘要： The present invention relates to an auto-detecting dialing communication system used to make the display of caller numbers in host or communication system consist with that of an extension telephone or communication system, especially relates to an extension telephone or communication system that can also display caller numbers. The present invention offer a device for auto-detecting dialing of a parallel communication system, which composes: (1) a FSK decoder for acquiring a dial-in number. (2) an extension telephone detecting device for detecting whether the extension telephone is off hook. (3) a memory for storing the caller telephone numbers. (4) a ring-back signal detecting device for examining whether a ring-back signal is sent back. (5) a Dual Tone Multiple Frequency (DTMF) decoder for acquiring the outgoing call number. (6) a processor for sequentially proceeding with output signals of the FSK (Frequency Shift keying) decoder, the extension telephone detecting device, the memory, the ring-back signal detecting device and the DTMF (Dual Tone Multiple Frequency)decoder according to an order.
摘要翻译：本发明涉及一种用于使主机或通信系统中的主叫号码的显示与分机电话或通信系统的自动侦测拨号通信系统组合在一起，特别涉及还可以显示呼叫者的分机电话或通信系统数字。本发明提供一种用于自动检测并行通信系统拨号的装置，其组成：（1）用于获取拨入号码的FSK解码器。（2）用于检测分机电话是否摘机的分机电话检测装置。（3）用于存储呼叫者电话号码的存储器。（4）回铃信号检测装置，用于检查回送信号是否被发回。（5）用于获取呼出号码的双音多频（DTMF）解码器。（6）根据本发明的一个处理器，用于依次执行FSK（频移键控）解码器，分机电话检测装置，分机电话检测装置，存储器，回铃信号检测装置和DTMF（双音多频）解码器的输出信号订购。
