本発明はＤＴＭＦ （デュアルトーンマルチフリケンシ
）信号送出方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a DTMF (Dual Tone Multi Frequency) signal transmission system.

出先にパスを接続し、ＤＴＭＦ信号を送出していた。In the conventional DTMF signal transmission method, multiple senders (transmitters) that have all the sound sources (signal sources) are installed, and one sender is captured when sending a - group of signals, thereby creating a path to the signal destination. It was connected and was sending out DTMF signals.

ンダの実装数を増加する必要がある。In the above-mentioned DTMF signal transmission method, a plurality of senders having all the sound sources are installed, and by capturing one sender when sending a - group of signals, a path is connected to the signal transmission destination and the DTMF signal is transmitted. , the path and sender are released after all signals are sent. Therefore, not only is it necessary to capture and release the sender, but also the DTMF
When a large number of signal sending requests occur, a problem arises in which all the senders are in use, so it is necessary to increase the number of mounted senders in response to the amount of signal sending requests.

When transmitting a 40'' DTMF signal, the paths 18, 19, and 20 of the switch 13 are temporally switched from the sound source 1, 4, 11 corresponding to the dial number to the trunk 14, and
A DTMF signal of all dialed digits is transmitted to the trunk 14 of the connection destination via the switch 13. Also, sound sources 1 to 12
is capable of multiple connection with trunks 14 to 17, so when simultaneously transmitting a DTMF signal with the dialed number "158", the temporal path 21.22 from the sound source 1, 5.8 corresponding to the dialed number to trunk 16 is .23 are sequentially connected and a TDMF signal of all dialed digits is transmitted via the switch 13 to the connected trunk 16. At this time, sound source 1
simultaneously sends the dialed digits to trunk 14 and trunk 16. Note that the bus setting control of the switch 13 is performed by a control circuit (not shown) of the exchange according to the DTMF signal to be sent.
