【発明の詳細な説明】
本発明は4線式音声専用回線をもちいて交換接続用のシ
グナリングパルスを伝送する装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for transmitting signaling pulses for switching connections using a four-wire voice dedicated line.
従来このような装置として、音声帯域内に特定の周波数
を持つシングルトーンを、シグナリングパルスに応じて
断続させて伝送し、受信側にてこれを整流検波して元の
シグナリングパルスを再生する方式は公知である。Conventionally, such a device transmits a single tone with a specific frequency within the voice band intermittently according to the signaling pulse, and the receiving side rectifies and detects this to regenerate the original signaling pulse. It is publicly known.
伝送回線は通話音声との共同使用が通常である為、この
方式は通話音声及び音楽9口笛、警笛等の周囲雑音によ

スによって直接キーイングしている為、信号エレメント
の継続時間が短く、受信側で十分なガードを施すことが
できない故に、誤動作率を低下させることが困難であっ
た。Since the transmission line is usually used in conjunction with voice calls, this method has the disadvantage of a high malfunction rate due to ambient noise such as voice calls and music9 such as whistles and horns. In addition, methods have been put into practical use, such as a method in which two or more tones are intermittent at the same time instead of the single tone mentioned above, or a method in which intermittent pulses are transmitted as FM modulated waves, but both methods involve direct keying using manual pulses. Because of this, the duration of the signal element is short and sufficient guard cannot be applied on the receiving side, making it difficult to reduce the malfunction rate.
本発明は、このような欠点を除去する為に、シグナリン
グパルスを1桁ごとにまとめて、音声及び雑音による誤
動作が生じにくく、また受信端で誤り検定が可能なよう
な信号に変換して伝送する信頼度の高いシグナリングパ
ルス伝送装置を提供することを目的とする。In order to eliminate such drawbacks, the present invention collects signaling pulses for each digit and converts them into a signal that is less likely to cause malfunctions due to voice and noise and that allows for error checking at the receiving end before being transmitted. The purpose of the present invention is to provide a highly reliable signaling pulse transmission device.

するような構成とするものである。The present invention counts signaling pulses digit by digit at the transmitting end, converts them into tone signals of two or more waves having a predetermined combination of frequencies according to the number of signals, transmits them digit by digit, and then transmits the signals at the receiving end. The configuration is such that M signaling pulses are generated by detecting the M signal pulses.

The human-powered signaling pulses are counted digit by digit by a pulse counter indicated by 1, converted to parallel signals such as BCD, and then converted to DTMF (Dual Tone Muti) indicated by 2.
Frequency) The generator is fully driven. This DTMF generator is the same as the one used in subscriber telephones called ``6 pushphones'', and has only one input.
,2. 9°0, one wave out of four predetermined low group frequency waves and one wave out of three high group frequency waves are output simultaneously. There is no harmonic relationship between these two waves, and the combination is such that voice and other noises are difficult to create a pseudo signal. Since the digit interval of the human-powered signaling pulses is set at a certain time or longer, the duration of the output dual tone can be sufficiently long.

、2波の正しい組み合せが一定時間(ガード時間)継続
して始めて出力が有効となる様な構成になっている。The signal transmitted through the audio line is detected by a DTMF receiver shown at 3 and converted into a parallel DC signal such as BCD. This DTMF receiver is the same as the one used by the telephone office to support "one-button telephones", and it is disabled if the receiver's power is only one wave, or invalid if there are three or more waves, and the correct combination of two waves is fixed. The configuration is such that the output becomes valid only after a continuous period of time (guard time).

パルスレートを以って接続することが可能となる。This output drives the pulse dialer shown at 4,
It is regenerating a signaling pulse similar to the one that entered the transmitting end input. This pulse dialer is also the same as that used in the "1st pseudo-button" telephone that connects to a rotary dial telephone line, and the output pulse rate can be selected, so the input at the transmitting end and the output at the receiving end can be selected. It becomes possible to connect with different pulse rates.
送信端入力と受信端出力の双方を、今まではシグナリン
グパルスとする場合について説明したが、いずれか一方
はデュアルトーンとしてもよいことは当然である。この
場合のトーンの周波数と組み合せが、伝送路で使用する
ものと一致しているならば、装置の構成がより簡単かつ
単純なものとなる。Although the case has been described so far in which both the transmitting end input and the receiving end output are signaling pulses, it goes without saying that either one may be a dual tone. If the tone frequencies and combinations in this case match those used in the transmission path, the configuration of the device will be simpler and simpler.

式のそれのほぼ2乗となり、よシ高い信頼度の装置を構
成することができる。Also, if each digit is temporally divided into two time slots, and dual tones with different combinations are transmitted in the first half and second half, and one of them is used as a check code, the malfunction rate due to noise etc. is approximately the square of that of the 1-time slot transmission system, making it possible to construct a highly reliable device.
