On the other hand, in the manhole, a receiving side tester 24 having a receiving side telephone 24a connected by a cord 24b is prepared, and the receiving side tester 24 is connected to the test telephone line 22a of the communication line 22. Confirm the call (conversation) between the workers in the (NTT Building) and the workers in the manhole.
【０００９】 つぎに、電話局（ＮＴＴビル）側の作業員は、通信線２２の特定の通信線２２ に、送信側試験機２３を接続線で接続し、接続したことをマンホール側の作業員 に伝える。 これを聞いたマンホール側の作業員は、前記所定色で区別された通信線２２か ら、おおよその通信線２２に、探針（ピックアップ）２５ａを接触または近づけ る。 探針（ピックアップ）２５ａを接触または近づけた通信線２２が、送信側試験 機２３からの試験信号であった場合には、前記発信回路による発信信号が連続音 として、送信側通話機２３ａと受信側通話機２４ａから聞こえ、１本の通信線２ ２の通線確認が終了する。Next, a worker at the telephone office (NTT building) connects a transmission-side tester 23 to a specific communication line 22 of the communication line 22 with a connection line, and indicates that the connection has been made. Tell The worker on the manhole side hearing this touches or brings the probe (pickup) 25a into or out of the approximate communication line 22 from the communication line 22 distinguished by the predetermined color. When the communication line 22 to which the probe (pickup) 25a has been brought into contact or brought close is a test signal from the transmission side tester 23, the transmission signal from the transmission circuit as a continuous sound is received by the transmission side talker 23a. The call is heard from the side communication device 24a, and the confirmation of the passage of one communication line 22 is completed.
【００１０】 １本の通線確認後、電話局（ＮＴＴビル）側の作業員は、通信線２２内の次に 特定した通信線２２に送信側試験機２３を接続する作業を行い、接続したことを マンホール内の作業員に伝える。 マンホール側の作業員は、電話局（ＮＴＴビル）側からの連絡があると、前記 探針（ピックアップ）２５ａを前記通信線２２内の特定の通信線２２に接触また は近づける。 このような通線確認作業を通信線２２の全の通信線２２に行うと、通信線切替 工事に伴う通線確認作業が終了する。 そして、電話局（ＮＴＴビル）間に次の中継箇所（マンホール）がある場合に は、マンホール内の作業員は、次の中継箇所であるマンホールに移動し、上記同 様の通信線切替工事に伴う通線確認作業を行う。After confirming one line, the worker at the telephone office (NTT building) connects the transmission-side tester 23 to the next specified communication line 22 in the communication line 22 and connects.

【００１１】[0011]
しかしながら、上述した通線確認装置２１では、送信側通話機２３ａは電話局 （ＮＴＴビル）内に配置された送信側試験機２３にコードで接続され、受信側通 話機２４ａは、マンホール内に配置された受信側試験機２４にコードで接続され ているため、電話局（ＮＴＴビル）内の作業員は、送信側試験機２３の近傍から 離れることができず、マンホール内の作業員は、受信側試験機２４の近傍から離 れることができないという問題があった。 例えば、電話局（ＮＴＴビル）内で通線確認作業の準備等を行っている間は、 マンホール内の作業員は、局内での準備が終了するまで、受信側通話機を装着し たまま受信装置の近傍を離れることができず、ただ、「準備完了」の応答がある まで待っていなければならなかった。 However, in the above-described line checking device 21, the transmitting side telephone 23a is connected by a cord to the transmitting side tester 23 disposed in the telephone office (NTT Building), and the receiving side telephone 24a is disposed in the manhole. The worker in the telephone office (NTT building) cannot leave the vicinity of the transmitter 23 because the cord is connected to the receiver-side testing machine 24 that has been received. There is a problem that it cannot be separated from the vicinity of the side tester 24. For example, while preparing for line checking work at the telephone office (NTT Building), workers in the manhole receive the telephone while wearing the receiving telephone until the preparation in the office is completed. I could not leave the vicinity of the device and just had to wait for a "ready" response.
【００１２】 また、作業中の作業員は、送信側試験機２３や受信側試験機２４の近傍で作業 を行わなければならないため、他の作業（例えば、道具を取りに行く）を行うた めに離れる場合には、送信側通話機２３ａ、受信側通話機２４ａを外さなければ ならず、電話局（ＮＴＴビル）内の作業員とマンホール内の作業員とで連絡が取 れなくなってしまう。 さらに、上述したように、送信側通話機２３ａや受信側通話機２４ａが、送信 側試験機２３や受信側試験機２４装置にコードで接続されていると、作業員が通 信線の切り替え作業を行ううちに、該コードが他の接続線等に絡まり、作業を中 断しなければならないといった問題があった。In addition, since a worker who is working must perform work in the vicinity of the transmitting test machine 23 and the receiving test machine 24, he or she must perform other work (for example, go to get tools). If the user is away from the office, the sender's telephone 23a and the receiver's telephone 24a must be removed, so that workers in the telephone office (NTT Building) and workers in the manhole cannot communicate with each other. Further, as described above, if the transmitting side communication device 23a and the receiving side communication device 24a are connected to the transmitting side testing device 23 and the receiving side testing device 24 with a cord, the worker can perform the switching operation of the communication line. During the operation, there is a problem that the cord is entangled with other connection lines and the like, and the operation must be interrupted.

When the probe (pickup) comes into contact with or comes close to the selected specific communication line, a continuous sound is produced on the receiving side, and when the probe (pickup) comes into contact with or comes close to the other communication lines, an intermittent sound is produced on the receiving side. A means for transmitting these intermittent sounds and continuous sounds to the telephone call signal is provided, and furthermore, the receiving side telephone unit and the transmitting side telephone unit are codeless, so that the worker can confirm that the code to which the telephone unit is connected is another codec. An object of the present invention is to provide a line check device capable of performing a line check operation by discriminating a dial tone while having a conversation without being entangled in a code or restricting a work range.
