本発明は局交換機と構内交換機とが局線路を介して接続
されてなる電話交換システムにおける着信局線の試験方
式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to a method for testing a terminating office line in a telephone switching system in which a central office exchange and a private branch exchange are connected via a central office line.
一般に、構内交換機（以下ＰＢＸとする）の着信局線番
号は代表番号制が大多数であり、複数の着信局線を有し
ていても発呼者は代表番号をダイヤルすることにより、
局交換機の代表サービス機能によって自動的に優先順位
の高い空の着信局線を選択して着信する。In general, most private branch exchanges (hereinafter referred to as PBXs) have a representative number system for the terminating station line number, and even if there are multiple terminating station lines, the caller can dial the representative number.
The central office exchange's representative service function automatically selects an empty receiving office line with a high priority and receives the call.
このような代表番号制を採用しているＰＢＸては、局交
換機２局線路、ＰＢＸ内の着信局線が重席であれば問題
はないか、例えば局線路か断線状態になったときを考え
ると、ＰＢＸ外の発呼者か該ＰＢＸの代表番号をダイヤ

出者」が聴こえ、あたかも重席に呼出中であるかの様な
可聴表示となるが、「呼出音」は線路断線のためにＰＢ
Ｘ側へは到達せず、ＰＢＸ例では着信表示がないと云う
現象が生しる。In a PBX that uses such a representative number system, if there are two central exchange lines and two incoming station lines within the PBX, is there a problem?For example, consider what would happen if the central office line was disconnected. When a caller from outside the PBX dials the main number of the PBX and receives a call to the disconnected terminating station line, the caller hears the "caller" and it appears as if the caller is calling someone else. However, the "ringing tone" is PB due to a line disconnection.
The call does not reach the X side, and in the PBX example, a phenomenon occurs in which there is no incoming call display.
特に、断線が最上位の優先度に割り当てられた着信局線
で発生した場合で該ＰＢＸへの着信が単発呼である場合
には、何回発呼しても応答なしの状態となる。また、優
先順位が低位の着信局線で断線した場合はその回線に着
信し７た呼のめは応答なしとなり、発呼者とＰＢＸの交
換手との間ζトラブルが発生する。Particularly, if a disconnection occurs in a terminating station line assigned the highest priority and the incoming call to the PBX is a single call, there will be no response no matter how many times the call is made. Furthermore, if a line at a receiving station with a low priority is disconnected, calls received on that line will not be answered, causing trouble between the caller and the PBX operator.
本発明はこのようなトラブルに対処するため、ＰＢＸ側
から局線発信し、自構内交換機の着信局線に着信するよ
うになし、ＰＢＸ側において「発呼信号」の到来の有無
を確認することによって着信局線の断線をチェックする
ものである。In order to deal with such troubles, the present invention transmits a call from the PBX side to the central office line, receives the call on the terminating line of the own private branch exchange, and checks whether or not a "calling signal" has arrived on the PBX side. This is to check for disconnections in the receiving station line.

有無を確認するものである。In other words, the P13X is equipped with an automatic dialing device (a distribution section that selectively switches the voice line to the terminating station line trunk and a ringing signal detection section), and the automatic dialing device
At the same time, the call is transmitted to the incoming station line of the BX so that the call is received sequentially, and the distribution unit is switched so that the incoming station line is sequentially connected to the paging signal detection unit, and the presence or absence of a paging signal is detected within the PBX. This is something to check.

=J, rill-1236J---. The clock device TIM shows the set time, for example, 22:00 (10:00 p.m.)
When this happens, a trigger signal is sent to the automatic dialing device AD. The automatic dialing device AD thereby sends out a dial pulse signal corresponding to the terminating station line number rlli1234i together with the station line originating number. In connection with this, the test line control unit C, ON T has a table that corresponds telephone numbers and distribution units, and refers to this table to determine the distribution unit N.

される。This paging signal is detected by the paging signal detection section DET via the distribution section N0.0 on the PBX IQO side. When a ringing signal is detected by DET, D
The ET sends a "presence" signal to the test line control unit C0NT. This “presence” signal restores the distribution unit 1100 and connects the distribution unit 111o, 111 to the calling signal detection unit D E 'T'' side.The automatic dialing device AD is controlled by the control unit AD. After releasing the path that sent the dial pulse train and re-calling, the station line originating number and rill-1235 corresponding to the next terminating station line are released.
Sends a J dial pulse train. This pulse train is sent to the central office exchange 200 using the same sending route as before, and is sent to the central office exchange 200 via the path (1

For this purpose, test line control unit C0N
Before switching each distribution section to the DET side, T uses a known technique to detect the busy state of the terminating station line trunk corresponding to the line number to be sent, and only when the trunk is empty, the distribution section is activated. The automatic dialing device is turned on and a dialing pulse train is sent out. In addition, distribution part No., O
