ーム表示を出す制御手段とを備えている。The line disconnection failure detection method of the present invention includes a call state detection storage unit that stores extension information and trunk information when a call is made by connecting an extension and a trunk, and a line disconnection during a call corresponding to the trunk. A line disconnection number storage means for storing the number of times of occurrence, and an alarm display when the count value reaches a preset value by counting up the line disconnection number storage means by a notification signal from an extension that has encountered a line disconnection during a call. And a control means for outputting.
次に本発明について図面を参照して説明する。 Next, the present invention will be described with reference to the drawings.

（以下PRT）８とを備える。Referring to FIG. 1, a private branch exchange is a telephone line switch (hereinafter SW) 2 for accommodating an extension 1, a trunk (TRK) 3 and an S.
A transmission register (hereinafter OR) 4 connected to W2, a central control unit (hereinafter CC) 5 that controls sequence control in the exchange,
A call state memory (hereinafter, MA) 6, a line disconnection number memory (hereinafter, MB) 7, and a printer (hereinafter, PRT) 8 for alarm display of a faulty trunk are provided.

ランク番号をTRK＃１とする。As shown in FIG. 2, MA6 stores the TRK number making the call and the accommodation position information (hereinafter LEN) on SW2 of the extension for each call number # 1, # 2, to #n, and MB7 Stores the number of line disconnections for each TRK number # 1, # 2, to #m as shown in FIG. The LEN of extension 1 is LEN 1 and the trunk number of TRK3 is TRK # 1.
続いて本実施例の動作について説明する。Next, the operation of this embodiment will be described.

回線断回数を＋１する。CC5 is MA6 when extension 1 is connected to TRK3 via SW2
TRK e.g. call # 1 area # 1 and stores the LEN 1. In this state, if the line connected to TRK3 becomes faulty while extension 1 and TRK3 are talking, CC5 will detect the line disconnection from TRK3 being monitored and extension 1 will hook (that is, extension line). When 1 goes on-hook once and then goes off-hook again, control SW2 and connect extension 1 to OR4. When extension 1 hears the dial tone from OR4 and dials the specified special number, CC5 reads LEN 1 and TRK # 1 from the call # 1 area of MA6, and the number of disconnections in the TRK # 1 area of MB7. Increment by 1.

ラームメッセージを送りプリントアウトさせる。Next, CC5 is connected to the line of TRK3 during a call, and the MAV is received each time the special number dial signal is received from the extension of the other party of the call.
The information read from 6 counts up the number of line disconnections in the TRK # 1 area of MB7. When CC5 confirms that the number of times of disconnection has reached a preset number (for example, 5 times), CC5 sends an alarm message such as "there are several disconnections in TRK # 1" to print out.
なお、MB7の記憶内容は毎日TRK不使用時の定時刻に０ク
リアするようにしてもよい。The stored contents of MB7 may be cleared to 0 at a fixed time every day when TRK is not used.
以上説明したように本発明は、通話中に回線断を起こし
