Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial application]

この考案は、電話交換機、特にその保留モード継続時間の制限手段を備えた電 話交換機に関するものである。 The present invention relates to a telephone switchboard, and more particularly to a telephone switchboard having means for limiting the duration of its hold mode.

【0002】[0002]

【従来の技術】[Prior Art]

従来、PBX(構内交換)電話機もしくは、ホームテレホン等の保留回路は、 使用者による保留操作が検知されると、保留モードを設定し、この保留状態が所 定時間以上継続すると保留警報音を送出するよう構成され、その保留モード解除 は、あくまでも使用者のその後の操作により行われるよう構成されていた。 Conventionally, a hold circuit such as a PBX (Private Branch Exchange) telephone or a home telephone sets a hold mode when a hold operation by a user is detected, and outputs a hold alarm sound when this hold state continues for a predetermined time or longer. The hold mode is released by the user's subsequent operation.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、実際においては、前記保留時間が長くなると、使用者は前に保 留したことを忘れてしまうことが往々にしてあり、またこのことは保留警報が送 出されても解決されない時がある。このように保留時間が不必要に継続すると、 その間子機よりの外線発信は不能となり、また外線に重要な電話がかかっても“ 話中”と処理されてしまうという問題間があった。この対策方法の一例として、 例えば特開平2−7757号公報に保留自動解除機能付きの電話交換機が開示さ れているが、この考案は、より簡単な解決方法として、このような場合に保留警 報音の送出時間を制限し、次いで、保留解除を行うことにより、保留モードの所 定時間以上の長時間化を防止する手段の提供を目的としている。 However, in practice, the longer the hold time, the user often forgets that he was previously held, and this may not be resolved when the hold alert is sent. .. If the hold time continues unnecessarily in this way, there is a problem that outside calls from the handset will be disabled during that time, and even if an important call is made to the outside line, it will be processed as "busy". As an example of this countermeasure method, for example, Japanese Patent Application Laid-Open No. 2-7757 discloses a telephone exchange with an automatic hold release function. However, the present invention provides a simpler solution in such cases. It is an object of the present invention to provide a means for preventing the holding mode from becoming longer than a predetermined time by limiting the sending time of the alarm sound and then releasing the holding mode.

【0004】[0004]

【課題を解決するための手段】[Means for Solving the Problems]

このため、この考案においては、一本の外線に対して複数の内線の外線交換機 能を有する電話交換機において、前記外線の保留モードが所定時間継続すると保 留警報音を所定時間送出したのち、前記保留モードを解除するための解除手段を 備えるよう構成することにより前記目的を達成しようとするものである。 Therefore, in the present invention, in a telephone exchange having an outside line exchange function for a plurality of extension lines with respect to one outside line, after a holding alarm sound is sent out for a predetermined time when the outside line hold mode continues for a predetermined time, The object of the present invention is to be achieved by providing a releasing means for releasing the hold mode.

【0005】[0005]

【作用】[Action]

以上のような保留モード解除手段により、不必要な所定時間以上の保留状態の 長時間かが防止される。 The holding mode releasing means as described above prevents the holding state from being unnecessarily long for a predetermined time or longer.

【0006】[0006]

【実施例】【Example】

以下に、この考案を実施例に基づいて説明する。図1にこの考案を実施した電 話交換機の一例の概要構成ブロック図を示す。 (構成) 図1において、20は、従来例と同様の基本構成を有する電話交換機で、1は 、一本の外線(局線)13からの着信検出回路、2は、この着信をスイッチSW を介して行うための保留回路、3はDTMFレシーバ、4は、複数のドアホン1 5用のドアホン回路、5は内線電流供給回路、6は内線回路、7は通話検出回路 、8は呼出し信号発生回路、9はスピーカアンプ回路、10はクロスポイント切 換回路、11は制御回路、12は電源回路である。また、21はセキュリティ電 話機、22は複数のスピーカ付モジュラ、23は複数(1個のみを示す)の内線 電話機、24は留守番電話機、25はファクシミリを示す。 The present invention will be described below based on embodiments. FIG. 1 shows a schematic block diagram of an example of a telephone exchange in which the present invention is implemented. (Structure) In FIG. 1, 20 is a telephone exchange having the same basic structure as the conventional example, 1 is an incoming call detection circuit from one outside line (station line) 13, and 2 is a switch SW for receiving this incoming call. Holding circuit for performing the communication via DTMF receiver, 4 a doorphone circuit for a plurality of doorphones 15, 5 an extension current supply circuit, 6 an extension circuit, 7 a call detection circuit, 8 a call signal generation circuit Reference numeral 9 is a speaker amplifier circuit, 10 is a crosspoint switching circuit, 11 is a control circuit, and 12 is a power supply circuit. Further, 21 is a security telephone, 22 is a plurality of modular units with speakers, 23 is a plurality (only one is shown) of extension telephones, 24 is an answering machine, and 25 is a facsimile.

【0007】 ここにおいて、この実施例の特徴は、保留回路2内に、保留操作の開始と同時 にカウントを開始するタイマ(不図示)を配設し、このタイマのオンから所定小 時間t1 経過後、またはオンフックにより保留メロディを送出させ、さらにタイ マの所定時間t2 経過後この保留メロディの送出を中止して保留警報音に切換え 、さらにそれより所定時間t3 経過後、保留警報音の送出を中止すると共に、不 図示のリレーによりこの保留を解除して捕捉外線を開放するよう構成したもので ある。Here, the feature of this embodiment is that a timer (not shown) that starts counting at the same time as the start of the hold operation is provided in the hold circuit 2, and a predetermined small time t 1 has elapsed since the timer was turned on. After a lapse of time or on-hook, a hold melody is sent out, and after a predetermined time t 2 of the timer has elapsed, the sending of this hold melody is stopped and a hold alarm sound is switched to, and after a predetermined time t 3 has elapsed, a hold alarm sound It is configured such that the transmission of the signal is stopped and the holding line is released by releasing this hold by a relay (not shown).

【0008】 (動作) 図2に以上の構成における保留解除シーケンスのフローチャートを示す。ステ ップS1において使用者が外線着信に対して保留操作(フッキング)を行うと同 時にタイマがオンし、ステップS2でタイマの所定の小時間t1 (例えば20秒 )経過後、またはオンフックにより保留モードを設定し、ステップS3でスピー カ付モジュラ22より保留メロディを送出する。次にステップS4において、タ イマが所定時間t2 (例えば4分30秒経過すると、ステップS5で保留メロデ ィの送出を中止し、代わって保留警報音(例えば500/600Hzの10Hz 変調音)を送出し、ステップS6でこれがt3 時間(例えば30秒)経過すると 、ステップS7でこの保留警報音の送出を停止すると同時に不図示のリレーを用 いて保留モードを解除し、捕捉外線13を開放して動作を終了する。(Operation) FIG. 2 shows a flowchart of the hold release sequence in the above configuration. In step S1, when the user performs a holding operation (hooking) for an incoming call from an outside line, the timer is turned on at the same time, and in step S2, after a predetermined small time t 1 (for example, 20 seconds) of the timer has elapsed, or by an on-hook. The hold mode is set, and the hold melody is sent from the modular unit with speaker 22 in step S3. Next, in step S4, when the timer has passed a predetermined time t 2 (for example, 4 minutes and 30 seconds), in step S5 the sending of the hold melody is stopped and a hold alarm sound (for example, 10 Hz modulated sound of 500/600 Hz) is issued instead. When the time t 3 has elapsed (for example, 30 seconds) in step S6, the sending of the hold alarm sound is stopped in step S7, and at the same time, the hold mode is released by using a relay (not shown) to open the capture line 13. To end the operation.

【0009】 なお、以上の実施例は、内線の相互通信、ドアホン通信等の内線交換機能を有 する主装置の事例について説明したが、内外線交換機能は、これのみの場合に限 定されないことはもちろんである。また各所定時間の設定に関しても同様である 。In the above embodiment, the case of the main device having the extension exchange function such as extension mutual communication and intercom communication is explained, but the extension exchange function is not limited to this case. Of course. The same applies to the setting of each predetermined time.

【0010】[0010]

【考案の効果】[Effect of the device]

以上、説明したように、この考案によれば、保留モードの設定を使用者が忘れ てしまうことを防止するため、所定時間の保留警報音送出後、この保留モードを 解除して捕捉外線を開放するよう構成したため、不必要な保留状態の長時間化が 防止される。 As described above, according to the present invention, in order to prevent the user from forgetting the setting of the hold mode, after releasing the hold alarm sound for a predetermined time, the hold mode is released to open the outside line for capture. As a result, unnecessary holding time is prevented from being prolonged.
