している。The communication base state identification method of the present invention includes a detection circuit that determines that data is disconnected based on an unused signal inputted from the communication base when the line is not in use, and outputs a sending command signal and an alarm signal; a display signal generating circuit that outputs a display signal indicating that the line is not in use when the unused signal and the sending command signal are input, and stops the display signal when an external control signal is input; , a monitoring device that displays a disconnection based on the data when only the alarm signal is input, and displays that the line is unused when the control signal and the alarm signal are input. There is.
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 explained with reference to the drawings.
第１図は本発明の一実施例のブロック図である。FIG. 1 is a block diagram of one embodiment of the present invention.

にデータが断の表示を行い、制御信号５とアラーム信号
２とが入力されたときは判断回路１１により回線が未使
用の表示を行う監視装置８とを有して構成される。This embodiment includes a disconnection detection circuit 7 that determines that data is disconnected based on an unused signal 1 that is input when the line is unused from the communication base, and outputs a sending command signal 3 and an alarm signal 2. When the use signal 1 and the sending command signal 3 are input, the AIS signal 4 that indicates that the line is not in use is output, and when the control signal 5 that prohibits sending the AIS signal from the outside is input, the AIS signal 4 is output. AIS generation circuit 6 that stops
and when only alarm signal 2 is input, monitor 10
It is configured to include a monitoring device 8 which displays that the data is disconnected when the data is disconnected, and displays by a judgment circuit 11 that the line is unused when the control signal 5 and the alarm signal 2 are input.
このようにすると、回線の未使用が入力されたとき断検
出回路７でデータが断であると判断すると、ＡＩＳ発生
回路へ送出命令を出方し、監視装置８へはアラーム信号
を出力し、送出命令を受けたＡＩＳ発生回路は、外部が
らＡＩＳ信号の送出を禁止する制御信号が設定されてい
るときは監視装置８へＡＩＳ信号を出方しないが監視装
置としては、回線が断であるというアラーム信号を断検
出回路７から受けていてもＡＩＳ信号が出力されていな
い場合には判断回路１１により回線が未使用であると判
断させることができる。In this way, when the disconnection detection circuit 7 determines that the data is disconnected when the unused line is input, it issues a sending command to the AIS generation circuit, outputs an alarm signal to the monitoring device 8, The AIS generation circuit that receives the transmission command does not output the AIS signal to the monitoring device 8 when a control signal for prohibiting the transmission of AIS signals is set from the outside, but the monitoring device recognizes that the line is disconnected. If the AIS signal is not output even if an alarm signal is received from the disconnection detection circuit 7, the determination circuit 11 can determine that the line is unused.
以上説明したように本発明は、ＡＩＳ信号の送出を禁止
する制御信号とアラーム信号とで回線未使用の表示を行

ことにより、通話路盤の状態を誤りなく表示できるとい
う効果がある６As explained above, the present invention uses a control signal that prohibits the sending of an AIS signal and an alarm signal to indicate that the line is not in use, and displays a data disconnection when only the alarm signal is input, thereby controlling the condition of the communication base. It has the effect of being able to display without error6
