    • PURPOSE:To count and display the message rate despite no detection of a reverse signal, by starting the counting of duration of call when a prescribed period elapses after the dial digits are detected. CONSTITUTION:A call given from a subscriber SUB is detected at a loop detecting part via a detecting circuit C, and then a dial digit detecting part DS is actuated. Then the dial is detected at the part DS and via the circuit C. A reverse detecting part RV is actuated after the final digit of the dial is detected, and a time counter TC is set. The counter TC actuates a call duration counting part T when 5 seconds, for example, have passed. If the reverse signal is detected before 5 seconds elapse, the counter TC is reset. At the same time, the part T is actuated.
    • 目的:即使没有检测到反向信号,也可以计数和显示消息速率,通过在检测到拨号数字后经过规定时间后,开始对呼叫持续时间的计数。 构成:通过检测电路C在环路检测部检测到从用户SUB发出的呼叫,然后致动拨号数字检测部分DS。 然后在部分DS和电路C处检测拨号盘。在检测到拨号盘的最后一位之后,启动反向检测部分RV,并设置时间计数器TC。 例如5秒钟时,计数器TC启动通话时间计数部分T。 如果在经过5秒钟之前检测到反向信号,则计数器TC被复位。 同时,部件T被致动。
