    • A method and apparatus for providing control and monitoring of a group of plain old telephone service (POTS) stations from one control station. Incoming calls to the POTS stations are intercepted and the data describing the call is sent to the control station. The control station then provides directions for blocking the call, completing the call to the original POTS destination, or completing the call to another POTS destination. Outgoing calls are also monitored so that the control station maintains an up to date record of which stations are busy and which stations are idle. Advantageously, the control station communicates with the switch serving these POTS stations by analog signals (FSK) and/or DTMF thus overcoming the limitations on distance requirements for digital signaling.
    • 一种用于从一个控制站提供对一组普通老式电话服务(POTS)站的控制和监视的方法和装置。 拦截对POTS站的来电,并将描述呼叫的数据发送到控制站。 然后,控制站提供阻止呼叫,完成对原始POTS目的地的呼叫或完成对另一个POTS目的地的呼叫的指示。 还监视拨出呼叫,使得控制站保持哪些站正在忙碌以及哪些站是空闲的最新记录。 有利地,控制站通过模拟信号(FSK)和/或DTMF与服务于这些POTS站的交换机进行通信,从而克服了对数字信令的距离要求的限制。
