在线路供电根据电话站，电容器并联连接到电压稳定的语音电路。 由于接收放大器是消费者在一个大大波动大的功率消耗，该电容器必须在尺寸比较大。 这导致切换的充电时间长，在此期间发送放大器（SV）和控制电路（SS）工作不足之后。 在本发明中，这个问题是由一个第二电容器（C2）避免被布置成平行于接收放大器（EV），第一电容器（C1）和平行于所述语音电路（SV，SS），这是相对于该第一电容器（C1）的其余部分更小的尺寸的 并接通第一电容器（C1）的充电完成之后第二电容器（C2）的充电时仅开始。 本发明适用于供电根据电话站的所有线。

In line powered According telephone station for voltage stabilization, a capacitor is connected in parallel to the voice circuit. Since the receiver amplifier is a consumer with a greatly fluctuating large power consumption, this capacitor must be dimensioned relatively large. This results after turning a long charging time during which the transmitter amplifier (SV) and the control circuit (SS) do not work sufficiently. In the invention, this problem is avoided by parallel to the receiving amplifier (EV), a first capacitor (C1) and parallel to the rest of the speech circuit (SV, SS), a second capacitor (C2) is arranged opposite to the first capacitor (C1) is smaller dimensioned is and after switching on the charging of the first capacitor (C1) only starts when the charging of the second capacitor (C2) is completed. The invention is in all line powered According telephone stations applicable (FIG. 1).
