Abstract: Phase correction device for a 2880 c/s carrier which is used for transporting the received band to the basic band (0 - 2400 c/s), the correction being based on characteristics relating to the form of the signal in the basic band.
Abstract translation: 用于将接收频带传送到基本频带（0-200c / s）的2880c / s载波的相位校正装置，该校正基于与基本频带中信号形式有关的特性。

Abstract: The local test system, for moderns (3) in a duplex telephone line, has a local converting oscillator (14) and a modulator (15) to convert the transmitter (1) frequency into another frequency band. The modulator output is connected to the receiver (2) input. An inverter (16) is connected to the receiver output. For a modern operating in the band 1,080Hz to 1,750 Hz, the local oscillator frequency is 2,830GZ and can be varied at least 200Hz about this centre frequency.
