ABSTRACT:
A fault detecting system is provided for detecting fault of an ADPCM codec for transcoding an input signal between an ADPCM and a PCM to produce a first code converted signal. The ADPCM codec has a data RAM for storing data used for the transcoding and is provided with a data transmitter for transmitting the data. A fault detecting processor receives the data and generates a second code conversion signal from the received data. The fault detecting processor compares the first and the second code converted signals and produces a fault signal when both of the signals are not coincident with each other. The input signal can be supplied to the fault detecting processor directly or as a part of the data transmitted thereto. The fault detecting processor can detect fault of a plurality of ADPCM codecs by a time division fashion. The ADPCM codec and the fault detecting processor may be implemented as similar LSI processors each comprising a transcoding section, a data transmitting/receiving section, and a comparing section.
