KFXO – 240HI / SPX

analog line recording board


The main function of KFXO-240HI Express board is passive, high impedancerecording of PBX branches or analogical telephone lines. It is connected, inparallel mode, to the telephone, recording in a way that is not perceived bythe users and without degrading the call audio. This board reports to the hostthe telephone line presence and every ring signal, polarity reversal, audioevents, answering, or end of call, without needing to integrate with the PBXfor starting or ending the recording process. For assuring reliability, theKFXO-240HI board starts and stops recording by detecting line tension,which varies with on-hook and off-hook events.
