Abstract
The present invention is directed to preventing the generation of a jarring noise when a voice/data multiplexing modem is in a diverging condition. This is accomplished by the modem including an encoder section where a voice signal encoded by mapping it to 63 codes out of the 64 codes that can be expressed with 6 bits. When the unused code is detected by a detector section the reproduced voice signal is masked.
