Abstract
A sound codec has an encoded signal input/output terminal. This terminal is selectively connected to a modem codec. Due to this selective connection, a microphone and a speaker, both connected to a sound signal input/output terminal of the sound codec, are used as a transceiver of the speaker phone, and the sound codec is controlled to function as a speaker phone codec.
