    • A cordless communication device is provided in which a processor used to code and decode signals for the wireless communication is further used to process messages for an integral answering machine. An existing digital signal processor (DSP) within the cordless phone is used to code and decode signal for wireless communication between the base station and the handset. The coding scheme used for the wireless communication, for example, adaptive differential pulse code modulation (ADPCM), is also used for compressing, storing and retrieving messages used in the answering machine.
    • 提供了一种无绳通信设备,其中用于对用于无线通信的信号进行编码和解码的处理器进一步用于处理用于集成应答机的消息。 无线电话内的现有数字信号处理器(DSP)用于对基站和手机之间的无线通信的信号进行编码和解码。 用于无线通信的编码方案,例如自适应差分脉码调制(ADPCM)也用于压缩,存储和检索在应答机中使用的消息。
