  • Patent number: 7386104
    Abstract: Systems and methods are described for providing connectivity to portable electronic devices, such as a cordless telephone, for the purpose of upgrading software features. In a preferred embodiment, portable electronic devices can receive incoming data at the PSTN jack from a personal computer that is also connected to the PSTN via a PSTN modem. In this manner, upgrades can be accomplished without requiring users to disconnect the telephone or to connect additional cables or components. The telephone is temporarily disabled from service only during the downloading of the upgrade software from the personal computer to the telephone.

  • Patent number: 7386304
    Abstract: Systems and methods are described for providing connectivity to portable electronic devices, such as a cordless telephone, for the purpose of upgrading software features. In a preferred embodiment, portable electronic devices can be connected to a conventional household audio player via an audio input/out interface in the device to receive encoded data signals modulated in an audio band. The audio player can playback an audio signal stored in any of several different formats, including compact disc, audio cassette tape, MP3 file, or streaming audio, and can be physically connected an audio jack in the portable electronic device via a conventional audio cable. The device demodulates and decodes the signal and routes the transmitted data to memory registers for upgrading software stored in device memory.
