Abstract: The present invention enables a traditional analog telephone to be used with VoIP applications. For example, the user could connect their standard 900 MHz telephone to this invention, establish a VoIP call and enjoy the freedom of movement their cordless telephone provides. The preferred embodiment of the present invention minimizes overhead to the host computer via a dual CODEC modem that incorporates a DSP capable of simultaneous communication with the two CODEC modules. This architecture facilitates a latency and communication overhead reduction as the analog voice signals effectively “stream” from the first CODEC to the second CODEC.

Abstract: An interlocking computer card device having computer module dimensions such as a PCMCIA type III architecture comprising two PCMCIA type II computer card devices. Each computer card device has a full wall extendable media connector and a substantially identical computer card housing. The full wall extendable media connector can be configured to couple with a media-plug facing different directions or it can be attached to an antenna for receiving wireless communications. The computer card housing has a bottom planar surface, a top planar surface, a connector housing that extends out of the top planar surface and a recess that has substantially the same shape as the connector housing. The computer card housing also has protrusions and dimples that are configured for coupling with corresponding dimples and protrusions of another computer card housing.

Abstract: The present invention is an adaptor module that allows an electrical connection to be established between a communication system and a communication card. Advantageously, the adaptor module can be configured to provide an interface between the communication card and various communication systems, such as conventional telephone systems, cellular telephone systems, digital telephone systems, local area networks (LANs), personal area networks (PANs), wireless systems, etc. Additionally, the adaptor module can provide an interface between a plurality of communication systems and the communication card. For example, the adaptor module may provide an interface for a plurality of connectors from the same type of communication system and/or the adaptor module may provide an interface for connectors from different types of communication systems. Advantageously, the adaptor module can provide simultaneous communication with these various communication systems.

Abstract: A telecommunications device for transmitting or receiving E-mail across telephone lines without requiring the use of a conventional computer or a service provider for access to an E-mail account is provided. In a preferred embodiment, at the transmission location, the telecommunications device receives a message at a communications port from a personal data assistant device by an infrared link. Thereafter, the message is coupled to a modem circuit for modulation over the telephone line. The E-mail is routed to a reception location according to a phone number and, upon arrival at the reception location, is routed to or answered by another telecommunications device by means of an identifier emplaced in the caller identification packet. Acknowledgment indicators are also provided to display a status of the message. In another preferred embodiment, the message is input directly into the telecommunications device by means of a graffiti screen integrated therein.

Abstract: A line powered data communication apparatus (DCA) includes dual programmed microcontrollers, one being interfaceable with data terminal equipment and the other for governing the operation of modem circuitry of the DCA which is interfaceable to a telephone line of a telephone network. The dual programmed microcontrollers interact with each other over an electrically isolated interface, preferably including optical isolators. Power is derived for the one microcontroller from the signal lines interfacing the data terminal equipment. In addition, power is derived for the other microcontroller and modcircuitry from the telephone line.
