    Abstract: The present invention facilitates communications between a first network and a second network using an information routing device having an auto-configuration feature. The auto-configuration feature negotiates what authentication protocol will be used when the networks transfer information. Once the authentication protocol is negotiated by the device, the device intercepts and stores information transferred between networks. In this manner, the device can emulate a first network when coupled to a second network by providing the necessary stored information directly to the second network, and vice versa.

    Abstract: Apparatus and methods are provided for selectively providing telephone service that is either PSTN-based or Internet-based using a standard analog telephone circuit. In a first embodiment, the apparatus comprises a hardware module and associated software for coupling a personal computer or Internet appliance and a standard analog telephone. The apparatus includes a DTMF interface circuit, a subscriber line interface circuit, a ring detection circuit, and an interface circuit for interfacing with the PC or Internet appliance. The apparatus permits the analog telephone to be toggled between an Internet-based telephone mode and a PSTN-network mode by inputting a predetermined sequence of DTMF digits. In alternative embodiments, the apparatus comprises a processor, modem and optionally, analog telephone circuit, to provide a stand-alone or partially-integrated device capable of selectively switching between PSTN-based and Internet-based telephony services.

    Abstract: A circuit for modulating an N-phase first waveform having a frequency F.sub.O with an N-phase second waveform having a frequency F.sub.M. The circuit includes N number of limited swing driver circuits. Each limited swing driver circuit has generator means for generating one phase of a third waveform in response to one phase of the first waveform so that the third waveform has a frequency F.sub.O and a voltage swing that is less than a voltage swing of the first waveform. The circuit also includes N number of multiplier circuits. Each multiplier circuit is coupled to one of the limited swing driver circuits and has multiply means for multiplying one phase of the third waveform with one phase of the second waveform and for generating first and second currents having a difference which is proportional to a product of the one phase of the third waveform and the one phase of the second waveform. A load circuit is coupled to the multiplier circuits and has a first node into which the first currents generated by each of the multiplier circuits are summed together to form a first summation current and a second node into which the second currents generated by each of the multiplier circuits are summed together to form a second summation current. The load circuit has a comparing stage for comparing which of the first and second summation currents is larger and for generating a first clock signal having a frequency approximately equal to a frequency of a change in magnitude of the first and second summation currents. A method of modulating an N-phase first waveform having a frequency F.sub.O with an N-phase second waveform having a frequency F.sub.M is also disclosed.
