Abstract
A first device receives and processes signals from a communication link that supports a plurality of signal protocols. The device comprises a converter, coupled to the communication link, that outputs a sampled data stream, and a digital filter that filters the sampled data stream to separate signals associated with different signal protocols. A second device receives a first input sampled data stream representative of a first signal to be transmitted and associated with a first signal protocol and a second input sampled data stream representative of a second signal to be transmitted and associated with a second signal protocol, and combines the data streams into an output data stream which may be coupled to the communication link.
Claims35
A device that receives and processes signals from a telephone line and supports a plurality of telephone signal protocols, comprising:
- a converter circuit that digitizes input signals received on the telephone line;
- and
- a digital filter circuit that filters the digitized input signals to separate signals associated with different protocols.
A telephony device that receives signals from and transmits signals to a telephone line, the device comprising:
- a single data transmit, data receipt, analog signal path, coupled to the telephone line;
- wherein the device supports multiple different telephone signal protocols through the single data transmit, data receipt, analog signal path.
A telephony device that processes signals received on a telephone line for supporting multiple different telephone line signal protocols, the device comprising:
- a digitizer, coupled to the telephone line, that digitizes at least two of the multiple input signals received on the telephone line.
A device that receives and processes signals from a communication link and supports a plurality of signal protocols, comprising:
- a digital filter that receives a single sampled data stream;
- wherein the device supports the at least two of the plurality of signal protocols through the digital filter.
A device that processes signals received on a communication link for supporting a plurality of signal protocols, the device comprising:
- a digital filter, coupled to the communication link, that receives a single sampled data stream, and outputs at least two separate sampled data streams each having an association with a respective one of at least two of the plurality of signal protocols.
A device that receives and processes signals from a communication link and supports a plurality of signal protocols, comprising:
- a converter, coupled to the communication link to receive a single analog input signal;
- wherein the device supports at least two of the plurality of signal protocols through the converter.
A device that processes signals received on a communication link for supporting a plurality of signal protocols, the device comprising:
- a converter, coupled to the communication link, that outputs a single sampled data stream that is representative of at least two components each having an association with a respective one of at least two of the plurality of signal protocols.
A device that receives and processes signals from a communication link and supports a plurality of signal protocols, comprising:
- a converter, coupled to the communication link, that receives an analog input signal indicative of a signal on the communication link and outputs a sampled data stream representative of the analog input signal;
- and
- a digital filter that receives the digital signal and outputs at least two separate digital signals each having an association with a respective one of at least two of the plurality of signal protocols.
A device that receives and processes signals from a communication link that supports a plurality of signal protocols, comprising:
- a converter, coupled to the communication link, that outputs a sampled data stream;
- and
- a digital filter that filters the sampled data stream to separate signals associated with different signal protocols.
A device that receives a first input sampled data stream and a second input sampled data stream, the first input sampled data stream being representative of a signal associated with a first signal protocol, the second input sampled data stream being representative of a signal associated with a second signal protocol, and generates an output data stream in response at least to the first input sampled data stream and the second input data stream.
