Patent ID: 7460522

Claim:
An apparatus, comprising: a converting unit receiving a voice signal and performing at least one selected from among analog to digital conversion and digital to analog conversion on the voice signal; a first processor receiving the voice signal from said converting unit, storing a plurality of procedures, the procedures conforming to predetermined standards of a plurality of voice communication modes, the plurality of voice communication modes including a selected mode, said first processor performing the stored procedure corresponding to the selected mode to cause the voice signal to comply with the predetermined standard corresponding to the selected mode, the selected mode being a mode selected from at least a voice over Internet protocol mode, a voice over digital subscriber line mode, and a voice, over multi-service broadband networks mode; a digital tone generating unit storing a plurality of sources of tones for phone functions, storing tones corresponding to the plurality of voice communication modes, generating at least one tone corresponding to the selected mode; a multiplexer receiving and multiplexing the at least one tone from said digital tone generating unit and the processed voice signal from said first processor, and outputting the multiplexed signal to said converting unit; a second processor confirming the selected mode and outputting information identifying the confirmed selected mode to said digital tone generating unit and to said first processor; a relay switch receiving an off signal from said second processor and interrupting a central office phone line when a predetermined code is selected, the predetermined code corresponding to the voice communication modes including digital network services, and maintaining an on state when a general central office phone digit is selected; a third processor being in communication with said second processor, supporting communication during transmission of asymmetric digital subscriber line data, said third processor removing generated noise; and an analog front end being in communication with said third processor, supporting matching of an asymmetric digital subscriber line, and enabling bi-directional dual communication of the asymmetric digital subscriber line data.
