A method, comprising:

• performing an operation for hook-on;
• detecting at least a first selected digit;
• when the first selected digit corresponds to a general central office phone number, performing a general telephone call through a general telephone line;
• when the first selected digit corresponds to a predetermined code, switching a relay on the general phone line, the predetermined code corresponding to digital network services;
• when said switching is performed, detecting a second selected digit selected after the first selected digit, the second selected digit corresponding to selected digital network services selected from among a plurality of digital network services, the plurality of digital network services including at least a voice over Internet protocol service, a voice over digital subscriber line service, and a voice over multi-service broadband networks service;
• when the second selected digit corresponds to the voice over Internet protocol service, loading voice over Internet protocol firmware and making a voice over Internet protocol call;
• when the second selected digit corresponds to the voice over digital subscriber line service, loading voice over digital subscriber line firmware and making a voice over digital subscriber line call;
• and
• when the second selected digit corresponds to the voice over multi-service broadband networks service, loading voice over multi-service broadband networks firmware and making a voice over multi-service broadband networks call.

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 a voice signal from said converting unit when digital network services are selected, said first processor storing a plurality of procedures according 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 causing the voice signal to comply with the predetermined standard corresponding to the selected mode when the digital network services are selected;
• a digital tone generating unit generating at least one tone corresponding to the selected mode and outputting the at least one tone to said converting unit;
• a second processor confirming the selected mode and outputting information identifying the confinned selected mode to said digital tone generating unit and to said first processor,
• a relay receiving an off signal from said second processor and turning off to interrupt 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 at least one general central office phone digit is selected, the predetermined code being distinguishable from the at least one general central office phone digit;
• a third processor being in communication with said second processor, supporting communication during transmission of asynunetric 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.
