Embodiment Construction
[0038] refer to figure 1 , gives a schematic diagram of the main hardware components of the modem device 1 of the present invention. This hardware architecture forms the link between the telephone line and one or more computers. The telephone line interface 3 is usually a DSL terminal interface using an RJ-11 connector.
[0039] The ADSL modem device 1 also includes a first module 2, the first module 2 contains an analog front end and an application specific integrated circuit (ASIC), which is used to terminate the analog line interface, and convert the digital data from the main controller 4 into an analog bandpass signal, ASIC will be called ADSL ASIC. The analog front-end module consists of a high-pass filter, which filters out Plain Old Telephone Service (POTS) signals and allows ADSL signals to pass through; a hybrid circuit, such as a passive network, which performs 2-wire to 4-wire conversion, or vice commutation for splitting between upstream and downstream signals;...
