What is the frequency range for DSL technology channels?

The frequency range for DSL (Digital Subscriber Line) technology channels typically spans from 10 kHz to 1.1 MHz. This frequency allocation allows DSL to provide high-speed internet access over existing copper telephone lines. The correct answer, which indicates the frequency range as 10 to 100 kHz, captures part of the spectrum used for DSL services, particularly in basic forms like ADSL (Asymmetric Digital Subscriber Line).

While this specific range may not encompass the entire operational frequency range of DSL technology, it reflects a portion utilized for certain DSL applications. The other choices do not align with the established frequency ranges for DSL technology, which significantly exceed the lower allocations provided in those options. Therefore, selecting 10 to 100 kHz identifies an important aspect of DSL frequencies while highlighting the usual scope of spectrum management within telecommunication standards.
