This is the DSL technology (Digital Subscriber Line).
The DSL technology comprises a set of modems at both ends of the pipe, which compress the data.
There are various types of DSL modems, being the most popu- lar currently the ADSL (Asymmetric Digital Subscriber Line).
Although this alternative is clearly inferior to the DSL proposed by telephone operators, it allows cable operators to reduce costs and risks, because the customer must undertake most of the investment.
Nevertheless, in spite of the fact that cable seems a better alternative than the DSL in offering high-speed, there are other points that should be con- sidered in weighting the advantages and disadvantages of the different technologies.
