xDSL (various forms of DSL)

xDSL refers to a family of high-speed internet technologies that transmit digital data over traditional telephone lines. Different types, like ADSL (Asymmetric), SDSL (Symmetric), and VDSL (Very-high-bit-rate), vary mainly in speed and how they allocate bandwidth. For example, ADSL provides faster download speeds ideal for most users, while SDSL offers equal upload and download speeds suitable for business needs. These technologies allow households and businesses to access fast internet without installing new cabling, making use of existing phone lines. Despite sharing the same basic infrastructure, each type is optimized for different uses and performance requirements.
