DSL - Asymmetric Digital Subscriber Line (ADSL)

Asymmetric Digital Subscriber Line (ADSL) is an umbrella term that refers to a series of xDSL technologies that deliver broadband connectivity to the business or the residence over a single copper pair. The term asymmetric refers to the fact that download speeds are typically much higher than upload speeds.

There are several versions that deliver different speeds:

  • ADSL - up to 10 Mbps download and 1 Mbps upload
  • ADSL2 - up to 12 Mbps download and 3.5 Mbps upload
  • ADSL2+ - up to 24 Mbps download and 3.5 Mbps upload
