DSL
Digital Subscriber Line

DSL describes a physical layer technology that can be utilized across the last mile connectivity between a customer’s premises and the Local Exchange or Central Office. Typically based on a copper twisted pair transmission medium, DSL can come in a variety of formats. A particular example of this is ADSL2+ , which employs techniques such as DMT between the ATU-R (ADSL Termination Unit – Remote) and the DSLAM.
