NRJ Design Glossary


A digital subscriber line, or DSL, is a communications technology that allows data to travel at very high speeds over standard telephone wire without interrupting normal telephone service. The primary market for DSL is the home office since the technology makes it easy for residential homes to receive high-speed Internet access at a reasonable price. DSL speeds, on the average, run at about 600kbps for downstream and 128kbps for upstream.
