CDSL

CDSL is a broadband transmission technology based on Digital Subscriber Line (DSL) technology.

What is CDSL (in computer networking)?

Stands for Consumer DSL, a broadband transmission technology based on Digital Subscriber Line (DSL) technology. CDSL was developed by Rockwell and is a slower technology than the more common DSL variant called Asymmetric Digital Subscriber Line (ADSL).

CDSL provides data rates of about 1 Mbps downstream (about 128 Kbps upstream) to the customer premises over standard Plain Old Telephone Service (POTS) local loop wiring.

However, CDSL has the advantage of not requiring installation of a splitter at the customer premises. CDSL can operate only at distances of up to 18,000 feet from the telco’s central office (CO).
