DOCSIS is an acronym for "Data Over Cable Service Interface Specification".
DOCSIS provides a set of standards and a certifying authority by which cable companies can achieve cross-platform functionality in Internet delivery. DOCSIS standards are applied to both ends of the connection: the CM (Cable Modem) and the CMTS (Cable Modem Termination System).
The standards are set and verified by CableLabs
, a non-profit industry consortium. CableLabs also refers to the DOCSIS specification "CableModem" or "CableModem/DOCSIS".
