2 Terminology

What is DOCSIS?

DOCSISŪ 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 "CableModemŪ" or "CableModem/DOCSISŪ".
