What is DOCSIS?
Data Over Cable Service Interface Specifications. DOCSIS defines interface
requirements for cable modems involved in high-speed data distribution over a cable
television network. On November 17, 1997, Cable Television Laboratories, Inc. (Cable
Labs) and its members established a formal path of certification for cable modem
equipment suppliers to obtain an interoperability seal for their products based on the
DOCSIS specification. This certification process provides cable modem equipment
suppliers with a fast, market-oriented method for attaining cable industry
acknowledgment of compliance with DOCSIS.
The seal is meant to provide the purchaser with a way to be confident that the modem
equipment to be purchased is compliant with the specification, and that the equipment
interoperates with DOCSIS products made by other vendors.
