Data Over Cable Service Interface Specification

The Data Over Cable Service Interface Specification (DOCSIS) is a standard that allows high-speed internet to be delivered over cable TV networks. It defines how data is transmitted between your home modem and the cable provider’s network, ensuring reliable and consistent internet service. DOCSIS manages data encoding, error correction, and bandwidth sharing, enabling multiple users to access fast internet through existing cable infrastructure. It’s essentially the technology that allows cable companies to provide internet service alongside traditional TV, ensuring compatibility and performance across various equipment and networks.
