DOCSIS (Data Over Cable Service Interface Specification) refers to a series of technical specifications for enabling high-speed data transfer over existing coaxial cable television infrastructure. It is a global standard developed and maintained by CableLabs. The primary goal of DOCSIS is to allow cable operators to deliver internet access to their subscribers efficiently. Different versions of DOCSIS have been released over time, each introducing significant improvements in speed, efficiency, and capacity. These versions include DOCSIS 1.0, 1.1, 2.0, 3.0, 3.1, and the upcoming 4.0. Key advancements include the use of channel bonding, which allows multiple channels to be combined for increased bandwidth, and more efficient modulation schemes. DOCSIS operates by using specific frequency channels within the cable spectrum to transmit data, separating it from the video signals. A DOCSIS-compliant modem, also known as a Cable Modem (CM), connects to the coaxial cable network and communicates with a Cable Modem Termination System (CMTS) located at the cable operator's headend. This two-way communication enables internet connectivity for users. The evolution of DOCSIS has been crucial in meeting the growing demand for bandwidth for applications such as streaming video, online gaming, and cloud computing.
