Which statement best describes a key function of DOCSIS?

• A. It enables data transmission over cable
• B. It defines the video compression standard
• C. It specifies the wireless protocol
• D. It governs fiber deployment

Answer: (A)

DOCSIS is the standard that makes data travel over cable networks. It defines how data is modulated, framed, and multiplexed onto the existing coaxial cables, and how customer devices (cable modems) communicate with the network’s headend equipment (CMTS). This framework enables broadband Internet and other data services to run over the same cable TV infrastructure people already use. It isn’t concerned with video compression codecs, wireless communication protocols, or the deployment of fiber optics, so those areas lie outside what DOCSIS specifies. In short, its main function is to enable data transmission over cable.
