Explanation
DOCSIS (Data Over Cable Service Interface Specification) is the standard protocol used by cable-based ISPs to deliver internet over coaxial cable infrastructure. To connect that coaxial cable signal to a standard Ethernet-based LAN, a cable modem is required. The cable modem converts the DOCSIS signal from the ISP into a format usable by devices on a home or small office network. While routers, switches, and access points are also common in SOHO environments, they cannot translate the DOCSIS signal - only a cable modem sits at that specific interface between the ISP's cable plant and the local network.
