Cable operators use docsis to provide internet access over their existing cable infrastructure for both residential and business customers docsis mini-pim interface overview data over cable service interface specifications (docsis) define the communications and operation support interface requirements for a data-over-cable system. Cable modems based on data-over-cable service interface specifications (docsis®) are among the fundamental devices making this transition possible normative source files also available docsis 30, 31, and mhav2 mibs. Data over cable service interface specification (docsis / ˈ d ɒ k s ɪ s /) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable tv (catv) system. For data over cable services between a cable modem and the customer premise equipment (cpe) the cpe may include pcs, macintoshes, workstations, network computers, and other electronic equipment.
The cable modem translate cable data into ethernet packets which are directed into a computer to a router for distribution in a small network outgoing transmissions will travel through a coax cable to a fiber node where it is then converted into light waves via an optical-electrical converter in order to travel over the fiber optic cable to. Cm-sp-ossiv3-i05-071206 data-over-cable service interface specifications 2 cablelabs 12/06/07 document status sheet document control number: cm-sp-ossiv3-i05-071206. Most isps make it difficult to use a modem other than their own by using docsis (data over cable service interface specification) standards to send information to your modem other isps use cable or dsl (digital subscriber line) modems to connect your home/office to the internet network. It is up to current docsis (data over cable service interface specification) 30 standards and is backwards compatible with docsis 20 and 11 services features because the modems we tested all met our expectations and performed up to their advertised capacities, ease-of-use and other features weighed heavily on our rankings. Data over cable service interface specification, or docsis, is an international telecommunications standard that allows for the addition of high-bandwidth data transfer to an existing coaxial cable tv system.
Without a return path, the old docsis 10 standard still allows use of data over cable system, by implementing the return path over regular phone lines, eg plain old telephone service (pots) if the hfc is already 'two-way' or interactive, chances are high that docsis 11 or higher can be implemented.
