Data Over Cable Service Interface Specification DOCSIS® 1.0 The first version of the Data Over Cable Service Interface Specification. DOCSIS 1.0 defines requirements for cable modems and cable modem termination systems that enable broadband Internet access. The (ITU-T) has approved the various versions of DOCSIS® as international standards. DOCSIS® 1.0 was ratified as ITU-T Recommendation J.112 Annex B (1998). DOCSIS® 1.1 The second version of the DOCSIS protocol specification. DOCSIS 1.1 includes an enhanced Media Access Control (MAC)-layer that contains quality of service (QoS) traffic management functions as well as cable modem authentication extensions. Also known as “one-one”. The (ITU-T) has approved the various versions of DOCSIS® as international standards. DOCSIS® 1.1 was ratified as ITU-T Recommendation Annex B (2001). DOCSIS® 2.0 The third version of the DOCSIS protocol specification, developed to significantly increase the upstream data carrying capacity and the robustness to noise and interference. DOCSIS® 2.0 includes advanced TDMA and S-CDMA physical layer technologies. The (ITU-T) has approved the various versions of DOCSIS® as international standards. DOCSIS® 2.0 was ratified as ITU-T Recommendation . DOCSIS® 2.0 + IPv6 The “DOCSIS® 2.0 + IPv6” standard (revision 3 published 10 February 2011) supports IPv6, which may require a DOCSIS® 2.0 equipment firmware upgrade on the customer premises equipment (CPE) (cable modem (CM)) side of DOCSIS® enabled networks. DOCSIS® 3.0 DOCSIS® 3.0 features management over and , which enables multiple downstream and upstream channels to be used together at the same time by a single subscriber. Common DOCSIS® 3.0 speeds are listed in the table below.
