Editing DOCSIS (section)

==International standards==
The [[ITU Telecommunication Standardization Sector]] (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 DOCSIS 1.0 was ratified as ITU-T Recommendation J.112 Annex B (1998), but it was superseded by DOCSIS 1.1 which was ratified as ITU-T Recommendation [http://www.itu.int/rec/T-REC-J.112/en J.112] Annex B (2001). Subsequently, DOCSIS 2.0 was ratified as ITU-T Recommendation [http://www.itu.int/rec/T-REC-J.122/en J.122]. Most recently, DOCSIS 3.0 was ratified as ITU-T Recommendation J.222 ([http://www.itu.int/rec/T-REC-J.222.0/en J.222.0], [http://www.itu.int/rec/T-REC-J.222.1 J.222.1], [http://www.itu.int/rec/T-REC-J.222.2 J.222.2], [http://www.itu.int/rec/T-REC-J.222.3 J.222.3]).

Note: While ITU-T Recommendation J.112 Annex B corresponds to DOCSIS/EuroDOCSIS 1.1, Annex A describes an earlier European cable modem system ("[[Digital Video Broadcasting|DVB]] EuroModem") based on ATM transmission standards. Annex C describes a variant of DOCSIS 1.1 that is designed to operate in Japanese cable systems. The ITU-T Recommendation J.122 main body corresponds to DOCSIS 2.0, J.122 Annex F corresponds to EuroDOCSIS 2.0, and J.122 Annex J describes the Japanese variant of DOCSIS 2.0 (analogous to Annex C of J.112).
