Foreword
GY/T 200 "Technical Specifications for HFC Network Data Transmission System" is divided into the following two parts.
-Part 1. General requirements;
-Part 2. RF interface and protocol.
This part is the second part of GY/T 200.
This section adopts ITU-T J.112 "Transmission Systems for Interactive Cable Television
Services ", mainly adopting Appendix B (Data-over-cable radio frequency interface) of this proposal. This section is related to
The main difference of ITU-T J.112 Appendix B is that the dynamic QoS allocation mechanism has been expanded according to the advanced principles of the standard and China's actual situation.
And payload header suppression technology, delete the related content related to encryption in the original Recommendation, and its related content is separately stipulated in other standards.
Appendix A, Appendix B, Appendix C, Appendix D, Appendix H, and Appendix I of this section are normative appendixes, Appendix E, Appe
