ITU-T Recommendations

This Recommendation describes a Residential Gateway by providing a set of IP-based features that may be added to a Cable Modem or incorporated into a standalone device. This will enable cable operators to provide an additional set of enhanced home network-based services to their customers including support for Quality of Service (QoS), device and service discovery, enhanced security, firewall management, home network focused management and provisioning features, managed network address translation, improved addressing and packet handling and LAN device diagnostics. This Recommendation is based upon the architectural frameworks defined in ITU-T Rec. J.190.This Recommendation represents an enhancement to ITU-T Rec. J.191, retaining a majority of J.191 functionality as a foundation, and building upon this base to provide additional advanced features. A key design goal for equipment conforming to this Recommendation is interoperability with equipment conforming to ITU-T Rec. J.191. For example, common MIBs are used for the foundational functionality. As a result, a J.192-based headend may manage a mixed J.191 and J.192 deployment.
