Summary

Recommendation ITU-T J.263 is one of a series of Recommendations to enable support for preferential telecommunication services over IPCablecom2 networks. It defines the specifications for priority for preferential telecommunication services over IPCablecom2 networks. These specifications satisfy the requirements defined in Recommendation ITU-T J.260. The essential aspects of preferential telecommunications over IPCablecom2 can be grouped into two areas: prioritization and authentication. This Recommendation provides specifications for prioritization only. Prioritization may be utilized for premium services and for emergency services in IPCablecom2 that may require preferential treatment (e.g., telecommunications for disaster relief and the emergency telecommunications service).

The implementation of priority and authentication is necessary for the support of preferential telecommunications services in IPCablecom networks. This Recommendation only covers technical aspects for achieving prioritized treatment in IPCablecom2 networks.
