Summary

Recommendation ITU-T J.262 is one of a series of Recommendations to enable support for preferential telecommunication services over IPCablecom networks. It defines the specifications for authentication in preferential telecommunications 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 defines specifications for authentication only. Authentication must be utilized to prevent unauthorized use of premium services and for emergency services in IPCablecom2 that may require preferential treatment (e.g., telecommunications for disaster relief and the emergency telecommunications service).

User authentication is necessary to determine whether to authorize a request for preferential telecommunication services. This Recommendation covers only authentication and does not address which services the authenticated user is authorized to use.
