This Recommendation contains the requirements and analysis for the business-to-business (B2B)
and customer-to-business (C2B) interfaces of trouble administration for NGN. It assumes a multiservice
provider environment and is aimed at trouble administration functions to support the
deployment of NGN and includes both the B2B and C2B interfaces. B2B/C2B interface is a
synonymous term to X Interface.
Trouble administration consists of processes utilizing trouble report management, testing
management, appointment management and SLA management. This Recommendation and the
current [ITU-T X.790] are specific to trouble report. Functions for testing of the service or transport
stratum, appointment management and SLA management are outside the scope of this
Recommendation. Trouble administration will require all the functions defined in this
Recommendation and the other three Recommendations to provide a complete set of functions.
Third-party request/response operations are dependent upon the privacy business rules defined in
the SC/SP's contract and consequently are considered out of scope for this Recommendation.
