ITU-T Recommendation M.3343 consented at the Beijing meeting of Study Group 4
outlines the requirements and protocol neutral information model necessary to
communicate trouble tickets in a multi-service provider NGN environment.
NGN according to the Recommendation introduces
new reporting needs to address new service types expected.
The Recommendation describes a trouble in a
communications network as a problem that has an adverse effect on the quality
of service perceived by network users. Management of trouble tickets is
necessary to ensure that they receive attention and that the trouble is cleared
to restore the service.
At the time of a trouble, a network may have
been inter-working with another network to provide a service. Therefore a
standardized way of exchanging trouble management information between
management systems across interfaces is necessary.
