scope:

The present document has been prepared to provide a model for designing and operating the checking of metering and billing processes and systems of Service Providers (SP). It does not provide any model for designing and operating metering and billing process systems.

The goal of this specification is to define a standardized checking process that could be implemented by any stakeholder and is auditable by a third-party, leading to trustworthy performance indicators about the integrity of billing issued by a Service Provider.

Because the checking process of this technical specification is end-to-end (i.e. using a "black box" approach from the actual Electronic Communications generation to the verifying of its billing), it is intended that these requirements are applicable to any kind of services offered by the Service Providers.
