适用范围

The main aim of this Recommendation is to give complete guidance for the characterization and assessment, in operation, of the performance of bearer CSCT 64 kbit/s UDI ISDN services by a set of operational NP/QOS measures, related to all the main functions/phases of an ISDN call (setup, information transfer, release). The values measured for these parameters are mainly used for Operation, but also for Administration and Maintenance (OAM) purposes, and for managing Service Level Agreements (SLAs) and Service Quality Agreements (SQAs) [21] with customers and other ROAs.
