scope:
The purpose of this European Telecommunication Standard (ETS) is to specify retainablility parameters and measurement methods for Broadband Integrated Services Digital Network (B-ISDN) point to point Asynchronous Transfer Mode (ATM) switched connections.
An International B-ISDN point to point ATM switched connection is partitioned into two National Portions (NPs), and an International Portion (IP).
The IP is further partitioned into connection portions delimited by international measurement points (MPIs) as defined in ITU-T Recommendations I.353 [1] and I.356 [3]: International Transit Portions (ITPs) and International Inter-operator Portions (IIPs).
A later version of this ETS will specify objectives for the retainability performance of National Portions, International Transit Portions and International Inter-operator Portions.
It is not currently planned to specify end-to-end objectives for retainability performance. Annex B provides guidelines for deriving end-to-end objectives from connection portion objectives.
