1 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.

2 Normative references

This ETS incorporates by dated and undated reference, provisions from other publications. These

normative references are cited at the appropriate places in the text and the publications are listed

hereafter. For dated references, subsequent amendments to or revisions of any of these publications

apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest

edition of the publication referred to applies.
[1] ITU-T Recommendation I.353: "Reference events for defining ISDN and B-ISDN
performance parameters".
[2] I-ETS 300 465: "Broadband Integrated Services Digital Network (B-ISDN);
Availability and Retainability performance for B-ISDN semi permanent
connections".
[3] ITU-T Recommendation I.356: "B-ISDN ATM layer cell transfer performance".

NOTE: ITU-T Recommendation I.356 is used as a normative reference rather than the ETSI

equivalent I-ETS 300 464, as ITU-T Recommendation I.356 contains important

information yet to be incorporated in the I-ETS 300 464. It should be noted that the
