scope:

This European Telecommunication Standard (ETS) contains the test specification for Digital Enhanced Cordless Telecommunications / Global System for Mobile communications (DECT/GSM) Interworking Profile (IWP) Fixed Part (FP) applications as specified in ETS 300 370 [3].

The main objective of the DECT/GSM IWP test specification is to provide approval tests giving a high probability of air interface inter-operability between any DECT FP and any Portable Part (PP) conforming to ETS 300 370 [3] offered by different manufacturers. All FPs conforming to ETS 300 370 [3] and supporting only Access Rights Identity (ARI) class D, as far as DECT Network (NWK) layer is concerned, are tested for conformance only to this ETS.

All FPs conforming to ETS 300 370 [3] and supporting in addition to ARI class D any other ARI classes, as far as DECT NWK layer is concerned, are tested for conformance separately:

- first to ETS 300 494-1 [17] and ETS 300 494-3 [18]; and 

- second to this ETS.

All FPs conforming to ETS 300 370 [3], as far as the Data Link Control (DLC) layer, Medium Access Control (MAC) layer and PHL layer are concerned, are tested to ETS 300 494-1 [17] and ETS 300 494-3 [18].

ISO/IEC 9646 Parts 1 to 7 [19] - [24] are used as the basis for the test methodology, and as the basis for test case specification.

The test cases if listed in this ETS have been derived from ETS 300 497 Parts 1 to 9 [8] - [16] or ETS 300 494-1 [17] and ETS 300 494-3 [18]. Additional DECT/GSM IWP specific test cases are included where required. The Profile IXIT is based on ETS 300 497 Parts 8 to 9 [15] - [0] and GAP Profile IXIT ETS 300 494-1 [17] and ETS 300 494-3 [18].

Annex A contains the Abstract Test Suite (ATS).
