scope:

This European Telecommunication Standard (ETS) is a part of the Digital Enhanced Cordless Telecommunications / Global System for Mobile communications (DECT/GSM) Interworking Profile (IWP) and specifies the Portable Part (PP) interworking requirements and Fixed Part (FP) interworking requirements/mappings necessary to ensure that the GSM facsimile group 3 service can be provided over DECT, as specified in ETS 300 466 [13]. To enable DECT terminals to interwork with DECT systems which are connected to the GSM infrastructure, from the DECT side this ETS is based on ETS 300 755 [24].

NOTE: The DECT data service profile is based upon the Generic Access Profile (GAP) ETS 300 444 [12] and on the DECT Common Interface specification ETS 300 175, parts 1 to 8 [1] to [8].

Interworking functions/mappings are specified for Mobile Switching Centre (MSC) attachment for the DECT FP as the FP is using the A-interface towards the GSM MSC in the respect that the FP emulates a GSM Base Station Controller (BSC) with regards to the GSM messages which are relevant to this ETS. The complete interface used between the DECT Fixed Part (FP) and the GSM Mobile Switching Centre (MSC) is specified in ETS 300 499 [14]. Attachment via other interfaces to GSM-networks is outside the scope of this ETS.

The DECT access protocols and FP and PP interworking/mappings necessary for the support of basic voice telephony service are specified in ETS 300 370 [10]. Support of bearer services is specified in ETS 300 756 [25].
