scope:

The present document is a part of the Digital European Cordless Telecommunications/Global System for Mobile Communications (DECT/GSM) interworking profile and specifies requirements needed to ensure that GSM basic services can be provided over the DECT air interface. To enable DECT terminals to inter-work with DECT systems which are connected to the GSM infrastructure, the present document specifies the additions to the GAP specification, ETS 300 444 [12] on which this profile is based. The additions are based on the DECT Common Interface specification given in EN 300 175-1 [2] to EN 300 175-8 [9].From the GSM side the present document assumes interworking with GSM Public Land Mobile Network (PLMN) phase 2. Interworking with GSM Phase 1 is outside the scope of the present document.
