scope:

The present document specifies the additional technical characteristics to be provided by terminal equipment which is capable of connection with a DECT radio access (see note 1) to a public telecommunications network (see note 2) as well as with GSM radio access to GSM Public Land Mobile Networks (PLMN).

A DECT-terminal equipment comprises two elements, referred to as a Fixed Part (FP) and a Portable Part (PP), whereas a GSM terminal equipment is comprised of a mobile station (GSM MS). The objective of the present document is to ensure dual-mode operation of handsets comprised of a DECT PP and a GSM MS (Phase 2). These parts may, or may not, be separable.

The basic CTRs for DECT shall apply. These are the general attachment requirements [CTR 6], and for telephony the requirements for telephony applications [CTR 10] and requirements for the Generic Access Profile [CTR 22]. In addition, further CTRs may apply such as the CTRs for DECT access to GSM PLMN [CTR 36] and/or DECT access to ISDN [CTR 40].

The basic CTRs for GSM shall apply. These are the attachment requirements for Global System Mobile (GSM) mobile stations; Access [CTR 19 for Phase 2 and CTR 31 for multiband operation] and the requirements for telephony [CTR 20 for Phase 2 and CTR 32 for multiband operation].

The present document specifies all necessary additions to the Harmonized Standards rendered mandatory by the applicable CTRs for DECT/GSM dual-mode handsets.

As dual-mode handsets are expected to undergo a rapid technical development, the present documents may be amended at a later stage to meet these developments.

NOTE 1: Currently there are DECT profiles for interworking with ISDN (ETS 300 434 [15] and ETS 300 822 [16], which both allow access to ISDN networks and the services therein), GSM PLMN (ETS 300 370 [1] and others, which allow access to GSM PLMN and the services therein) and Generic Access to fixed networks (EN 300 444 [3], GAP, focusing on speech services). These are all covered by corresponding Harmonized Standards/CTRs. There also exists the CTM Access Profile (EN 300 824 [14], CAP).

NOTE 2: In the cases of the present document, the air interface may also be the network access
