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
