The present document specifies the technical characteristics to be provided by terminal equipment which is capable of
connection to a Integrated Services Digital Network (ISDN) and which uses Digital European Cordless
Telecommunications (DECT) for network access. The cordless transmissions for such terminal equipment operate
within the frequency band 1 880 MHz to 1 900 MHz.
A DECT terminal equipment comprises two elements, referred to as a Fixed Part (FP) and a Portable Part (PP). The
objective of the present document is to ensure air-interface interoperability between a FP and PP following the
DECT/ISDN Interworking Profile (IWP) (see note 2), where these parts are capable of 3,1 kHz telephony applications,
and where the FP is connected to the ISDN in order to provide ISDN services (according to TBR 3 [39] and
TBR 4 [40]), over the DECT air interface.
For functional parts of a FP, that are terminal equipment and which are declared to conform to the basic Common
Technical Regulations (CTRs) for DECT (see note 1) and to the DECT/ISDN IWP, the requirements of the present
document shall apply, in addition to the attachment requirements for the appropriate ISDN.
The requirements of the present document is also applicable for the complete set of functionality of a PP declared to
conform to the DECT/ISDN IWP. For a PP, the present document is in addition to the basic CTRs for DECT
(see note 1).
Where a feature is indicated as optional it need not be provided, but where such a feature is provided, the FP and/or PP
shall conform to the requirements and tests of the present document. the present document is structured to allow type
approval of the FP and PP as separate items. For each requirement in the present document, a test is given, including
measurement methods where applicable. The terminal equipment may be stimulated to perform the tests by additional
equipment if necessary.
