------------------------------------------------------ 简介:Digital Enhanced Cordless Telecommunications (DECT);General terminal attachment requirements
Foreword
This Technical Basis for Regulation (TBR) has been produced by the Digital Enhanced Cordless
Telecommunications (DECT) Project of the European Telecommunications Standards Institute (ETSI).
The present document has been produced by ETSI in response to a mandate from the European
Commission issued under Council Directive 98/13/EC [12] (as amended) laying down a procedure for the
provision of information in the field of technical standards and regulations.
The present document is intended to become a Harmonized Standard as requested by the above
mentioned mandate, the reference of which will be published in the Official Journal of the European
Communities referencing the Council Directive on the approximation of the laws of the Member States
concerning telecommunications terminal equipment, including the mutual recognition of their conformity
(Directive 98/13/EC [12], known as the "TTE Directive").
A common technical regulation may be established by the European Commission in accordance with the
Directive.
Technical specifications relevant to the 98/13/EC [12] Directive are given in the TBR Requirements Table
(TBR-RT) in annex I.
This TBR covers the general attachment requirements for terminal equipment for the Digital Enhanced
Cordless Telecommunications (DECT) common interface.
The present document contains the procedures and requirements for the type examination of DECT
equipment.
DECT equipment capable of being physically attached to the public network also needs to meet the
appropriate attachment requirements. Speech attachment requirements are covered in TBR 10 (see
annex A).
The present document is based on the DECT Common Interface (CI) given in EN 300 175,
parts 1 [1] to 8 [8].
The present document specifies the technical characteristics to be provided by terminal equipment which
is capable of connection to a public telecommunications network and which uses DECT cordless
communications for network access. The cordless transmissions for such terminal equipment operate
within the frequency band 1 880 MHz to 1 900 MHz.
The objective of the present document is to ensure that no disturbance occurs to the public network, and
to ensure interworking between network and terminal so that calls can be routed successfully through the
network, but without any guarantee of terminal to terminal operation.
The requirements in the present document applies together with the attachment requirements for the
appropriate public network and the requirements of any other relevant TBR. It does not add to or reduce
the attachment requirements unless there is a particular effect on the network which is unique to DECT.
A DECT terminal equipment comprises two elements, referred to as a Fixed Part (FP) and a Portable Part
(PP). The present document is structured to allow type approval of the FP and PP as separate items.
Because of the need for effective use of the radio frequency spectrum, the air interface characteristics
between FP and PP are tested.
For each requirement, a test is given, including measurement methods. Requirements apply at the public
network interface of the terminal equipment, which may be stimulated to perform. the tests by additional
equipment if necessary.
Terminal equipment may be subject to additional or alternative requirements in other Common Technical
Regulations (CTRs) depending on its functionality, in particular if it supports a service which is considered
a justified case for regulation of terminal equipment interworking via the public telecommunications
network.
