scope:

This TBR covers the general attachment requirements for terminal equipment for the Digital European Cordless Telecommunications (DECT) common interface.

This TBR contains the procedures and requirements for the type examination of Digital European Cordless Telecommunications (DECT) equipment supporting a 3,1 kHz telephony teleservice.

This TBR is based on the DECT Common Interface ETS 300 175 [1] - [8] and [32], and I-ETS 300 176 [31].

This TBR specifies the technical characteristics particular to telephony applications provided by terminal equipment which is capable of connection to a public telecommunications network and which uses DECT. The cordless transmissions for such terminal equipment operate within the frequency band 1 880 to 1 900 MHz.

The objective of this TBR is to ensure interworking of terminal equipment via the public network.

The requirements in this TBR apply in addition to the attachment requirements for the appropriate public network (see note) and TBR 6 [22].

NOTE: TBR for basic ISDN, TBR for primary rate ISDN, or national regulations (implementing ETS 300 001 [29]) for Public Switched Telephone Network (PSTN). Interconnection of a DECT terminal to a GSM network is still under study; in due course, the scope statement may need amending to reflect this point.

This TBR is applicable to simple telephony terminals as well as to the telephony function of multifunction or multiservice terminals.

This TBR includes the speech quality and transmission requirements for a 3,1 kHz telephony teleservice.

For each requirement in this TBR, a test is given, including measurement methods. The terminal equipment may be stimulated to perform the tests by additional equipment if necessary.

This TBR is not applicable to terminal equipment specially designed for the disabled (e.g. with amplification of received speech as an aid for the hard-of-hearing).

DECT comprises two equipment elements, referred to as a Fixed Part (FP) and a Portable Part (PP). This TBR is structured to allow type approval of either a) the FP and PP together, or b) the FP and PP as separate items. Where the DECT FP is connected to a PSTN, and there are any national peculiarities in the requirements for voice telephony, these are accommodated within the FP.
