scope:

The present document 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 Digital Enhanced Cordless Telecommunications (DECT). The cordless transmissions for such terminal equipment operate within the frequency band 1 880 MHz - 1 900 MHz.

The objective of the present document is to ensure interworking of terminal equipment via the public network.

The requirements in the present document apply in addition to the attachment requirements for the appropriate public network and the TBR for DECT general attachment requirements

The present document is applicable to simple telephony terminals as well as to the telephony function of multi-function or multi-service terminals.

The present document includes the speech quality and transmission requirements for a 3,1 kHz telephony teleservice.

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

The present document 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). The present document 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 peculiarities in the requirements for voice telephony, these shall be accommodated within the FP.
