scope:

This European Telecommunication Standard (ETS) specifies that set of technical requirements for Digital Enhanced Cordless Telecommunications (DECT) Fixed Part (FP) and DECT Cordless Terminal Adapter (CTA) for the support of the Radio in the Local Loop (RLL) Access Profile (RAP).

The objective of this ETS is to ensure the air interface interoperability of DECT RAP CTAs and DECT RAP FPs and Wireless Relay Stations (WRSs) if applied.

ETS 300 765-1 [16] contains the so called "Plain Old Telephone Service (POTS)" services including analogue leased lines and 64 kbit/s bearer service. ETS 300 765-1 [16] also provides for optional mobility features by supporting Generic Access Profile (GAP) Portable Part (PP) subscriber terminals and CTAs with WRS GAP functionality.

This ETS contains telecommunication services as offered by Integrated Services Digital Network (ISDN), contemporary non-voiceband data services provided through, for example, a dedicated data port at the CTA, and support of digital leased lines. The provision of the mentioned services is not mandated by this ETS, but if provided they shall be provided as defined (provision optional, process mandatory).

ive is to use as much as possible from existing profiles: DECT/ISDN Intermediate ISDN access Profile (IIP) as defined in ETS 300 822 [19] and the data profile A/B.2 as defined in ETS 300 701 [21], data profile C.2 as defined in ETS 300 651 [22], and data profile F.2 as defined in ETS 300 755 [23]. Therefore, most of the RAP features refer to features defined in other profiles and the necessary additional features (e.g. Operation, Administration and Maintenance (OA&M)) are listed and explained in this ETS.

In addition, this ETS defines additional features, services, procedures, etc. for the CTA and the FT, which are provision mandatory either in the CTA or in the FT, as well as some elements that are provision optional but still process mandatory. These features in particular define the operation and maintenance of CTAs in relation to the provided service (profile) in a public network.
