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) necessary for the support of the Radio in the Local Loop (RLL) Access Profile (RAP).

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

In addition, this ETS defines the 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.

Another objective is to use as much as possible from the existing Generic Access Profile (GAP), but to exclude the not applicable GAP features. Therefore most of the RAP features refer to GAP features and the necessary additional features (for example Operation, Administration, and Maintenance (OA&M)) are listed and explained in this document.

This ETS contains the so-called "Plain Old Telephone Service (POTS)" services including leased lines and 64 kbit/s bearer service.
