scope:

This European Telecommunication Standard (ETS) defines a profile for Digital Enhanced Cordless Telecommunications (DECT) systems conforming to ETS 300 175 [1] - [8]. It is part of a family of profiles aimed at the general connection of terminals supporting non-voice services to a fixed infra-structure, private and public.

The Low Rate Messaging Service (LRMS), specified in this ETS, provides a means for the slow, acknowledged or unacknowledged, transfer of multimedia message objects, including alphanumeric paging messages. It provides both point-to-point and point-to-multipoint messaging and exploits the Multimedia Messaging Service (MMS) specified ETS 300 755 [13]. This service may be used for private and public roaming applications.

This ETS specifies the Type E Service, Mobility Class 2, as described in ETR 185 [11]. The service employs solely C-plane functionality and has been designed to coexist with other profiles such as the Generic Access Profile (GAP), ETS 300 444 [9] or the Global System for Mobile communication (GSM) Interworking Profile, ETS 300 370 [10]. No User plane (U-plane) functionality is required for the service.

Interworking with the GSM Short Message Service (SMS) is specifically provided for in an annex of this ETS which cross-references to GSM interworking profile standards (see ETS 300 764 [14]).

This ETS defines the requirements on the Physical (PHL), Medium Access Control (MAC), Data Link Control (DLC) and Network (NWK) layers of DECT. The standard also specifies Management Entity requirements and generic Interworking Conventions which ensure the efficient use of the DECT spectrum.
