Foreword
This European Standard (Telecommunications series) has been produced by ETSI Project Digital Enhanced Cordless
Telecommunications (DECT).

Introduction
The present document replaces the former ETS 300 757, known as the E.2 profile, and the former ETS 301 678 (never
published), known as CTM FP2. It defines profiles for Digital Enhanced Cordless Telecommunications (DECT)
systems conforming to EN 300 175 parts 1 [1] to 8 [8]. It is part of a family of profiles aimed at the general connection
of terminals supporting non-voice services to a fixed infrastructure, private and public.

1 Scope
The Low Rate Messaging Service (LRMS), specified in the present document, provides a means for the slow,
acknowledged or unacknowledged, transfer of multimedia message objects, including the Short Message Service
(SMS). It provides both point-to-point and point-to-multipoint messaging. This service may be used for private and
public roaming applications.
The present document defines the requirements on the Physical (PHY), 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.
The present document further mandates how to implement a GSM like Short Message Service (SMS), Point to Point
(PTP), which uses a sub-set of the Low Rate Messaging Service (LRMS) mentioned before as a bearer service.
SMS-PTP includes the following two services:
- SMS Mobile Originated (SMS-MO), for transport of short messages from PT to FT;
- SMS Mobile Terminated (SMS-MT), for transport of short messages from FT to PT.
The Short Message Service, Cell Broadcast is outside the scope of the present document.
In order to facilitate re-use of excising GSM Service Centres, the present document applies the upper GSM protocols
up-to and including the GSM SMS-RP protocol. Therefore, interworking functions handling the encapsulation of GSM
SMS-RP messages are specified.
The following picture shows the protocols defined in the present document.
