1 Scope
This European Telecommunication Standard (ETS) defines a profile for Digital Enhanced Cordless
Telecommunications (DECT) systems conforming to ETS 300 175, parts 1 to 8 [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.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
mobility class 1: Local area applications, for which terminals are pre-registered off-air with one or more
specific fixed parts, and establishment of service and user parameters is therefore implicit, according to a
profile-defined list.
mobility class 2: Private and public roaming applications for which terminals may move between fixed
parts within a given domain and for which association of service parameters is explicit at the time of
service request.
multiframe: A repeating sequence of 16 successive Time Division Multiple Access (TDMA) frames, that
allows low rate or sporadic information to be multiplexed (e.g. basic system information or paging).
service type A: Low speed frame relay, with a net sustainable throughput of up to 24 kbits/s, optimized
for bursty data, low power consumption and low complexity applications such as hand-portable
equipment.
service type B: High performance frame relay, with a net sustainable throughput of up to 552 kbits/s,
optimized for high speed and low latency with bursty data. Equipment implementing the type B profile shall
inter-operate with type A equipment.
service type C: Non-transparent connection of data streams requiring Link Access Protocol (LAP)
services, optimized for high reliability and low additional complexity. This builds upon the services offered
by the type A or B profiles.
service type E: A short message transfer or paging service which may be unacknowledged or
acknowledged, optimized for small Service Data Units (SDUs), low Portable Part (PP) complexity and
ultra-low power consumption.

---------------------- Page: 12 ----------------------

SIST ETS 300 757 E1:2003
Page 11
ETS 300 757: April 1997
service type F: An application profile specifically supporting teleservices such as fax, building upon the
services offered by the type A/B and C profiles, optimized for terminal simplicity, spectrum efficiency and
network flexibility.
TDMA frame: A time-division multiplex of 10 ms duration, containing 24 successive full slots. A TDMA
frame starts with the first bit period of full slot 0 and ends with the last bit period of full slot 23.

4 Description of services
4.1 General
The DECT data profile defined in this ETS has been intended for message transfer or paging and is
optimized for small SDUs, low PP complexity and ultra-low power consumption. Two service types are
defined: Low Rate Messaging Service Point-To-Point (LRMS PTP) which may be unacknowledged or
acknowledged used for point-to-point messaging and Low Rate Messaging Service Point-To-Multipoint
(LRMS PTM) used for point-to-multipoint messaging. The LRMS PTM is an optional feature while LRMS
PTP support is mandatory if this profile is supported.
The LRMS PTP and PTM may co-exist with other profiles and their existence should not have any effect
on the functionality of the other existing profiles. That is, the LRMS functionality should have a secondary
priority in respect to the profile relations.
4.2 Low Rate Messaging Service Point-To-Point (LRMS PTP)
The objectives of the data profile service type E, class 2 LRMS PTP are as follows:
The LRMS PTP is a generic set of commands, information elements and functionality for file/messaging
service. In most of the cases LRMS can be regarded as a DECT internal teleservice that can be
interworked to the similar services in external networks. In addition LRMS PTP provides means to convey
transparently applicati
