Page 11ETS 300 755: May 19971ScopeThis European Telecommunication Standard (ETS) defines a profile for Digital Enhanced CordlessTelecommunications (DECT) systems conforming to ETS 300 175 [1] to [9]. It is part of a family of profileswhich build upon and extend each other, aimed at the general connection of terminals supporting non-voice services to a fixed infra-structure, private and public.This ETS specifies the type F service, mobility class 2, as described in ETR 185 [12]. It uses the C-planeand U-plane services provided by the data service profile type C, Class 2, ETS 300 651 [13]. Additionalfunctionality is defined to provide a means for the high speed, acknowledged or unacknowledged, transferof multimedia message objects, including group 3 facsimile. This service may be used for private andpublic roaming applications.Annexes to this ETS contain interworking conventions to specific teleservices and application levelservices including group 3 facsimile. The messaging service specified in this ETS also allows efficientinterworking to other message-based teleservices and application-level services, such as E-mail, WorldWide Web (WWW) Hyper Text Transfer Protocol (HTTP) and file transfer (FTP, FTAM and ISDN filetransfer). This messaging service has been optimized for the efficient utilization of the DECT air interfaceand guarantees interoperability for a minimum set of services independently of the terminal application.This ETS defines the requirements on the Physical, MAC, DLC and Network layers of DECT. This ETSalso specifies management entity requirements and generic Interworking Conventions which ensure theefficient use of the DECT spectrum.2Normative referencesThis ETS incorporates, by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listedhereafter.
