1 Scope
The present document specifies a profile for Digital Enhanced Cordless Telecommunications (DECT) systems
conforming to EN 300 175-1 [1], EN 300 175-2 [2], EN 300 175-3 [3], EN 300 175-4 [4], EN 300 175-5 [5],
EN 300 175-6 [6] and EN 300 175-7 [7]. 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 type D service, mobility class 2, as described in the ETR 185 [9] supports Isochronous Data Bearer Services
(IDBSs) with mobility and is suitable for transparent transfer of isochronous data streams. It is intended for use in
private and public roaming applications. Video telephony, video conferencing and secure telephone services
(end-to-end encrypted) over external networks can be considered as applications of IDBS.
Phase 1 of the present document defines an unprotected service offering an unrestricted digital 32 kbit/s data bearer
service, strongly based on the Generic Access Profile (GAP) (defined in EN 300 444 [8]), and an unprotected single
bearer, multi-rate, rate adaptation service to interwork to synchronous ITU-T Recommendations V.series interfaces.
In addition to the above, the current D.2 service supports an asynchronous version of the unprotected single bearer,
multi-rate, rate adaptation service to interwork with asynchronous ITU-T Recommendations V.series interfaces.
Further phases of this profile may additionally provide multiple rate, multibearer support and limited error correction
capability for services/applications requiring higher rates and high quality isochronous data transmission.
The present document specifies the requirements on the Physical (PHL) layer, Medium Access Control (MAC) layer,
Data Link Control (DLC) layer and Network (NWK) layer of DECT. The present document also specifies Management
Entity (ME) requirements and generic Interworking Conventions (IC).

3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
a) the definitions in EN 300 444 [8]; and
b) the following terms:
bearer service: type of telecommunications service that provides the capability for the transmission of signals between
user/network interfaces. For DECT systems, the Air (Radio) interface provides the bearer services between the DECT
Fixed radio Termination and the DECT Portable radio Termination.
isochronous: pertaining to a signal or a time-varying phenomenon characterized by significant instants separated by
time intervals having a duration theoretically equal to the duration of a unit interval or to an integral multiple of this
duration (CCITT Recommendation R.140 [17]).
mobility class 1: closed user groups, for which terminals are pre-registered off-air with one or more specific Fixed
Parts (FP), 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 FPs within a given
domain and for which association of service parameters is explicit at the time of service request.
service: set of functions offered to a user by an organization.
synchronous: essential characteristics of time-scales or signals such that their corresponding significant instants occur
at precisely the same average rate (not in CCITT Recommendation R.140 [17]).
synchronous transmission: transmission using isochronous signals in which the sending and receiving instruments are
operating continuously in a constant time difference between corresponding significant instants
(CCITT Recommendation R.140 [17]).
