Foreword
This European Telecommunication Standard (ETS) has been produced by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
Details of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI) may be
found in ETS 300 175 Parts 1 to 9 [1] - [9].
Further details of the DECT system may be found in ETR 015 [52], ETR 043 [51], and ETR 056 [53].
This ETS consists of two parts as follows:
Part 1: Interworking specification;
Part 2: Access profile.
The annexes A, B, and C are normative, and annex D is informative, to this ETS.
Transposition dates
Date of adoption of this ETS: 15 March 1996
Date of latest announcement of this ETS (doa): 31 July 1996
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 January 1997
Date of withdrawal of any conflicting National Standard (dow): 31 January 1997
Introduction
This ETS specifies how Integrated Services Digital Network (ISDN) services are provided over the DECT
air interface.
One of the main objectives is to describe how the ISDN services are mapped across the DECT air
interface in a formal way, so that inter-operability of different manufacturers' equipment can be achieved.
This is achieved by describing the Interworking Unit (IWU) procedures and mappings loosely following
ITU-T Recommendations Q.601 to Q.699 [68] and by describing air interface protocols.
Part 1 of this ETS is made up of 3 main clauses:
- clause 4: Interworking requirements which includes the reference configurations and the protocol
architecture model and a description of the main service requirements;
- clause 5: IWU mappings which shows the C-plane and U-plane mappings. The signalling mappings
are first described in terms of IWU procedures with informative data flow diagrams. Detailed
descriptions follow using tables of what is mapped, what is ignored, and what is "piped";
- clause 6: Support of ISDN bearer services which identifies the main DECT connection types
(U-plane + C-plane) at the air interface supporting optimized groups of services, from the IWU
mappings.
Part 2 of this ETS contains the ISDN Access Profile (IAP) for the end system and describes the air
interface protocol in detail. It will enable the subsequent generation of Protocol Implementation
Conformance Statements (PICS) and test cases.

1 Scope
This European Telecommunication Standard (ETS) specifies how Integrated Services Digital Network
(ISDN) services may be provided over Digital Enhanced Cordless Telecommunications (DECT)
endsystem configurations. Apparatus claiming interoperability based upon the ISDN Access Profile (IAP)
shall fully comply with the process mandatory technical requirements and those for optional features so far
such are provided. Both public ISDN and private ISDN are within the scope of this ETS.
An IAP is specified, defining how particular ISDN services are supported, so that inter-operability of DECT
equipment can be achieved at the air interface for these services. Apparatus claiming the provision of any
service feature listed in this ETS should comply with the corresponding process mandatory technical
requirements.
The following ISDN bearer services are covered:
- speech;
- 3,1 kHz audio; and
- unrestricted digital information 64 kbit/s.
Applications using these bearer services are outside the scope of this ETS. However, such applications
envisaged include 3,1 kHz telephony, 7 kHz telephony, group 4 fax, teletex, videotex, and voice-band data
transmission such as group 3 fax and modem data transmission.
The bearer service "packet mode" is outside the scope of this ETS.
The support of ISDN supplementary services is considered.
The DECT end system reference configuration is used where the DECT Fixed System (DFS) and DECT
Portable System (DPS) together form an end system with the behaviour of an ISDN Terminal Equipment
(ISDN-TE).
Mobility Management (MM) such as location registration, and subscription registration is outside the scope
of this ETS.
