Digital Enhanced Cordless Telecommunications (DECT) - Common Interface (CI) - Part 6: Identities and addressing
ETSI EN 300 175-6 V2.9.1 (2022-03)

The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications
(DECT) Common Interface (CI).
The present document specifies the identities and addressing structure of the Digital Enhanced Cordless
Telecommunications (DECT) Common Interface (CI).
There are four categories of identities to be used for identification and addressing in a general DECT environment.
These four categories are:
• Fixed Part (FP) identities;
• Portable Part (PP) identities;
• connection-related identities;
• equipment-related identities.
Fixed part identities and portable part identities are used for:
• access information from fixed parts to portable parts;
• access requests from portable parts;
• identification of portable parts;
• identification of fixed parts and radio fixed parts;
• paging;
• billing.
These identities support:
• different environments, such as residential, public or private;
• supply to manufacturers, installers, and operators of globally unique identity elements with a minimum of
central administration;
• multiple access rights for the same portable;
• large freedom for manufacturers, installers, and operators to structure the fixed part identities, e.g. to facilitate
provision of access rights to groups of DECT systems;
• roaming agreements between DECT networks run by the same or different owners/operators;
• indication of handover domains;
• indication of location areas, i.e. paging area;
• indication of subscription areas of a public service.
The present document also provides for length indicators and other messages that can override the default location
and/or paging area and domain indications given by the structure of the identities.
Connection related identities are used to identify the protocol instances associated with a call and are used for
peer-to-peer communication.
Equipment related identities are used to identify a stolen PP and to derive a default identity coding for PP emergency
call set-up.
Coding of identity information elements for higher layer messages is found in ETSI EN 300 175-5 [5], clause 7.7.
User authentication and ciphering need additional key information and is outside the scope of the present document, but
is covered in other parts of ETSI EN 300 175 [1] to [8], e.g. ETSI EN 300 175-7 [7].
The present document includes New Generation DECT, a further development of the DECT standard introducing
wideband speech, improved data services, new slot types and other technical enhancements.

The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications
(DECT) Common Interface (CI).
This part of the DECT CI specifies the speech and audio coding and transmission requirements.
In order to ensure satisfactory interworking of different portable and fixed units, it is necessary to specify the
transmission performance of the analog information over the digital link. This requires not only use of a common
speech algorithm, but also standardization of frequency responses, reference speech levels (or loudness) at the air
interface and various other parameters.
The present document applies to DECT equipment which includes all the necessary functions to provide real-time
two-way speech conversation and stereo audio transmission. Several speech services are defined in the present
document, including conventional 3,1 kHz telephony, wideband 7 kHz voice transmission, super-wideband 14 kHz and
fullband 20 kHz service. DECT Fixed part providing such services may be connected to the public circuit switched
(PSTN/ISDN) network, to private networks or to the Voice over Internet Protocol (VoIP) network.
Tethered fixed point local loop applications are not required to comply with the requirements of the present document.
For the DECT systems which connect to the Public Switched Telephone Network (PSTN) via an analog interface, the
additional requirements, which are implemented in the FP, have as much as possible been aligned with ETSI
TBR 038 [29].
A summary of the control and the use of the DECT echo control functions, to guide on need for options to
manufacturers and installers, is found in annex A.
Information concerning test methods can be found in ETSI EN 300 176-1 [9] and ETSI EN 300 176-2 [10] (previously
covered by ETSI TBR 010 [i.5]). The test methods take into account that DECT is a digital system.
The present document includes New Generation DECT, a further development of the DECT standard introducing
wideband speech, improved data services, new slot types and other technical enhancements.
In addition, the present document includes DECT Evolution, providing SWB and FB speech and audio capabilities and
a new speech coding algorithm for NB and WB allowing to increase the audio quality of the NB and WB speech service
and improve bandwidth efficiency.
The latest update for DECT Evolution includes the support of ultra-band, high resolution, low-latency speech and audio
coding, and additional PP types supported with LC3plus coding. An application profile using these new PP types can be
found in ETSI TS 103 706 [i.28].

Digital Enhanced Cordless Telecommunications (DECT) - Common Interface (CI) - Part 5: Network (NWK) layer
ETSI EN 300 175-5 V2.9.1 (2022-03)

The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications
(DECT) Common Interface (CI).
The present document specifies the Network (NWK) layer. The NWK layer is part 5 of the ETSI EN 300 175 and
layer 3 of the DECT protocol stack.
The present document only specifies the C-plane (control plane) of the DECT NWK layer. It contains no specification
for the U-plane (user plane) because the U-plane is null for all services at the DECT NWK layer.
The C-plane contains all of the internal signalling information, and the NWK layer protocols are grouped into the
following families of procedures:
• Call Control (CC);
• Supplementary Services (SS);
• Connection Oriented Message Service (COMS);
• ConnectionLess Message Service (CLMS);
• Mobility Management (MM);
• Link Control Entity (LCE).
The present document uses the layered model principles and terminology as described in Recommendation ITU-T
X.200 [i.3] and Recommendation ITU-T X.210 [i.4].
The present document includes New Generation DECT, a further development of the DECT standard introducing
wideband speech, improved data services, new slot types and other technical enhancements. The present document also
includes super-wideband and fullband speech and audio services.

Digital Enhanced Cordless Telecommunications (DECT) - Common Interface (CI) - Part 7: Security features
ETSI EN 300 175-7 V2.9.1 (2022-03)

The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications
(DECT) Common Interface (CI).
The present document specifies the security architecture, the types of cryptographic algorithms required, the way in
which they are to be used, and the requirements for integrating the security features provided by the architecture into the
DECT CI. It also describes how the features can be managed and how they relate to certain DECT fixed systems and
local network configurations.
The security architecture is defined in terms of the security services which are to be supported at the CI, the
mechanisms which are to be used to provide the services, and the cryptographic parameters, keys and processes which
are associated with these mechanisms.
The security processes specified in the present document are each based on one of three cryptographic algorithms:
• an authentication algorithm;
• a key stream generator for MAC layer encryption; and
• a key stream generator plus a Message Authentication Code generator for CCM authenticated encryption.
The architecture is, however, algorithm independent, and either the DECT standard algorithms, or appropriate
proprietary algorithms, or indeed a combination of both can, in principle, be employed. The use of the employed
algorithm is specified in the present document.
Integration of the security features is specified in terms of the protocol elements and processes required at the Network
(NWK) and Medium Access Control (MAC) layers of the CI.
The relationship between the security features and various network elements is described in terms of where the security
processes and management functions may be provided.
The present document does not address implementation issues. For instance, no attempt is made to specify whether the
DSAA or DSAA2 should be implemented in the PP at manufacture, or whether the DSAA, DSAA2 or a proprietary
authentication algorithm should be implemented in a detachable module. Similarly, the present document does not
specify whether the DSC or DSC2 should be implemented in hardware in all PPs at manufacture, or whether special
PPs should be manufactured with the DSC, DSC2 or proprietary ciphers built into them. The security architecture
supports all these options, although the use of proprietary algorithms may limit roaming and the concurrent use of PPs
in different environments.
Within the standard authentication algorithms, DSAA2, DSC2 and CCM are stronger than DSAA and DSC and provide
superior protection. DSAA2 and DSC2 are based on AES [10] and were created in 2011. CCM is also based on
AES [10] and was added to the standard in 2012.
The present document includes New Generation DECT, a further development of the DECT standard introducing
wideband speech, improved data services, new slot types and other technical enhancements.
The present document also includes DECT Ultra Low Energy (ULE), a low rate data technology based on DECT
intended for M2M applications with ultra low power consumption.

Digital Enhanced Cordless Telecommunications (DECT) - Common Interface (CI) - Part 4: Data Link Control (DLC) layer
ETSI EN 300 175-4 V2.9.1 (2022-03)

The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications
(DECT) Common Interface (CI).
The present document specifies the Data Link Control (DLC) layer. The DLC layer is part 4 of the DECT CI standard
and layer 2b of the DECT protocol stack.
Two planes of operation are specified for this DLC (sub)layer. These planes are called the Control plane (C-plane) and
the User plane (U-plane).
The C-plane is mostly concerned with the DECT signalling aspects. It provides a reliable point-to-point service that
uses a link access protocol to offer error protected transmission of Network (NWK) layer messages. The C-plane also
provides a separate point-to-multipoint (broadcast) service (Lb).
The U-plane is only concerned with end-to-end user information. This plane contains most of the application dependent
procedures of DECT. Several alternative services (both circuit-mode and packet-mode) are defined as a family of
independent entities. Each service provides one or more point-to-point U-plane data links, where the detailed
characteristics of those links are determined by the particular needs of each service. The defined services cover a wide
range of performance, from "unprotected with low delay" for speech applications to "highly protected with variable
delay", for local area network applications.
NOTE: The performance of the DLC services need not be tight to any particular application. For example the
"unprotected with low delay" service could also be used for data applications, e.g. if some data protection
is provided outside the DECT protocol.
The present document uses the layered model principles and terminology as described in Recommendations ITU-T
X.200 [14] and X.210 [15].
The present document includes New Generation DECT, a further development of the DECT standard introducing
wideband speech, improved data services, new slot types and other technical enhancements.
