This document defines a technology independent model for a set of abstract services that is
located above the application layer of the OSI model, and that is used for exchanging
transaction messages based on the transaction models defined in IEC 62264-5. The model,
which is called the Messaging Service Model (MSM), is intended for interoperability between
manufacturing operations domain applications and applications in other domains.
NOTE It is recognized that other sets of services not defined in accordance with this document are possible for the
exchange of MOM information and are not deemed invalid as a result of this document.

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 physical channel arrangements. DECT physical channels are radio communication
paths between two radio end points. A radio end point is either part of the fixed infrastructure, a privately owned Fixed
Part (FP), typically a base station, or a Portable Part (PP), typically a handset. The assignment of one or more particular
physical channels to a call is the task of higher layers.
The Physical Layer (PHL) interfaces with the Medium Access Control (MAC) layer, and with the Lower Layer
Management Entity (LLME). On the other side of the PHL is the radio transmission medium which has to be shared
extensively with other DECT users and a wide variety of other radio services. The tasks of the PHL can be grouped into
five categories:
a) to modulate and demodulate radio carriers with a bit stream of a defined rate to create a radio frequency
channel;
b) to acquire and maintain bit and slot synchronization between transmitters and receivers;
c) to transmit or receive a defined number of bits at a requested time and on a particular frequency;
d) to add and remove the synchronization field and the Z-field used for rear end collision detection;
e) to observe the radio environment to report signal strengths.
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).
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.

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

This document defines a notation for specifying encodings of ASN.1 types or of parts of types. It provides several mechanisms for such specification, including: –     direct specification of the encoding using standardized notation; –     specification of the encoding by reference to standardized encoding rules; –     specification of the encoding of an ASN.1 type by reference to an encoding structure; –     specification of the encoding using non-ECN notation. It also provides the means to link the specification of encodings to the type definitions to which they are to be applied. ECN does not currently provide any support for specifications using the OID internationalized resource identifier type or the relative OID internationalized resource identifier type (see Rec. ITU-T X.680 | ISO/IEC 8824-1), and these are not referred to further in this Standard.

This document specifies two versions of a mapping from any XSD Schema into an Abstract Syntax Notation One (ASN.1) schema. The ASN.1 schema for both versions support the same semantics and validate the same set of XML documents. This document specifies the final XER encoding instructions that are to be applied as part of the defined mapping to ASN.1 types, but does not specify which syntactic form is to be used for the specification of those final XER encoding instructions, or the order or manner of their assignment. NOTE – Implementers of tools generating these mappings may choose any syntactic form or order of assignment that results in the specified final XER encoding instructions being applied. Examples in this document generally use the type prefix form, but use of an XER Encoding Control Section may be preferred for the mapping of a complete XSD Schema, as a matter of style. There are different ways (syntactically) of assigning XER encoding instructions for use in EXTENDED-XER encodings (e.g., use of ASN.1 type prefix encoding instructions or use of an XER encoding control section). The choice of these syntactic forms is a matter of style and lies outside the scope of this document.

This document specifies a set of basic XML Encoding Rules (BASIC-XER) that may be used to derive a transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1 and Rec. ITU-T X.681 | ISO/IEC 8824-2. This document also specifies a set of Canonical XML Encoding Rules (CXER) which provide constraints on the basic XML Encoding Rules and produce a unique encoding for any given ASN.1 value. This document further specifies a set of extended XML Encoding Rules (EXTENDED-XER) which adds further encoders options, and also allows the ASN.1 specifier to vary the encoding that would be produced by BASIC-XER. It is implicit in the specification of these encoding rules that they are also used for decoding. The encoding rules specified in this document : –     are used at the time of communication; –     are intended for use in circumstances where displaying of values and/or processing them using commonly available XML tools (such as browsers) is the major concern in the choice of encoding rules; –     allow the extension of an abstract syntax by addition of extra values for all forms of extensibility described in Rec.

This part of the IEC 61784-3 series explains some common principles that can be used in the
transmission of safety-relevant messages among participants within a distributed network
which use fieldbus technology in accordance with the requirements of IEC 61508 (all parts) 1
for functional safety. These principles are based on the black channel approach. They can be
used in various industrial applications such as process control, manufacturing automation and
machinery.
This part and the IEC 61784-3-x parts specify several functional safety communication
profiles based on the communication profiles and protocol layers of the fieldbus technologies
in IEC 61784-1, IEC 61784-2 and IEC 61158 (all parts). These functional safety
communication profiles use the black channel approach, as defined in IEC 61508. These
functional safety communication profiles are intended for implementation in safety devices
exclusively.
NOTE 1 Other safety-related communication systems meeting the requirements of IEC 61508 (all parts) can exist
that are not included in IEC 61784-3 (all parts).
NOTE 2 It does not cover electrical safety and intrinsic safety aspects. Electrical safety relates to hazards such
as electrical shock. Intrinsic safety relates to hazards associated with potentially explosive atmospheres.
All systems are exposed to unauthorized access at some point of their life cycle. Additional
measures need to be considered in any safety-related application to protect fieldbus systems
against unauthorized access. IEC 62443 (all parts) will address many of these issues; the
relationship with IEC 62443 (all parts) is detailed in a dedicated subclause of this document.
NOTE 3 Implementation of a functional safety communication profile according to this document in a device is not
sufficient to qualify it as a safety device, as defined in IEC 61508 (all parts).
NOTE 4 The resulting SIL claim of a system depends on the implementation of the selected functional safety
communication profile within this system.
NOTE 5 Annex C explains the numbering scheme used for the technology-specific parts (IEC 61784-3-x) as well
as their common general structure.
NOTE 6 Annex D provides a guideline for the assessment and test of safety communication profiles as well as
safety-related devices using these profiles.

IEC 62769-5:2021 defines the FDI Information Model. One of the main tasks of the Information Model is to reflect the topology of the automation system. Therefore, it represents the devices of the automation system as well as the connecting communication networks including their properties, relationships, and the operations that can be performed on them. The types in the AddressSpace of the FDI Server constitute a catalogue, which is built from FDI Packages. The fundamental types for the FDI Information Model are well defined in OPC UA for Devices (IEC 62541-100). The FDI Information Model specifies extensions for a few special cases and otherwise explains how these types are used and how the contents are built from elements of DevicePackages. The overall FDI architecture is illustrated in Figure 1. The architectural components that are within the scope of this document have been highlighted in this illustration.

The scope of this Recommendation | International Standard is threefold. This Recommendation | International Standard provides guidance on how to prepare new and old protocols for cryptographic algorithm migration, and defines auxiliary cryptographic algorithms to be used for migration purposes. This Recommendation | International Standard specifies a general wrapper protocol that provides authentication, integrity and confidentiality (encryption) protection for other protocols. This wrapper protocol includes a migration path for cryptographic algorithms allowing for smooth migration to stronger cryptographic algorithms as such requirements evolve. This will allow migration to quantum-safe cryptographic algorithms. Protected protocols can then be developed without taking security and cryptographic algorithms into consideration. This Recommendation | International Standard also includes some protocols to be protected by the wrapper protocol primarily for support of public-key infrastructure (PKI). Other specifications, e.g., Recommendations or International Standards, may also develop protocols designed to be protected by the wrapper protocol.
