ČSN EN IEC 61968-13 ed. 2 Tato norma specifikuje profily, které lze použít k výměně síťových modelů ve společnostech nebo mezi společnostmi a externími aplikacemi. Tento dokument obsahuje seznam profilů, které umožňují modelovat vyvážené a nevyvážené distribuční sítě za účelem provedení analýzy sítě (Power flow calculation). Proto využívá již existující profily (IEC 61970-45x podle IEC 61970-301 (základna CIM) nebo profily podle IEC 61968-11 Rozšíření CIM pro distribuci). Tento dokument znovu použije některé profily bez jakékoli změny, případně je rozšíří nebo omezí. Kromě toho navrhuje další profily, které by odrážely potřeby distribuce.

ČSN EN IEC 61375-2-8 This part of IEC 61375 applies to all equipment and devices implemented according to IEC 61375-2-3:2015, IEC 61375-2-5:2014 and IEC 61375-3-4:2014, i.e. it covers the procedures to be applied to such equipment and devices when the conformance should be proven. The applicability of this document to a TCN implementation allows for individual conformance checking of the implementation itself, and is a pre-requisite for further interoperability checking between different TCN implementations.

ČSN ETSI EN 300 175-3 V2.9.1 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 Medium Access Control (MAC) layer. The MAC layer is part 3 of the DECT Common Interface standard and layer 2a of the DECT protocol stack. It specifies three groups of MAC services: - the broadcast message control service; - the connectionless message control service; and - the multi-bearer control service. It also specifies the logical channels that are used by the above mentioned services, and how they are multiplexed and mapped into the Service Data Units (SDUs) that are exchanged with the Physical Layer (PHL). 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.

ČSN ETSI EN 300 175-5 V2.9.1 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.

ČSN ETSI EN 300 176-2 V2.4.1 The present document specifies the tests applicable to all Digital Enhanced Cordless Telecommunications (DECT) equipment accessing any DECT frequency band (including applicable IMT-2000 frequency bands) and the tests applicable to DECT speech and audio transmission using any of the codecs and any of the audio specifications described in ETSI EN 300 175-8 [8]. The aims of the present document are to ensure: - efficient use of frequency spectrum; - no harm done to any connected network and its services; - no harm done to other radio networks and services; - no harm done to other DECT equipment or its services; - interworking of terminal equipment via any public telecommunications network, including the ISDN/PSTN network and the Internet, through testing those provisions of ETSI EN 300 175-1 [1] to ETSI EN 300 175-8 [8] which are relevant to these aims. The tests of ETSI EN 300 176 are split into two parts: - part 1 [9] covers testing of radio frequency parameters, security elements and those DECT protocols that facilitate the radio frequency tests and efficient use of frequency spectrum; - part 2 (the present document) describes testing of speech and audio requirements between network interface and DECT PT, or between a DECT CI air interface and alternatively a DECT PT or FT. The present document is not applicable to terminal equipment specially designed for the disabled (e.g. with amplification of received speech as an aid for the hard of hearing). DECT terminal equipment consists of the following elements: a) Fixed Part (FP); b) Portable Part (PP); c) Cordless Terminal Adapter (CTA); d) Wireless Relay Stations (WRS) (FP and PP combined). The present document is structured to allow tests of either: a) the FP and PP together; or b) the FP and PP as separate items. Where the DECT FP is connected to a PSTN, and there are any peculiarities in the requirements for voice telephony, these will be accommodated within the FP.

ČSN EN IEC 61131-9 ed. 2 (18 7050) This part of IEC 61131 specifies a single-drop digital communication interface technology for small sensors and actuators SDCI (commonly known as IO-Link™ ), which extends the traditional digital input and digital output interfaces as defined in IEC 61131-2 towards a point-to-point communication link for the exchange of complex data in both directions. This technology also enables the transfer of parameters to Devices and the delivery of identification and diagnostic information from the Devices to the automation system. This technology is mainly intended for use with simple sensors and actuators in factory automation, which include small and cost-effective microcontrollers. This document specifies the SDCI communication services and protocol (physical layer, data link layer and application layer in accordance with the ISO/OSI reference model) for both SDCI Masters and Devices.
