On March 14-16, Cabex 2023, the leading annual business event of the cable industry, took place at Expocentre Fairgrounds for the third time. By a good tradition, one of its key components was the scientific and technical conference "Cable Industry - Science. Technology. Production" organised by VNIIKP JSC, Elektrokabel Association and the Academy of Electrotechnical Sciences of the Russian Federation.

The eighth international scientific and technical conference of LLC "Saranskkabel-Optika", a member of Opticenergo Group of Companies, was held in Saransk on February, 16-17. The event took place in Technopark "Mordovia" and gathered about 130 participants from 25 cities of Russia, Belarus, Kazakhstan and Kyrgyzstan. This year conference motto was "Go forwards, don’t stand still!" Innovation, diversification, and import substitution are the three main principles on which the entire Opticenergo holding company bases its activities today.

MWC Barcelona 2023, traditionally organized by GSMA, was held again in Barcelona (Spain) from 27 February to 2 March 2023.

An overview of technological innovations in new  GPP Partner Project releases and European research projects applicable to the FRMCS ÌFuture Railway Mobile Communication SystemÍ is given. Considerations are given for the fastest possible deployment of the FRMCS system in the Russian Federation taking into account national requirements for railway communication.

Changes in telecommunication systems infrastructure that are caused by transition to new network technologies, a phased shift from channel switching technologies to packet switching ÌIP/MPLS/EthernetÍ, and developing of cellular systems ÌLTE and ÅGÍ, as well as ever increasing demands for accuracy and stability of timing signals also entail changes in approaches to solving the problems of frequency and timing support.
This paper describes problems which arise in modern and advanced telecommunication networks when synchronization signals are transmitted, as well as the topical technologies of their solution and directions of ongoing and future research.

The paper formulates the advantages of enterprises, which use digital twin technology, and develops recommendations for the sound decisions development on the implementation of this technology at the enterprise, including the choice of conceptual approach to create
digital twins. The general algorithm of the digital twin development at the enterprise is offered, prospects of development and application of digital twins are predicted.
