3U HOLDING AG: 3U TELECOM puts next-generation network (NGN) into operation

Marburg (pta013/19.03.2019/08:00) - -
* Interconnects to Deutsche Telekom master test procedures
* TC business at 3U poised for gains in market shares and rise in profitability

All the telecommunications companies within the Group of 3U HOLDING AG (ISIN DE0005167902) have now successfully converted all interconnects to Deutsche Telekom to an NGN interconnection. With the technological development in modern ICT networks, the circuit-switched (PSTN/ISDN) technology in telecommunications networks is gradually being supplemented or replaced by IP technology, so-called "next-generation networks" (NGN). Voice transmission in an NGN takes place via Internet Protocol (Voice over IP (VoIP)).

Interconnects serve to connect and transmit calls between different networks. VoIP, telephony via Internet Protocol, is the telecommunications technology that will in future be used exclusively in German and international fixed line networks. Conversion was preceded by a multi-stage test procedure that the 3U networks successfully mastered in which Deutsche Telekom and 3U tested the shared NGN interconnections in complex test procedures with regard to compatibility, interoperability and settlement quality.

As well as the conversion to IP, the NGN interconnects to Deutsche Telekom and other reputable network operators also serve to facilitate a considerable expansion of network capacity. This is enabling 3U to create a solid and expandable basis for its six connection networks (call-by-call and preselect services) and three subscriber networks in order to continue to hold its own successfully in the ongoing fiercely competitive market environment. The interconnects to all other national and international network operators are also to be fully converted to NGN by the end of 2019.

As a telecommunications service provider, 3U offers its customers reliable and secure telephone conversations at a leading price/performance ratio. This high-quality service is based on decades of experience, state-of-the-art technology and infrastructure and extremely efficient procurement of third-party services. 3U expects to continue to gain market shares in the declining market for fixed line telephony in the future and to increase its profitability.
