German long-distance cable company
The Deutsche Fernkabel-Gesellschaft mbH (DFKG) was a German telecommunications company .
history
Foundation and development until 1945
The company was founded with the aim of building the underground telecommunications network in the German Reich on April 7, 1921 with its headquarters in Berlin-Charlottenburg by the shareholders of the German Reich ( Reichspost / Reichspostministerium ), Siemens & Halske , AEG , Felten & Guilleaume and three smaller cable producers .
The aim was to enable the uniform construction of the German long-distance telecommunications network using all technical advances. The DFKG was able to apply all patents , property rights and experience acquired by the shareholders in the execution of its work. Conversely, all of the company's own patents, property rights and experience were available to the shareholders.
The purpose of the company was to form a cartel consisting of the client (ministry) and suppliers (cable producers) for the procurement of long-distance cables as well as for their laying and guarantee. At a time when the procurement markets were isolated nationally, the protection of local industry was an industrial policy goal, and cartels were accepted and widespread in industry, the ministry that required the establishment wanted to limit its dependence on Siemens & Halske, by granting the market leader a fixed market share. Siemens owned the major patents for Pupin cables . The industrial base for cable production was expanded by bringing three smaller cable manufacturers, without patents, to the company.
After Austria was annexed in 1938, the Austrian cable companies became involved in the DFKG. In 1943 the attempt to extend the model to the entire German sphere of influence within the framework of an international long-distance cable company failed.
From 1921 to 1943, the DFKG published the specialist journal "European Telephony" and its supplement "European Telephone Atlas".
Development after 1945
After the Second World War , the operational headquarters were relocated to Rastatt . At the beginning of the 1970s, the following were shareholders in the GmbH :
- German Federal Post Office
- Siemens AG , Berlin and Munich
- Telefunken GmbH, Berlin
- Felten & Guilleaume Carlswerk AG, Cologne
- Cable and metal works Gutehoffnungshütte AG, Hanover
- Süddeutsche Kabelwerke , branch of the Vereinigte Deutsche Metallwerke AG, Mannheim
- United Wire and Cable Works AG, Berlin and Duisburg
- Kabelwerk Rheydt AG, Rheydt
- Wiener Kabel- und Metallwerke AG , Vienna
- Standard Elektrik Lorenz AG, Stuttgart
- Kabel- und Metallwerke Neumeyer GmbH, Nuremberg.
The work program of the DFKG included participation in the exploration of the long-distance cable systems, the laying, assembly and electrical balancing of the cables, as well as the installation of compressed gas protection devices in-house. The DFKG was responsible for ensuring compliance with the mandatory values required by the Deutsche Bundespost in terms of civil engineering, electrical and pneumatic equipment. A business contract and statute ensured close cooperation between the Bundespost and the DFKG.
From 1986 the Deutsche Bundespost , later the Deutsche Telekom AG, was the sole shareholder, as the European Commission had assessed the company as a cartel . After 1989 it was partially relocated back to Berlin.
From February 1, 1995, the company was called DeTeLine Deutsche Telekom Kommunikationnetze GmbH.
In 2003 the company merged with T-Data Ges. Für Datenkommunikation mbH to form Network Projects & Services GmbH. In 2005 this merged with T-Systems Business Services GmbH and Vivento Technical Services GmbH. Vivento Technical Services GmbH was sold on January 1, 2008 to Nokia Siemens Networks Services GmbH & Co. KG, a joint venture between Siemens and Nokia .
