h1. (Siemens) Siemens EDS _Siemens EDS_ is the type of digital exchange equipment which was used to build the German [[CSPDN__Datex-L|DATEX-L]] CSPDN (circuits switched public data network). It was also used as backbone to migrate [[Telex]] subscribers away from the older electromechanical switches. Since it didn't just serve one data technology, We currently don't yet know much about it, but (at least) [[Telex]], [[CSPDN__Datex-L]] hopefully some related books and [[Teletex]], articles will arrive within the network based on EDS technology was also called IDN (Integriertes Daten Netz). EDS is the result of a development collaboration between the two manufacturers Siemens AT and SEL (Standard Elektronik Lorenz AG) Early design started in 1965 by consultation of [[Deutsche_Bundespost]] with the industry, and subsequent testing, the first EDS exchange wnet into production in 1975 in Mannheim. It was supposedly the first world-wide fully electronic circuit-switched data exchange supporting up to 16,000 subscribers via time division multiplex. By 1978, more than 60% of all Telex and Datex subscribers had been migrated over to the EDS. h2. DVST-L h2. DUST next few weeks.
