| 3 | 2 | laforge | _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, but (at least) [[Telex]], [[CSPDN__Datex-L]] and [[Teletex]], the network based on EDS technology was also called IDN (Integriertes Daten Netz). |

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. |
