Under Datex-S, Deutsche Telekom had offered business communications services via satellite. Applications offered included file transfer, image-supported office communications, CAD/ CAM applications, LAN interconnection and backup services.
In 1993, the Metered Channel System( MCS) service was introduced. It offers pan-European transparent dial-up connections with data rates from 64 kbit/s to 2 Mbit/s. Datex-S is of particular interest for LAN interconnection of multiple sites via routers. The user needs a customer station Network Access Terminal( NAT) installed by Telekom at each relevant location.
With Datex-S, companies can also connect branch offices to the corporate network in Eastern Europe, where no network infrastructure is yet available. Datex-S complements Deutsche Telekom's existing service offering in the form of satellite transmission:
- Skynet Packet and Skynet Cast are Telekom services for data connections and interactive data traffic.
- Skynet Line is a service for digital national and international fixed connections via satellite from 64 kbit/s to 2 Mbit/s; the service was formerly known as FVSat (fixed connections via satellite).
