h1. Telex
Telex was a network of _Teleprinters_. The network was similar to the PSTN telephony network, but independent/separate from it. Telex interconnected teleprinters via a switched network where subscribers can dial other subscribers via signaling, just like in the telephony network. This was different from earlier poin-to-point teleprinters without a switched network before.
Telex began in Germany as a research and development program in 1926. The operational service was introduced in 1933. It declined in the 1980 as [[Telefax]] became availabel and popular.
