Telex is a telecommunication service that provides text-based message exchange over ... Telex began in Germany as a research and development program in 1926 that ...
Telex (telegraph exchange) was a public switched network of teleprinters. It used rotary-telephone-style pulse dialling for automatic routing through the network. It initially used the Baudot code for messages. Telex development began in Germany in 1926, becoming an operational service in 1933 run by the Reichspost (the German imperial postal ...
Telex machines first performed rotary-telephone-style pulse dialling for circuit switching, and then sent data by ITA2. This "type A" Telex routing functionally automated message routing. The first wide-coverage Telex network was implemented in Germany during the 1930s [67] as a network used to communicate within the government.
In the early 1980s, the imminent replacement of the Telex service seemed likely. A new Teletex service was introduced in Germany in 1981. It was expected that this would replace the telex service over time. Hasler used Teletex/Telex converters with the T203 for intercommunication between the new Teletex service and Telex.
The Overseas radio reception center Lüchow (German: Übersee- Funkempfangsstelle Lüchow (ÜFESt or ÜEFuSt)) was one of the large radio reception centers of the German Federal Post Office for civil telecommunications use between 1948 and 1987. It was used to handle teletype, telegram and telephone services worldwide via shortwave radio.
ADFGVX cipher. In cryptography, the ADFGVX cipher was a manually applied field cipher used by the Imperial German Army during World War I. It was used to transmit messages secretly using wireless telegraphy. ADFGVX was in fact an extension of an earlier cipher called ADFGX which was first used on 1 March 1918 on the German Western Front.
ARQ-M. ARQ-M, short for Automatic Repeat reQuest, Multiplex, is a radio telegraphy protocol used to reliably forward telex messages over partially reliable radio links. [1] It is a low-speed system designed to match the performance of landline telex systems and allow those messages to be forwarded over long distances using shortwave radios.
C. Lorenz AG (1880–1958) was a German electrical and electronics firm primarily located in Berlin. It innovated, developed, and marketed products for electric lighting, telegraphy, telephony, radar, and radio. It was acquired by ITT in 1930 and became part of the newly founded company Standard Elektrik Lorenz (SEL) Stuttgart in 1958, when it ...
