Question

When was the Telex service started?
A. 1926
B. 1930
C. 1963
D. 1965

Answer 1

Hint: The Telex network was a public network based on teleprinters which were the same as a telephone network. Telex was a very significant service in the post World war II periods.

Complete answer: The Telex was one of the most significant services which could send written messages electronically. The Telex was started in Germany in 1926. It became an operational teleprinter service in 1933. It became very popular in Europe and around the world. The name ‘Telex’ is the name of the network and not the teleprinters. Teleprinters developed from telegraph systems and also used binary signals. Telex was the first common medium which used standard signalling techniques and the operation was conducted as standards set by the International Telecommunication Union. The system was able to deliver 50 baud of 66 words per minute. Customers were able to send messages to one another on any telex exchange. The telex service came towards a decline and was replaced by modems and phone lines. The communication could be made by entering the designated call number of the designated subscriber. The designated subscriber responds using a code to verify the identity and the communication is opened.
Therefore, option A is correct.

Note: When the message reaches its destination, it is either printed immediately or stored for printing or a display monitor. Telex systems continued to function by private corporations in the US while in the other countries, the operation was undertaken by government agencies who were responsible for telegram, postal services, etc.
