Beginning in the 1980s, the ability to conduct high-speed digital communication—particularly fax transmission—over nonleased dial-up telephone lines led to a decline in the use of telex. Western Union sold its Telex network to AT in 1990, before declaring bankruptcy in 1993.

How did a telex machine work?

A telex or teletype machine is similar to a typewriter. It is a printer that is connected to a telegraph-type machine that transmits data to other telex machines via telephone circuits using electrical signals. When you type your information on the keyboard, it is transferred onto a tape, which is coded.

How did the teletype work?

Teletype machines operate by the transmission of electrical “pulses” over wires from a sending unit to a receiving unit. Teletype machines “listen” to a code in which each letter or number is made by a combination of electrical pulses of equal length and automatically translate this code into printing.

A teletypewriter (TTY) is an input device that allows alphanumeric character to be typed in and sent, usually one at a time as they are typed, to a computer or a printer. The Basic Input/Output Operating System ( BIOS ) sends messages to a PC display using teletype mode. Most printers offer a teletype mode.

When did the telex system go out of use?

Its usage went into decline as the fax machine grew in popularity in the 1980s. The “telex” term refers to the network, and sometimes the teleprinters (as “telex machines”), although point-to-point teleprinter systems had been in use long before telex exchanges were built in the 1930s.

How did telex work with Western Union?

Telex users could send the same message to several places around the world at the same time, like email today, using the Western Union InfoMaster Computer. This involved transmitting the message via paper tape to the InfoMaster Computer (dial code 6111) and specifying the destination addresses for the single text.

What is the difference between a telex and a telephone system?

This differs from the analog telephone system, which used varying voltage to represent sound. For this reason, telex exchanges were entirely separate from the telephone system, with their own signalling standards, exchanges and system of “telex numbers” (the counterpart of telephone numbers).

How are Telex messages routed through telex networks?

Telex messages are routed by addressing them to a telex address, e.g., “14910 ERIC S”, where 14910 is the subscriber number, ERIC is an abbreviation for the subscriber’s name (in this case Telefonaktiebolaget L.M. Ericsson in Sweden) and S is the country code or location code.
