Telex is one of the most
important medium of electronic communication. Telex is the name given by the
people of the postal department to a tele-printer whereby written messages can
be communicated from one place to another with the help of a machine. It is
used to transmit .information with the help of tele-printer through exchange
system. Post and telegram departments provide services to the telex users under
this exchange system. The user of telex machine has to collect the specific
telex number from the nearby post and telegraph office. Information .can be
transmitted by the telex through exchange as a particular telephone set is
connected with another exchange system.
The tele-printer has two parts : (i) Key board transmitter and (ii) receiver. When a message is to be sent, the typist presses a button, waits for dial tone, dials the number desired and if the number is contacted types the message. The message as typed in the originating office is typed on a strip of paper at the receiver's end. This is one of the quickest and most accurate methods of transmitting written communication.
