telex
Pre-fax transmission
Telex was a communication system that transmitted typed messages between machines over telephone lines, dominant from the mid-20th century until fax and email displaced it.
A telex is also a message sent through this system: We received a telex from the London office.
As a verb, to telex is to send such a message.
The technology is now largely obsolete.
