Abstract
A transmission system for telecopying and for distribution of in-house mail incorporates an electronic transmission system formed as a ring circuit, interconnecting a number of terminal devices which can transmit and receive messages. Information originating with the terminal devices circulates in the ring circuit until it reaches the receiver for which it is addressed, at which time it is erased. The transmission system may be employed to transmit the same information to a plurality of terminals, or to deliver a plurality of copies of the document to one terminal.
