Videotex and telescopy terminal with automatic reception

Abstract

Abstract The videotex terminal (1) comprises a first interface circuit (13, 15) configured for requesting and receiving pages of characters originating from a server centre, and a second interface circuit (212, 25) provided with an output linked to a printer (24) for printing stationary images in reply to graphics data of telecopy type. It also comprises a circuit (21) for detecting a call, arranged on the telephone line (3) to which it is connected, a change-over switch (213) for connecting the line to the second interface circuit, in reply to a detected call, a circuit (29), linked to the output of the second interface circuit, for detecting a graphics data transmission request and for controlling, if appropriate, the printing of these graphics data by the printer (24), and if not, the connecting of the line (3) to the first interface circuit, and a circuit (17), linked to the output of the first interface circuit, for detecting a character pages transmission request and for controlling, if appropriate, their receipt, and, if not, an alarm (27) so as to warn an operator. The terminal permits automatic reception of videotex and telecopy data with a single telephone line. <IMAGE>
