Push-to-type Operation

Push-to-type operation: In telegraph or data transmission systems, that method of communication in which the operator at a station must keep a switch operated in order to send messages. Note 1: Push-to-type operation is used in radio systems where the same frequency is employed for transmission and reception. Note 2: Push-to-type operation is a derivative form of transmission and may be used in simplex, half-duplex, or duplex operation. Synonym press-to-type operation. Source: From Federal Standard 1037C and from MIL-STD-188
