Abstract

1,083,312. Intercommunication systems. SHIPTON ELECTRONICS Ltd. March 9, 1964 [March 11, 1963], No. 9540/63. Heading H4K. In a system comprising a number of speech lines and a common signalling line, with a binary counter at each station, the counter at a calling station is set by key actuation to the complement of the number to be sent and a pulse generator operates to send pulses over the signalling line until the pre-set counter is stepped to zero, the circuits being such that a calling signal is then given at the wanted station. An idle speech line is selected at that station, and the instruments of both stations are connected thereto, the selected line being marked busy.
