Abstract

1,069,246. Electric selective signalling. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Dec. 23, 1965 [Dec. 24, 1964], No. 52515/64. Heading G4H. [Also in Division H4] A dialling pulse generator, Fig. 2 (not shown), comprises means for passing a number of dialling pulses to one of a number of lines under the control of a binary input signal. The input signal comprises a 3-bit section which selects one of eight lines by means of gates, and a 4-bit section which represents the digit to be dialled. Initially a long pulse is sent on the selected line. When this ceases clock pulses, i.e. dialling pulses, are passed over the line and also to a binary counter. The counter is set by the 4-bit section and is counted down to zero by the clock pulses, whereupon no further clock pulses are transmitted.
