Abstract

967,253. Automatic exchange systems. PYE Ltd. May 24, 1961 [May 25, 1960], No. 18471/60. Drawings to Specification. Heading H4K. A register circuit for a two-digit automatic exchange comprises a first cold cathode counter operable to the first digit to route the second digit to one of a plurality of second counters, one of which is provided for each first digit. The register being provided with a selfextinguishing tube which is ignited via a timeconstant circuit from the first counting tube to clear down the register in the event of receipt of a single pulse (e.g. either a spurious pulse or a pulse due to the digit 1 being dialled). A control tube for extinguishing the tubes of the first counter is also instrumental in providing busy tone. The description is substantially identical with part of Specification 967,252.
