Abstract

524,003. Automatic exchange systems. POLLAK. J. E. (Associated Telephone & Telegraph Co.). Jan. 19, 1939, No. 1899. Drawings to Specification. [Class 40 (iv)] In a system having arrangements for printing information relating to calls, a switching device in response to a number of digits takes up a position representing the zone or exchange of the wanted party wherein it selects leads individual to letter magnets of a printing device to print the zone or exchange name instead of numbers. The system described is the same as that described in Specifications 516,408, 516,409 except for modifications enabling zone-name printing to be effected. In the printer-controller, the relay registers in which the two zone digits are stored are used to mark a bi-directional switch which over three wipers prepares the selection of three leads to letter magnets in the printer. As the printer control switch (OP2) in the aforesaid Specification makes provision only for two zone digits whereas three letters are now required, the position in DP2 used for printing a star (request for information) is used for the extra letter and the star is printed under the control of an additional relay.. If three letters do not identify the zone, discrimination is effected by the first zone digit to cause a fourth or further letters to be printed instead of the third dialled digit, a fourth or further wipers of the bi-directional switch being used for this purpose. As an alternative to the bidirectional switch, a hunting switch may be positioned according to a combination marking applied by a number of single motion switches set in accordance with the zone digits. The Provisional Specification describes also the transmission from the originating system translator of the exchange designation in a letter code.
