Abstract
1,044,601. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. May 14, 1965 [May 15, 1964], No. 20429/65. Heading H4K. In a system having primary and secondary switching stages EP, ES each arranged in sections such as SP1, SP2; SS1, SS2 in which direct links such as mpd1, mpd2 connect each primary section with each secondary section. each primary section includes both regular selectors CV, DV and overflow or entraide selectors ECV, EDV, the latter being connected to the regular selectors of other primary sections by links such as mpe1, mpe2. Assuming that an inlet ent1 requires to be connected to a marked outlet st, the first-choice route is over the direct link mpd1. If that is busy, the entraide link mpe1 is selected and is extended over the entraide selector EDV of the section SP2 to the entraide link mse2 if available, or else over the regular link mpd2 to the secondary stage SS1. The system is a development of that described in Electrical Communication, Vol. 38, March 1963, in a paper entitled 1000B Pentaconta Crossbar Switching System.
