Abstract
1,089,042. Multipling arrangements. INTERNATIONAL STANDARD ELECTRIC CORPORATION. July 9, 1965 [July 10, 1964], No. 29208/65. Heading H1L. [Also in Division H4K. In an exchange system having some subscribers lines which carry heavy traffic and others which carry relatively light traffic, the former are multipled on to all the selectors of a final selector whilst the latter are multipled on to some only of the selectors. As described the final selector is a crossbar multiswitch (MT1) of which the selectors (verticals ST1 &c.) are connectable to some full multiples leading to heavy traffic lines (AB1) and to some split multiples leading to light traffic lines (such as AB2 and AB3). The multipling on a switch providing 100 outlets with only fourteen select bars is described with reference to Fig. 2 (not shown).
