Abstract

1,103,514. Automatic exchange systems. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 14 May, 1965 [16 May, 1964], No. 20450/65. Heading H4K. A small exchange which may be transportable is provided with two multi-armature relay selectors OHS1, 2 of the kind described in Specification 891,873 which accommodate 32 subscribers' lines in positions 5 . . . 12 of 4 levels a1 ... a4, b1 ... b4 (the latter not shown). Positions 1. . . 4 are connected to link circuits VS1, and each selector has also an auxiliary level h for testing purposes. Assuming that a subscriber Tln wishes to call Tln 47 for example, a link circuit VS1 is taken into use and an associated register receives the tens and units digits and effects the closure of contact springs 4 and 11 of one of the selectors. Potential from a test device Pr is thereby connected to resistance R11. If the wanted subscriber is already connected to the other selector, diode D11 is blocked and a busy test device M responds. Otherwise the connection is completed normally.
