Title: Improvements relating to switching systems employing co-ordinate switching arrangements of the cross-point type
Inventor: DELLER WILLIAM BERNARD
IPC: H03K17/70
Filed: 1960-11-04
Abstract: 945,374. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 13, 1961 [Nov. 4, 1960], No. 37989/60. Heading H4K. In a system involving a number of switching stages of the two co-ordinate type and using four zone diodes as the cross-point switches, a pair of positive and negative going pulses, which together are sufficient to breakdown such a diode, are applied to the appropriate row and column conductors of each stage in succession, one of these pulses persisting so as to temporarily hold a diode operated (and all previously operated diodes in the chosen path) until the succeeding pulses applied to the next stage have occurred, the interconnections between stages including individual rectifiers so poled as to permit flow of the holding current but to prevent said pulses being applied to adjacent stages. A known system incorporating four zone diodes is described with reference to Figs. 1 and 2 (not, shown), and it is shown that in the absence of the above-mentioned rectifiers, voltages can be obtained which may lead to the inadvertent reverse breakdown of cross-point diodes in adjacent switching stages. In setting up a connection between a calling subscriber's line circuit S and a supervisory circuit L, " long " positive (2) and " short " negative (1) pulses VT (Fig. 4), are applied from pulse sources PC, 1 and 2 (Fig. 3), to appropriate row and column conductors in the first switching stage SW1 whereby diode CP1 is operated. Diode CP2 operates to the succeeding pulses 3, 4 (Fig. 4), applied in stage SW2 (these pulses being prevented from reaching SW1 and SW3 by rectifiers D3 and D4) and diode CP1 (and CP2) now holds to the long positive pulse 4. In response to extension of the path to circuit L, transistor VT1 conducts and passes a holding current for the operated diodes. Fig. 5 (not shown), depicts a method whereby an operator may break in on an existing connection by using an identical switching stage multipled to the conductors of stage SW1 on the side remote from the subscriber's lines. Specifications 818,862 and 945,378 are referred to.
