Abstract

981,339. Automatic exchange systems. SIEMENS & HALSKE A.G. June 9, 1961 [June 10, 1960], No. 20936/61. Heading H4K. A time division multiplex switching system having individual circulating systems which store the calling and called subscribers' identities also contains further circulating stores for giving further information about the subscribers, e.g. that they are receiving dial tone, ringing current or busy tone. As shown subscribers are connected to each other by inserting pulses of the same phase into appropriate combinations of delay line stores Ua (calling subscriber) and Ub (called subscriber) to open gates such as S1 . . . Sx to affect communication over the common multiplex highway SM. Dial tone GW, ringing tone GR, and busy tone GB may be connected up by inserting appropriately phased pulses in stores td1 . . . 3 to open gates gw, gr, gb in phase with a subscriber's gate. Digit receivers Z1 . . . Zi may be connected up by inserting the subscriber's phase into appropriate combinations of stores Uc. Stores such as Ua, Ub, Uc may have an output such as n of Uc indicating all busy phases in the respective combinations of stores. Specifications 981,335, 981,336, 981,337 and 981,338 are referred to.
