Abstract

1402488 Automatic exchange systems PLESSEYCOLtd 8 Nov 1973 [23 Feb 1973] 8922/73 Heading H4K In an exchange comprising a calling number generator G which, on initiation of a call by a subscriber, generates the number of the calling subscriber, assigns a register R to the call and registers the generated number in the calling store SG of the assigned register, and control equipment C which establishes a signalling path through a switching network N to the called store SD of the assigned register via a first type of supervisory S1 if the digits registered in the called store indicate that a second type of supervisory S2 is required control C connects the assigned register to the calling line circuit L via a by-pass link K while another signalling path is being established through the network N to a supervisory of the second type.
