Abstract

1524028 Automatic exchange systems STANDARD TELEPHONES & CABLES Ltd 14 Oct 1975 [22 Oct 1974] 45604/74 Heading H4K A stored program controlled microprocessor is adapted to function as an impulse repertory dialler. As described under the control of a program in a read only memory ROM and a keyboard, a microprocessor CPU effects reading out the directory number of a selected subscriber from a non- volatile number store EAROM into a random access store RAM used to provide temporary storage during outpulsing. The keyboard has two key banks one used to select repertory subscribers and the other used for digit by digit non-repertory dialling. A monitor speaker may be employed to allow the subscriber to follow the progress of the call until it is transferred to the handset on lifting the latter upon completion of dialling. [GB1524028A]
