Abstract
Abstract A central processor unit (CPU) is used as a control element in an automatic telephone system. Certain other elements of the telephone system and peripheral devices thereof assigned various priority levels call for the services of the central processor unit by interrupting the central processor unit via an interrupt unit (IU). The central processor unit controls and supervises other elements of the telephone system and peripheral devices thereof via a multiplexer (MUX) and one or a plurality of data transfer units (DTU). The central processor unit comprises a data handling unit (DHU), a memory or storage module unit (SMU), a hardwired logic preloader (PRE), and a processor control unit (PCU) which, under control of a program stored in SMU, controls the various elements of the central processor unit and the associated telephone system. The data handling unit is a unit segregated from but cooperating with the processor control unit and includes segmented registers, shift control and character transfer gates for accommodating either words or characters. The processor control unit contains control logic and clock means which cooperate to stop the clock as required in the provision of asynchronous operation of the processor control unit with internal and external elements such as the shift control in the data handling unit, and the multiplexer unit. Communication between personnel and the central processor unit is effected by means of a master control panel (MCP) with manual controls and indication lamps thereon; and by means of keyboards via data transfer and multiplexer units.
