Modular configurable communications recorder

Abstract

A multichannel communications recorder or logger having the capability to display channel activity, failsafe back-up capability, a unique identification code with provision for changing such code, and apparatus for securing access to the communications recorder. The recorder is formed from modular elements which may be configured into a large number of selectable configurations. Possible configurations include provision of back-up record decks and back-up record amplifiers, as well as various selectable auxiliary components. In each configuration one or more record decks is controlled by a control module which includes a system control microprocessor and a CRT control microprocessor, which, in turn, controls a user interface including a CRT for displaying pages of control information and a plurality of softkeys. Control is provided by a user selecting to implement functions defined in accordance with a particular page displayed or to move to another page in a hierarchy of pages using the softkeys, and entering the necessary information through a keypad; also provided. Access to various pages is controlled by various levels of passwords with the highest level being used by a service person to input information defining selected configurations and to run diagnostic tests and lower levels being provided to users of the system. Because of the need to provide physical security for recorded tapes, each tape deck is secured by an electromechanical lock, which operates under system control.
