Electrical communications system
First Claim
1. A communications system for electrical signals, comprising in combination:
- a plurality of input signal sources generating respective electrical communications signals;
first memory means coupled to at least one of said plurality of input signal sources and including control means for controlling the inputting and storing of said electrical communications signals in said first memory means and upon command thereafter outputting said electrical communications signals therefrom;
first energy type transmitter means coupled to said first memory means and being responsive to the electrical communications signals outputted from said first memory means to generate a modulated signal including said electrical communications signals and coupling said carrier signal to a first energy type communications link;
first energy type receiver means coupled to said first energy type communications link and being responsive to said carrier signal to demodulate the carrier signal to reproduce said electrical communications signals;
second memory means coupled to said first energy type receiver means and including control means for controlling the inputting and storing of said electrical communications signals in said second memory means and upon another command, thereafter outputting the stored electrical communications signals from said second memory means;
second energy type transmitter means coupled to said second memory means and being responsive to said electrical signals outputted from said second memory means to generate a modulated carrier signal including said electrical communications signals and coupling said carrier signal to a second energy type communications link;
second energy type receiver means coupled to said second energy type communications link and being responsive to said last recited carrier signal to demodulate the carrier signal to reproduce said electrical communications signals;
third memory means coupled to said second energy type receiver means and including control means for controlling the inputting and storing of said communications signals into said third memory means and upon yet another command thereafter outputting the data from said third memory means; and
at least one utilization device coupled to said third memory means and being responsive to the electrical communications signals outputted therefrom to perform a desired task depending upon the nature of said electrical communications signals fed thereto.

Abstract
Disclosed is a system for communicating electrical signals, digital and/or analog, from one location to another first over an RF communications link and then secondly over an optical communications link. A first digital memory is included on the transmitter side of the RF communications link so that a plurality of fixed or portable signal sources can feed data thereto in a desired sequence for subsequent transmission upon demand first to at least one second or interim digital memory at the end of the RF communications link and then to at least one third digital memory at the end of the optical communications link. The third memory is located in a terminal unit, fixed or portable, which is adapted to feed the data transmitted thereto to one or more utilization devices.
