System and method for remotely restoring inoperative data communications
First Claim
1. A system for remotely restoring inoperative data communications, comprising:
- a first communications unit comprising;
a data communications transmitting unit;
a second communications unit comprising;
a data communications receiving unit;
a transmission medium coupled to said data communications transmitting unit and said data communications receiving unit;
said first communications unit further comprising;
a first logic circuit coupled to said data communications transmitting unit, said first logic circuit operable to generate a predetermined sequence of signals that key an output of said data communications transmitting unit on and off to send said predetermined sequence of signals over said transmission medium; and
said second communications unit further comprising;
a second logic circuit coupled to said data communications receiving unit, said second logic circuit configured to recognize said predetermined sequence of signals as indicative of inoperability of said second communications unit and output a signal to attempt to restore said second communications unit, if said predetermined sequence of signals is detected at said data communications receiving unit.

Abstract
A method for remotely restoring inoperative data communications is disclosed. The method includes generating a predetermined sequence of signals at a first Communications unit. The method further includes keying an output of a transmitter on and off at the first communications unit with the predetermined sequence of signals and conveying a transmission of the predetermined sequence of signals to a second communications unit. The method also includes recognizing the predetermined sequence of signals at the second communications unit as indicative of inoperability of the second communications unit and, responsive to the recognized predetermined sequence of signals, outputting a signal to attempt to restore inoperative data communications at said second communications unit.
