Method and system for monitoring a receiving circuit module and controlling switching to a back-up receiving circuit module at a local collection facility from a remote facility

摘要

A system and method for remotely collecting signals includes a local collection facility comprising a plurality of primary receiving circuit modules comprising a first receiving circuit module. The first receiving circuit module receives a first channel signal and forms a first encoded signal. The system further includes a remote facility having a multiplexer, and a router routing the first encoded signal to the multiplexer. The remote facility generates an output signal in response to the first encoded signal. A monitoring system receives an error signal from the first receiving circuit module. The router routes the error signal of the first receiving circuit module to the monitoring system. The system also includes a back-up receiving circuit module. The router routes the first channel signal to the back-up receiving circuit module to form a second encoded signal. The monitoring system monitors the second encoded signal. The router routes the second encoded signal at the local collection facility to the multiplexer at the remote facility in response to monitoring the second encoded signal. The remote facility forms the output signal in response to the second encoded signal.
