ABSTRACT:
A monitoring system having a plurality of receivers connected to at least one other receiver such that data can be transmitted from a primary receiver to a backup receiver if a data path to an automation computer or to its printer is down. The system programs a primary data path and at least one backup data path. The system detects an error in the primary data path and determines if a backup receiver's data path is operational. The system automatically transmits data received by a primary receiver to a pre-selected backup receiver based upon an error flag. This allows for each receiver to process calls even though its primary path to the automation system or printer is down or malfunctioning.
