Claim 9

A method for in-service monitoring the accuracy of electronic data transmitted over a communication channel or telemetry link comprising the steps of: a. generating in a first site first error codes, one each for each unit of data (i.e. block) being transmitted; b. generating in a second site second error codes, one each for each unit of data (i.e. block) being received; c. transmitting said second error codes in said second site to said first site; d. comparing said second error codes with said first error codes; and, e. determining if the comparison is synchronized to the same unit of data so that the first error code in said first site is compared for the same unit of data to the second error code transmitted from said second site to said first site.
