method for operational monitoring of digital transmission routes

摘要

it is a method for operational monitoring of digital fiber optic transmission routes is given, in which the bits and test bits obtained together with items of data to be gathered and transmitted to the respective items of data to be gathered at the same position are added.at the receiving end will test bits obtained in the same manner as on the transmission side is generated and the data stream withdrawn from the test bits obtained are compared. the evaluation of the actual information independent test bits obtained at the receiving end, leads to the identification of the bit error rate testing.
