ABSTRACT:
Method and apparatus for individually monitoring transmission sections of a communication transmission link, whereby auxiliary signals serving the purpose of bit error recognition are newly-calculated when they are regenerated. In order to be able to check monitoring circuits under remote control, the auxiliary signals in a test mode are formed in a manner different from that in a normal monitoring mode. The reception of a prescribed plurality of such auxiliary signals serves as criterion for the test mode.
