Abstract
1. Method for a series-connecting telemetry channels in both directions of transmission in a remote intermediate or terminal station of a digital transmission link, in which useful digital signals and the telemetry signals are transmitted via parallel channels, the telemetry signals consisting of individual messages which are formed by a terminal station and subsequently to that by the monitoring regenerative repeaters and by the regenerator of the other terminal station and the messages in each case containing at least one head signal, an information block and an end signal and a pointer to the position which begins with the cyclic transmission of the messages being inserted as start marker in the information block, characterized in that for the connecting-together, a first characteristic pulse sequence is inserted by the fault-locating terminal station into the information block of the message delivered by this terminal station, that the incoming messages are monitored for the occurrence of the first characteristic pulse sequence in the remote intermediate or terminal station and, when this is detected with the simultaneous occurrence of the start marker in the message of the fault-locating terminal station, the series-connection is switched from the end of one telemetry channel to the beginning of the other telemetry channel if the detecting intermediate or terminal station is not at the same time the fault-locating terminal station, and that the series-connecting is cancelled as soon as a second characteristic pulse sequence contained in the message of the fault-locating terminal station is detected.
