Abstract
A digital data transfer system having information read-out from a first memory to a user device through temporary storage in an intermediate second memory. The system includes a measuring device which determines the extent to which the second memory is filled with information read-out from the first memory while the information is being transferred to the user device from the second memory. Upon detecting a predetermined first degree of filling, the measuring device produces a first alarm signal which, after a given first delay, is used to temporarily block further read-out of information from the first memory. Afer a predetermined second degree of filling of the second memory in then detected, the measuring device produces a second alarm signal which, after a given second delay, is used to resume the read-out of information from the first memory to the second memory.
