Abstract:
1. Data transmission method in which a number of data words are transmitted in a data frame with time slots according to a TDM method, corresponding to time division multiplex, from a transmitting unit to a receiving unit, wherein a specific number of output buffers are provided for the outputting of the data frames, said output buffers alternately being used for data outputting, said method including the steps of employing error detection by inserting a number of marking bits at a position within an unused section of at least one specific data word of the data frame thereby establishing a first pattern of marking bits, and changing the pattern of the marking bits to create at least a second pattern from data frame to data frame in a defined sequence, wherein the defined sequence for changing the marking bits from data frame to data frame is determined by using said defined sequence to be the specific number of output buffers plus one.
