Abstract:
1. An arrangement for producing a time interval between a first data frame and a second data frame, said arrangement including: a memory device arranged to buffer digital data that contains said first data frame, said second data frame, and digital stuffing data, a reading unit arranged to read said digital data from said memory device in a chronological reading order defined by information connected to said digital data, a calculation unit that is arranged to define a bit quantity of said digital stuffing data on the basis of a target length of said time interval according to a pre-determined rule, and a write unit that is arranged to write said bit quantity of said digital stuffing data in said memory device, so that said digital stuffing data is in said chronological reading order located as succeeding said first data frame and as preceding said second data frame, wherein the pre-determined rule is one of the following three equations: where TB is the bit quantity of said digital stuffing data, St is a data transmission rate, DP is the target length of said time interval, V is a pre-determined constant, and F is a pre-determined function, the value of which is defined on the basis of at least one of the following: a size of said first data frame and a size of said second data frame.
