Abstract
A digital data transmission system includes a transmitting party, a receiving party, a non-transparent circuit-switched data connection between the transmitting and receiving parties, a control element for changing the data transmission capacity of the data connection, and a sliding-window data flow control protocol where the number of transmitted data frames to which the transmitting party has not received an acknowledgement from the receiving party is not allowed to exceed the size of the sliding window. The transmitting and receiving parties are arranged to change the size of the sliding window when one or both of them receive information from the control element on a change in the data transmission capacity of the data connection.
