Abstract
A method for establishing a digital communication link between an originating subscriber terminal and at least one called subscriber terminal, said method being better adapted to the transmission bandwidth used by a subscriber, has the following steps: First, a provisional link at a standard transmission rate from the originating subscriber terminal to the called subscriber is requested from a switching center. That provisional link is then established by the switching center. Next, a new, lower value for the transmission rate is selected by the originating subscriber terminal. That new value is then agreed upon with the switching center. Lastly, the latter switches the transmission rate of the provisional link over to the new, lower value, thus completing establishment of the communication link. The invention can advantageously be used in a telecommunications network, which for example operates according to the ISDN standard, to economize on transmission capacity and reduce call charges.
