METHOD FOR TRANSMITTING USER DATA THAT CAN BE ALLOCATED TO DIFFERENT APPLICATIONS

摘要

The invention relates to a method for transmitting user data, that can be allocated to different applications, between the A-side and the B-side of an ATM transmission path using an ATM connection established by signalization. The data allocated to the individual applications is transmitted in the substructures that can be allocated to the applications within an ATM adaptation layer frame containing several ATM cells. To this end, the A-side and the B-side allocation of the substructures of an ATM adaptation layer frame is determined by signalization in the signalization phase. Additional information such as the number of ATM cells contained in an ATM adaptation layer frame or data indicating whether the individual substructures have the same size can also be determined by signalization.
