Patent ID: 8594058

Claim:
A method of dynamically adjusting the transmission capacity of a data transmission connection, comprising the steps of: at a network end node, receiving from a client via a first user network interface an incoming frame-structured time division multiplex signal carrying incoming timeslots, and a request data set, comprising for at least one incoming timeslot a corresponding subset, said request data subset having an identifier identifying an existing data transmission connection; and a status indicator indicating a status requested by said client for the corresponding incoming timeslot; if said status indicator indicates a request for adding said incoming timeslot to or removing said incoming timeslot from said data transmission connection, adjusting the transmission capacity of said data transmission connection, otherwise, if said status indicator indicates valid data in said incoming timeslot, transmitting the data of said incoming timeslot via said existing data transmission connection to a far-end network end node, and transmitting said request data subset to said far-end network end node for signalling said requested status to a remote client which is connected to said far-end network end node via a second user network interface.
