Abstract:
A synchronous data transmission method for transmitting control or synchronization information, the control or synchronization information including terminal interface user data and status information, through a traffic channel or a set of traffic channels in a telecommunication system supporting point-to-point transmission, said method comprising:inserting, at a transmitting end, the control or synchronization information to an address field of protocol data units of the transmission protocol used at the terminal interface and supporting point-to-multipoint transmission; transmitting the protocol data units containing the control or synchronization information through said traffic channel or set of traffic channels, a maximum data rate of the traffic channel or a total maximum data rate of the set of traffic channels being equal to a user data rate at the terminal interface; and extracting, at a receiving end, the control or synchronization information from the address field of protocol data units and restoring an original redundancy to the protocol data units.
