Abstract:
1. A method of determining a transmission parameter for a channel at a multi-channel interface, the channels serving either for communicating between nodes of a transmission system according to one of a first set of transmission parameters or for communicating with a subscriber according to one of a second set of transmission parameters, comprising the steps of: decoding a received data stream at the multi-channel interface between the nodes of the transmission system by applying each transmission parameter of a selected one of the first and second sets of transmission parameters in turn until meaningful data result or all of the transmission parameters of the selected set have been applied; first deciding from the results of the decoding step whether the channel is for communicating between nodes or for communicating with a subscriber; wherein if the channel is determined to serve for communication between the nodes of the transmission system, then decoding a first data quantity of the data stream under the assumption that it is from a communication channel of a first type; and
