Abstract
The present invention provides telecommunications transport methods and systems for the transparent mapping/demapping of client data signals without the insertion/deletion of idle characters for client data signal rate adaptation. These methods and systems include mapping an incoming client data signal to and demapping an outgoing client data signal from a transport frame comprising: a first segment that is dedicated to client data; a second segment that is dedicated to fixed stuff, wherein the fixed stuff comprises, for example, network management information; a third segment that is dedicated to justification data for supporting a client data signal rate adaptation function; and a fourth segment that is dedicated to justification control information for indicating whether the third segment is used for client data or fixed stuff, wherein the justification control information is redundant for error protection purposes.
