Abstract
SDH/SONET signals are transported as a service including payload and overhead information by mapping associated payload data or information and selected associated overhead data or information of at least one SDH/SONET client signal to be transported into a SDH/SONET server signal. More specifically, client overhead information of the SDH/SONET client signal is mapped into free overhead positions of the SDH/SONET server signal. The SDH/SONET server signal is then transported with the SDH/SONET client signal including associated payload and overhead information embedded therein.
Claims9
A method for transporting SDH/SONET client signals as a service, wherein an associate SDH/SONET client payload is embedded within a SDH/SONET server signal, comprising:
- mapping overhead information of at least one SDH/SONET client signal into the SDH/SONET server signal, wherein the client overhead information of the at least one SDH/SONET client signal is mapped into free overhead positions of the SDH/SONET server signal;
- and
- transporting the SDH/SONET server signal with the payload information and the mapped client overhead information of the at least one SDH/SONET client signal embedded therein.
A network element comprising:
- means for cross connecting overhead information of at least one SDH/SONET client signal within a SDH/SONET server signal;
- a client port for receiving and outputting SDH/SONET client signals that are transported as a service;
- a server port for a SDH/SONET server signal having at least one embedded client signal;
- and
- means for performing cross connections for entities respectively of the same logical layer.
