Abstract:
A byte engine for interfacing to an STS-N SONET/SDH data stream and an elastic storage means in response to provisioning information , comprising:a control means responsive to the provisioning information that describes the STS-N SONET/SDH data stream and a frame start signal for generating control signals to control the interfacing to the SONET/SDH data stream and the elastic storage means; a SONET/SDH receive byte engine, coupled to the control means, for storing information received from the SONET/SDH data stream into the elastic storage means and for processing information a byte at a time and storing N intermediate states as the processing changes from one of the N equivalent STS-1 frames to the next, in response to the control signals and the provisioning information that describes the STS-N SONET/SDH data stream; and a SONET/SDH transmit byte engine, coupled to the control means, for reading information from the elastic storage means and transmitting the information into the SONET/SDH data stream and for processing information a byte at a time and storing N intermediate states as the processing changes from one of the N equivalent STS-1 frames to the next, in response to the control signals and the provisioning information that describes the STS-N SONET/SDH data stream.
