  • Bus interface for transfer of multiple SONET/SDH rates over a serial backplane
    Patent number: 7593411
    Abstract: A bus interface for transfer of SONET/SDH data that supports a plurality of SONET/SDH flows. The invention supports two line coding schemes: 8B/10B encoding of STS-12, and SONET scrambled coding for STS-12, STS-48, and STS-51. The invention additionally supports two modes of line testing: entire links can be tested by inserting and checking PRBS sequences, and the SPE payload of the largest concatenated STS-Nc which the link can carry (STS-12c, STS-48c, STS-51c) can be individually tested by inserting and checking PRBS sequences.

  • System for efficient broadband data payload conversion
    Patent number: 6603776
    Abstract: The system for broadband data payload conversion functions to efficiently convert broadband data between two sets of data formats. In particular, this software system converts between AUG/AU3/VC3 clear channel payloads and AU4/VC4/TU3/VC3 clear channel payloads in an efficient manner, which also complies with the industry standard data formatting requirements. The present system implements an efficient data format conversion process that uses existing circuitry and can effect the data format conversion with only a few bytes of delay instead of an entire frame of delay as is typically found in existing systems. This is accomplished by manipulating the format conversion to simplify the format conversion process.
