Latest Patents

Yamamura holds a patent for a "Data link layer processor system for a local exchange system." This system comprises a plurality of in-service data link layer processors (DLLPs) and spare DLLPs. The innovative design allows for seamless switching between the in-service DLLP and the spare DLLP. This is achieved by coupling both DLLPs with the transmission line and transferring logical links from the in-service DLLP to the spare DLLP one by one. The process includes frame multiplexing the data from the spare DLLP with the data from the in-service DLLP. Once all logical links are transferred, a switch decouples the in-service DLLP, leaving the spare DLLP coupled with the transmission line for normal operation.
