  • Patent number: 7315511
    Abstract: Disclosed herein is a SONET/SDH transmitter provided in a transmission system in which a SONET/SDH network and an IP network are connected with optical LAN-IF. The SONET/SDH transmitter has a redundancy transmission line structure consisting of two transmission lines, a K-packet processing section, and a transmitting section. The K-packet processing section is used for generating a specific byte (SONET K1/K2 byte) of data representing transmission-line switching control information about the transmission lines, packetizing the generated data, and outputting a packet. The transmitting section is used for transmitting the packet to the transmitter provided opposite through the transmission lines. This SONET/SDH transmitter further has a redundancy line switching section.
