<P>PROBLEM TO BE SOLVED: To assign an Ethernet to a logical interface on an interface device for an IP router. <P>SOLUTION: GbE/ODU adapters 14-0 to 14-31 map gigabit Ethernet(R) frames from logical interfaces 15-0 through 15-31 to payloads compliant with ODU0 standard. ODU adapters 13-0 to 13-31 map payloads from GbE/ODU adapters 14-0 through 14-31 to ODU0 signals. The ODU0 signals from the ODU adapters 13-0 to 13-31 are multiplexed by a multiplexer/demultiplexer 12, and OTU3 signals are output onto an optical fiber 11. OTU3 signals input from the optical fiber 11 are processed in the reverse order. It is also possible to include Ethernets with different speeds. <P>COPYRIGHT: (C)2012,JPO&INPIT |
