Abstract:
1. A multiplexed signal transmitter comprising: input interfaces of which an arbitrary one is provided for a respective channel of Gigabit Ethernet to receive a data from the channel of Gigabit Ethernet; transmission memories for storing data sent from the input interfaces; a transmission selector for alternately reading stored data in the transmission memories at a speed; and a transmission interface for outputting data alternately read by the transmission selector to a transmission line, wherein input transmission signals from a plurality of channels of Gigabit Ethernet are multiplexed to be sent to the transmission line, wherein data selectors are provided between the input interfaces and the transmission memories, and connected to a 10-bit data generator for sending to the data selectors particular 10-bit data of which an arbitrary one is predetermined for the respective channel of Gigabit Ethernet, the input interfaces send data in a 10-bit data format via the data selectors to the transmission memories, and the data selectors are adapted, before the input interfaces receive data from the channels of Gigabit Ethernet, to have changed paths for receiving the particular 10-bit data sent from the 10-bit data generator so that they can be sent to the transmission memories, and after the input interfaces have received data from the channels of Gigabit Ethernet, to have changed paths so that data sent from the input interfaces can be sent to the transmission memories.
