Abstract
In a transmission apparatus in a ring network, provided are a demultiplexing section for demultiplexing multiplexed transmission signals and outputting thus demultiplexed signals; a branching and inserting section adapted to cause, of the demultiplexed transmission signals, a transmission signal of a desired channel to branch out into another line and insert a signal from another line as a transmission signal into the channel from which the transmission signal branches out; and a multiplexing and transmitting section for multiplexing the transmission signals from the branching and inserting section and transmitting thus multiplexed signal as a multiplexed transmission signal to a line which becomes a relaying destination of transmission; wherein the branching and inserting section comprises a transmission route setting mechanism for setting a transmission route of each set of transmission signals such that each set of the transmission signals are transmitted by one of a plurality of kinds of transmission systems, thereby constructing a ring network having a plurality of transmission systems different from each other.
