Abstract
A communication terminal apparatus for multiplexing a plurality of different types of data and for performing communications using the multiplexed data includes a network control unit connected to a communication network for transmission and reception of the plurality of different types of data. A multiplexing unit generates transmission data by multiplexing the plurality of different types of data and outputs the transmission data to the line control unit. A synchronizing unit generates a transmission synchronizing signal of the multiplexing unit. A separating unit separates reception data received from the network control unit in units of data type synchronously with the transmission synchronizing signal generated by the synchronization unit. A loop back path can be used for looping back and inputting the separated reception data to the multiplexing unit, and an adding unit adds dummy data to the looped back reception data.
