ABSTRACT:
A system for controlling a change of sequence order of channel data for a telecommunication terminal device including: a plurality of channel boards provided to a terminal device and each having transmitting and receiving portions; a multiplexing portion for multiplexing data sent from the channel boards so as to generate transmission data; a demultiplexing portion for demultiplexing reception data so as to send it to the channel boards; and a sequence order address signal generator for generating a sequence order address signal to a memory. The system includes a memory for receiving the sequence order signal and capable of rewriting data for changing a sequence order of channel data; a memory wire control portion for controlling data write access for the memory; and a channel pulse conversion portion for receiving data read out from the memory and for generating a channel pulse corresponding to the data read out from the memory, in which a data communication sequence order between the channel boards and the multiplexing portion is determined by the channel pulse.
