ABSTRACT:
The invention provides a time division multiplexing system for a digital exchange which suppresses appearance of a time slot which, although exchanging can be performed by a time division switch, is put into a non-used state to improve the efficiency in use and which allows line interface apparatus to be accommodated in a time division multiplexing highway even where the line interface apparatus require a multiplicity larger than that of the highway to suppress an increase in circuit scale and simplify the circuit construction. The system includes a multiplicity display section provided in each line interface section for setting and displaying a multiplicity of channels per one frame to be time division multiplexed and outputted by and from a line interface section, a multiplicity changing section provided in a multiplex conversion circuit corresponding to each time division multiplexing highway accommodated in the multiplex conversion circuit for changing the multiplicity of the time division multiplexing highway, and a control section for reading the multiplicity display sections and transmitting the multiplicities set in them to the corresponding multiplexing changing sections.
