<p>A line interface incorporated in a hgh-speed transmission line system for transmitting and receiving one time slot of the transmission line. A speed changing circuit replaces a high-speed transmission line with n low-speed internal lines. Hence, data transmitting and receiving circuits in each internal unit operate at low speed, saving power to be consumed by the internal unit. Since the time slots which each internal unit uses are the same on all of the internal lines, a single time slot selecting circuit suffices for each internal unit, promoting efficient circuit configuration. <IMAGE></p> |
