Abstract
The invention provides a data unit for the rate adaptation to overspeed data in fully digital systems adapted to the transmission of block mode asynchronous data. The data unit comprises an interface circuit for receiving data from a transmission facility, a universal asynchronous receive transmit circuit (UART) for interfacing to data terminal equipment, a dynamically adjustable baud rate generator for driving the UART, and a microprocessor for controlling the transfer of data from the transmission facility to the output of the UART. Upon detection of overspeed data being received, the frequency of the baud rate generator is increased for the remainder of the byte being processed in the UART. The baud rate generator is reset to its nominal frequency at the boundary of each byte outputted from the data unit.
