Abstract
A device for an isochronous data communication system between a first data terminal having a first clock and a remote communication unit having a second clock. A clock multiplex circuit receives the first and second clock signals. A logic means selects either the first or second clock signal as a data timing signal. The data timing signal will correspond with the second clock signal if present, if no second clock signal is present then the data timing signal will correspond with the first clock signal. A communication control device receives the data timing signal for controlling the timing of the communication.
