Abstract
An inter-repeater backplane that may operate in either a synchronous or asynchronous mode for data transmission. The inter-repeater backplane includes a bus of electrical signal conductors coupled between repeaters for communicating electrical signals and data transmission mode detector for determining whether to transmit data synchronously or asynchronously. Data is recovered from a received data packet and is reframed for transmission across the inter-repeater backplane. According to which mode of data transmission is selected, the data is then retimed and transmitted across the backplane. In the synchronous mode of data transmission, the data is synchronized with the system clock. When the asynchronous mode of data transmission is selected, the data is transmitted asynchronously with respect to the system clock. In the asynchronous mode, the recovered data is timed with a clock signal associated with the transmitting repeater.
