Abstract
A device includes a processor and a time slot assigner, connected to a communication line via a physical layer unit. The physical layer unit is adapted to generate a communication line clock signal and a multi-frame synchronization signal. The device also includes a transmit media access controller (MAC) adapted to receive the multi-frame synchronization signal and the communication line clock signal and in response to scan, during a single multi-frame transmission period, multiple transmit MAC memory entry groups such as to retrieve transmission instructions and in response to enable access to the communication line. During a single multi-frame transmission period the transmit MAC accesses at least twice at least one transmit MAC memory entry group. The processor receives a processor clock signal that differs from the communication line clock signal. The MAC also performs reception operations using receive clock and sync signals.
