Abstract: A system communicating over a full duplex control channel of a multimedia communication link by using synchronization signals that may also function as a logical link command. Synchronization indicators are exchanged between two communicating devices for maintaining synchronization of a logical link. At least two different types of synchronization signals may be sent between the two devices as synchronization indicators. A first synchronization signal is used by default to maintain synchronization of a logical link. A second synchronization signal is used in place of the first synchronization signal to maintain synchronization of the logical link. The second synchronization signal may be used to imply a virtual link command to indicate that a device is ready to receive data or has successfully received data over the virtual link.
