ABSTRACT:
A system (10) for transmitting data is presented. The system (10) includes a data transmission medium (12, 28) and an overhead generator (40) connected to the data transmission medium (12, 28), such as through a switch. The overhead generator (40) digitally encodes control data into one or more bytes in a data transmission frame (70) used to transmit data over the system (10). The system also includes a monitor/selector (22) coupled to the data transmission medium (12, 28). The monitor/selector (22) reads the digitally encoded control data in the byte in the data transmission frame (70). A processor (24) coupled to the monitor/selector (22) processes the digitally encoded control data in the data transmission frame (70).
