    In general, the role/purpose of the TOH bytes is to fulfill the following functions.
    To support STS-1 Frame Synchronization
    To support Error Detection within the STS-1 frame
    To support the transmission of various alarm conditions such as RDI-L (Line - Remote Defect Indicator) and
    REI-L (Line - Remote Error Indicator)
    To support the Transmission and Reception of "Section Trace" Messages
    To support the Transmission and Reception of OAM&P Messages via the DCC Bytes (Data Communication
    Channel bytes - D1 through D12 byte)
    The roles of most of the TOH bytes is beyond the scope of this Data Sheet and will not be discussed any
    further. However, there are a three TOH bytes that are important from the stand-point of this data sheet, and
    will discussed in considerable detail throughout this document. These are the H1 and H2 (e.g., the SPE
    Pointer) bytes and the H3 (e.g., the Pointer Action) byte.
    Figure 42 presents an illustration of the Byte-Format of the TOH within an STS-1 Frame, with the H1, H2 and
    H3 bytes highlighted.
