      "The Synchronous Ethernet (SyncE) MIB is defined
    for monitoring network synchronization based on
    ITU-T G.781 clock selection.
    
    Synchronous Ethernet (SyncE) is a standard defined
    for delivering timing to the remote NEs through a 
    Packet Network.   SyncE is well defined by ITU-T
    which included G.8261, G.8262, G.8264 and G.781.
    It leverages the PHY layer of Ethernet to transmit
    frequency to the remote sites.  Its functionality
    and accuracy mimics that of the SONET/SDH network
    because of its physical layer characteristic.
    In order to allow best clock source traceabiliy,
    correctly define the timing source and helps
    preventing timing loop, Synchronization Status
    Message is required for SyncE.  This is similar
    to SONET/SDH.  However, since SONET/SDH use 4 bits
    from the two S bytes in the SONET/SDH overhead
    frame for such message, Ethernet relies on a
    different channel called ESMC (Ethernet
    Synchronization Messaging Channel) which is based
    on IEEE 802.3 Organization Specific Slow Protocol.
