    DESCRIPTION
        "A MIB module for extending the DSG-IF-MIB (ITU-T J.128
        10/2008) to add objects which provide additional
        management information about DOCSIS Set-top Gateway (DSG)
        not available in DSG-IF-MIB.

        The DSG provides a one-way IP datagram transport for Out-Of-Band
        (OOB) messaging to cable set-top clients. The one-way IP
        datagram transport is called a DSG Tunnel. A DSG Tunnel carrying
        either a broadcast, unicast or multicast IP datagram stream
        originating at the DOCSIS Set-top Gateway and carrying
        Out-Of-Band messages intended for set-top clients. It is carried
        over one or more downstream DOCSIS channels. Multiple DSG
        tunnels may exist on a single downstream DOCSIS channel."
