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.
