      "An extension to the Cisco ATM MIB module for managing
    ATM implementations.
    
    Acronyms and terms used in the MIB module:
    
    AAL5        -- ATM adaptation layer 5.
    AIS         -- Alarm Indication Signal.
    CC          -- Continuity Check.
    End-to-end  -- End-to-end continuity checking.
                   Monitoring occurs on the entire VC
                   between two ATM end stations.
    F5 OAM      -- OAM information flow between 
                   network elements (NEs) used within 
                   virtual connections to report degraded 
                   virtual channel performance.
    OAM         -- Operations, Administration 
                   and Maintenance.
    RDI         -- Remote Detection Indication.
    Segment     -- Segment continuity checking. 
                   Monitoring occurs on a VC segment
                   between a router and a first-hop 
                   ATM switch.
    VC          -- Virtual Channel.
    VCC         -- Virtual Channel Connection.
    VCL         -- Virtual Channel Link.";
