          -- Based on the transmission media underlying each interface

          -- group is mandatory for that system.

          -- When Internet-standard definitions for managing
          -- transmission media are defined, the transmission group is
          -- used to provide a prefix for the names of those objects.

          -- Typically, such definitions reside in the experimental
          -- portion of the MIB until they are "proven", then as a
          -- part of the Internet standardization process, the
          -- definitions are accordingly elevated and a new object
          -- identifier, under the transmission group is defined. By
          -- convention, the name assigned is:
          --
          --     type OBJECT IDENTIFIER    ::= { transmission number }
          --
          -- where "type" is the symbolic value used for the media in
          -- the ifType column of the ifTable object, and "number" is
          -- the actual integer value corresponding to the symbol.

                      Note that it is strongly recommended that this
                      object be stored in non-volatile memory so that it
                      remains constant between re-initializations of the
                      network management system."
