The object:

    frDlcmiState OBJECT-TYPE
        SYNTAX INTEGER      {
            noLmiConfigured (1),
            lmiRev1         (2),
            ansiT1_617_D    (3),  -- ANSI T1.617 Annex D
            ansiT1_617_B    (4),  -- ANSI T1.617 Annex B
            ccitt_933_A     (5)   -- CCITT Q933 Annex A
        }
        MAX-ACCESS   read-write
        STATUS   current
        DESCRIPTION
           "This variable states which Data  Link  Connec-
           tion Management scheme is active (and by impli-
           cation, what DLCI it uses) on the  Frame  Relay
           interface."
       REFERENCE
          "Draft American National Standard T1.617-1991"
      ::= { frDlcmiEntry 2 }

Is missing one value, in my reckoning.  ANSI T1.617a-1994 revises
Annex D in an incompatible way.  (Thanks, ANSI!  The "element
identifier" of "Link integrity verification information element" is
changed from 0x19 to 0x03.)

I'd say it should be revised to:

    frDlcmiState OBJECT-TYPE
        SYNTAX INTEGER      {
            noLmiConfigured   (1),
            lmiRev1           (2),  -- Interim LMI Revision 1

            ansiT1_617_B      (4),  -- ANSI T1.617-1991 Annex B
            ccitt_933_A       (5),  -- CCITT Q933 Annex A
            ansiT1_617_1994_D (6)   -- ANSI T1.617a-1994 Annex D
        }
        MAX-ACCESS   read-write
        STATUS   current

(Note also that many of the ANSI standard references are outdated.)
