NTPRowStatus ::= TEXTUAL-CONVENTION
    STATUS      current
    DESCRIPTION
        "The NTPRowStatus textual convention is modeled after the
         RowStatus textual convention of RFC 1903, but is simpler
         because it only allows one create operation (the create-
         and-go of RowStatus) and does not allow row deletion. If
         the state of the status column is `notInService' and the
         management station tries to set it to `create', the
         corresponding row is created and the operation is successful.
         If the set to `create' is attempted when the status column
         is in state `active', the operation fails and inconsistentValue
         is returned. A management station is not permitted to delete
         the conceptual row; deletion is carried out by the agent
         in an autonomous manner."

		   -- the following values are states:
		   -- these values may be read, but not written
		   active(1),
		   notInService(2),
