asn格式文件的编译器

-- Abstract Syntax Notion (ASN.1) file for H.225.0 Version 4
--
-- File provided by Packetizer, Inc. - http://www.packetizer.com
-- Last Updated: 2 June 2001
--
-- History of changes:
--    17 Nov 2000
--	  Initial H.225.0v4 ASN.1 file
--    27 Nov 2000
--        Changed to "group" element of "CallsAvailable" from an
--	  OCTET STRING to an IA5String.
--    29 Nov 2000
--        Added the keyword OPTIONAL at the end of the "group" element
--        that was changed on the 27th (the OPTIONAL keyword was there
--	  previously)
--    04 Dec 2000
--        Added a comment to indicate the proper protocol identifier for
--	  H.225.0v4 messages
--    08 Dec 2000
--	  Added "neededFeatureNotSupported" rejection reasons to
--	  GRJ, RRJ, ARJ, LRJ, and SCR.  Also clarified the usage of the
--	  "empty" h323-message-body choice.
--    18 Jan 2001
--        Corrected the data type used for the field "tmsi" within the
--        structure "GSM-UIM".  Also corrected the size constraint for the
--        "imei" field within the same structure.
--    24 Mar 2001
--        Removed dependencies on H.248 from the ASN.1 syntax in H.225.0
--    02 Jun 2001
--        Added an "invalidCID" ReleaseCompleteReason code
--        Changed the definition of the CircuitIdentifier
--        Added hopCountExceeded and incompleteAddress LRJ reasons
