Please send vendor-specific requests to the vendor in question - in this case [EMAIL PROTECTED] As far as finding other solutions, both freeware and commercial products, see http://asn1.elibel.tm.fr/en/links/index.htm#tools. Not to suggest that you will find a finer solution than the OSS ASN.1 Tools :-). ------------------------------------------------------------------------- Bancroft Scott Toll Free :1-888-OSS-ASN1 OSS Nokalva International:1-732-302-0750 [EMAIL PROTECTED] Tech Support :1-732-302-9669 x-1 1-732-302-9669 x-200 Fax :1-732-302-0023 http://www.oss.com > > On Wednesday 31 October 2001 02:56 pm, you wrote: > > MEDIA-GATEWAY-CONTROL DEFINITIONS AUTOMATIC TAGS::= BEGIN > > > > MegacoMessage ::= SEQUENCE > > { > > authHeader AuthenticationHeader OPTIONAL, > > mess Message > > } > > AuthenticationHeader ::= SEQUENCE > > { > > secParmIndex SecurityParmIndex, > > seqNum SequenceNum, > > ad AuthData > > } > > > > SecurityParmIndex ::= OCTET STRING(SIZE(4)) > > > > SequenceNum ::= OCTET STRING(SIZE(4)) > > > > AuthData ::= OCTET STRING (SIZE (12..32)) > > > > Message ::= SEQUENCE > > { version INTEGER(0..99), > > -- The version of the protocol defined here is equal to 1. > > mId MId, -- Name/address of message originator > > messageBody CHOICE > > { > > messageError ErrorDescriptor, > > transactions SEQUENCE OF Transaction > > }, > > ... > > } > > > > END > > > > The above ASN.1 partial structure is specified for MEGACO. > > We are implementing encoding and decoding in BER without the help of any > > tool or compiler. > > We are stuck with the Tagging issues . > > Kindly specify the solution and how the tagging is to be carried out for > > the above substructure without the help of any tool or compiler. > > > > Kindly treat this as urgent and reply at the earliest. > > > > Best Regds, > > parag > > > > -------------------------------------------------------------- > > Dexcel Electronics Designs (P) Ltd., Bangalore, India > > ------------------------------------------------------- > > -------------------------------------------------------------- > Dexcel Electronics Designs (P) Ltd., Bangalore, India > > >
