Well, if you read one of those 2 ASN.1 books, you'd know. Or, you could read-up the ITU-T X.680 specification (upto 3 ITU-T standards/year are free for download at the ITU-T website).
OPERATION, ERRORS, ARGUMENT are ASN.1 macros. In any case, this is GSM MAP, not TCAP! -----Original Message----- From: Dharshana Eswaran [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 08, 2006 12:22 PM To: Dutta, Banibrata (STSD); [email protected] Subject: Sample ASN.1 code I just wanted to know, Wat should i conclude or understand from this sample code??? -- operation types definition ProcessUnstructuredSS-Data::= OPERATION -- Timer T(PUSSD)= 15s to 30s ARGUMENT ss-UserData SS-UserData RESULT ss-UserData SS-UserData -- optional ERRORS{ SystemFailure, UnexpectedDataValue} NotifySS ::= OPERATION ARGUMENT notifySS-Arg NotifySS-Arg ForwardChargeAdvice ::= OPERATION -- Timer T(AoC)= 1s to 40s ARGUMENT forwardChargeAdviceArg ForwardChargeAdviceArg RESULT ForwardCUG-Info ::= OPERATION ARGUMENT forwardCUG-InfoArg ForwardCUG-InfoArg BEST REGARDS.....
