Dear Sir,
Thanks for your suggesstion on using a tool to encode and decode the ASN.1
type of data using BER.
Sir, We searched the entire web for a freeware satisfying encoding rules
specified in X.690 (1994) but were able to find only an evaluation copy of
OSS ASN1C compiler satisfying our requirements. One more thing is our
specification(i.e) Megaco Structures are defined using the notation
X.680(1997) . But the trial expires after 30 days.
So SIr , Pls Can you specify some other freeware satisfying our above
mentioned requirements.
Kindly treat this as urgent,
Best Regards
Parag
