Networking protocols annotated with ASN. 1 of ITU-T X. 680 is readable, however its implementation with traditional routine
call is complex and difficult. Object Oriented idea is introduced to get the following simplicities: Make the implementation
of protocol data unit annotated with ASN. 1 similar to its definition with little or even without any changes. The framework
for encapsulation of ASN. 1 data types into objects discussed here is not only suitable for PER X. 691 but also suitable for
BER X. 690.
Key words object oriented implementation - template class - C++ - ASN. 1 - ITU-T X. 680 - ITU-T X. 691 - ITU-T X. 690 - PER - BER
