AEP
The Applied Innovation encapsulation protocol works with messages traveling
between X.25 and TCP/IP protocols. AEP allows for packet preservation of X.25 data
when transport is over a TCP/IP network. This protocol keeps packet boundaries
intact, which is useful for X.25 applications that are highly sensitive to packet integrity.
AEPN
The Applied Innovation encapsulation protocol with the network option is used for
messages traveling between X.25 and TCP/IP protocols. In addition to the services
provided by the AEP protocol, the AEPN also passes X.25 Q-bit information over a
TCP/IP connection. AEPN also handles special information such as break signals.
