Migrating X.25 over PSI to X.25 over TCP/IP (XOT)

Application Migration
After the XOT interface is configured, the X.25 application uses the XOT interface to communicate
with the peer X.25 systems (an XOT or an XOL or a PSI port.) The migration of X.25 from PSI to
XOT is seamless.
The X.25 applications require minimal or no changes after migration to XOT. The recommended
packet size for XOT is 1024 bytes in Layer 3.
XOT interfaces should always have interface names in the format xot<number>. The application
would have to change the interface name accordingly. However, it must be modified and
re-compiled if the interface name is hardcoded as a part of the application.
X.25 applications are binary compatible if the applications require no change in the packet size
or the interface name while migrating to XOT.
