Configure X.25 over TCP (XOT)

Introduction to XOT Protocol

XOT (X.25 Over TCP) is a protocol that is supported by TCP, and implements the connection of two X.25 networks through IP network. The practical application environment is shown in the following figure.

Since the application of IP network is broader and broader, the practical applications of supporting X.25 data through IP net and connecting X.25 networks are becoming more and more. The conventional X.25 protocol is the third layer of the OSI seven-layer model, i.e., the network layer, for which the LAPB
