Abstract :
CCITT Recommendation X.25 defines the interface between data terminal equipment (DTE) and data circuit-terminating equipment (DCE) operating in packet mode over a dedicated circuit. As such, X.25 views the interface from the perspective of the DCE and is written specifically for a DTE/DCE interface between host and network. ISO (International Organization for Standardization) standards 7776 and 8208 are the ISO versions of the X.25 link and packet levels, respectively, but have a wider scope than X.25 in also describing a DTE/DTE interface. Furthermore, ISO 8208 provides guidelines for connecting a private data network to a public data network using X.25 procedures. An overview of the technical difference between X.25 and the two ISO standards is presented
