DProtocols Overview D

This appendix provides a short overview of the following protocols used by the iSPAN-Serial WAN adapter:

•X.25

•Frame Relay

•Point-to-point

For detailed information, refer to relevant network protocol documentation.

X.25 Protocol

X.25 packet switched networks allow remote devices to communicate across high-speed digital links without the expense of individual leased lines. Packet switching is a technique whereby the network routes individual packets of HDLC data between different destinations based on addressing within each packet. The X.25 protocol encompasses the first three layers of the OSI 7-layered architecture defined by the International Standards Organization (ISO).

Layer 1: Physical Layer

The Physical Layer is concerned with electrical or signaling. It includes several standards such as V35, RS232, and X.21.
