Using X.25
An X.25 network transmits data with a packet-switching protocol, bypassing noisy telephone lines. This protocol relies on an elaborate worldwide network of packet-forwarding nodes that can participate in delivering an X.25 packet to its designated address.
Network Connections supports X.25 by using packet assemblers/disassemblers (PADs) and X.25 cards. You can also use a modem and special dial-up X.25 carriers in place of a PAD or X.25 smart card on your computer.
Remote access clients running Windows XP or a member of the Windows Server 2003 family can either use an X.25 card or dial in to an X.25 PAD to create connections. To accept incoming connections on a computer using X.25 running Windows XP or a member of the Windows Server 2003 family, you must use an X.25 card.
