Communications Server Services
The multiport router acts as a communications server to connect terminals, printers,
modems, microcomputers, and remote LANs over asynchronous serial lines to an
internetwork. The communications server uses a set of connection services to allow remote
networks access to an internetwork of LANs and WANs.
The router supports four types of server operation:
• Remote node services
• Terminal services
• Asynchronous routing services
• Protocol translation services
Remote Node Services
Remote node services support remote network connectivity with Serial Line Internet
Protocol (SLIP), Point-to-Point Protocol (PPP), or AppleTalk Remote Access Protocol
(ARA protocol).
Single users with laptop or desktop computing devices can access corporate data and many
other resources on the Internet using dialup lines. Figure 1-5 shows an example network.
