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.
