Terminal Server is an equipment that allows serial line devices to connect to a network. Simple terminal servers only allow dumb terminals (perhaps via modems and telephone lines) something like telnet access. Sophisticated terminal servers allow (semi-)intelligent terminals (e.g. PCs) to connect to the network using higher-level protocols (e.g. PPP). If connections are only via modems, then this equipment may also be referred to as a modem server.
