A circuit-switched WAN uses the phone company as the service provider, either with analog dial-up or digital ISDN connections. With circuit-switching, if you need to connect to the remote LAN, a call is dialed and a circuit is established; the data is sent across the circuit, and the circuit is taken down when it is no longer needed. Circuit-switched WANs usually use PPP, HDLC, or SLIP, and they tend to be really slow—anywhere from 19.2K for analog dialup to 128K for ISDN using a Basic Rate Interface (BRI). They can also get expensive because most contracts specify a pay-per-usage billing.
