From the user’s perspective, using remote access usually means sitting at home or in a hotel room, “dialing in” (using one of several technologies) to their employer’s or ISP’s remote access server.

After they connect, the server authenticates them by validating their user ID, password, and possibly other special criteria like caller ID, time of day, etc. Once authenticated, they have access to the corporation’s, or the entire Internet’s, resources, similar to other workstation on the corporation’s or ISP’s LAN.

The remote server that users dial into can be a dedicated hardware box such as those from Intel/Shiva or a general purpose server (running Windows, Linux, or another NOS) outfitted with cards for the appropriate incoming line type (regular telephone line, ISDN, etc.) which has been set up to accept and validate incoming dial-in users. Sometimes routers themselves contain dial-in ports that users dial into directly.
