• Install one or more modems on the calling and receiving servers.
• Configure the communication port.
• Create a dialup modem connection from the calling server to the receiving server. Domino uses either an IBM® Lotus® Notes® Direct Dialup connection or a Network Dialup Connection to communicate with another server over a modem. The type of connection required depends on whether each server is directly connected to a modem.

  For information about creating dialup connections, see the topics "Creating a Notes Direct Dialup connection" and "Creating a Network Dialup connection" later in this chapter.

The number of modems that you can use on a server is dependent on the operating system and system resources -- for example, the number of available communication ports. Each modem needs its own communication port.

If you expect heavy dialup use, install additional modems or install a multiple-port communication board to connect multiple modems to multiple communication ports on a single board.

Use these questions to help you determine the number of modems:

1. How many users and servers do you want to be able to use the server simultaneously?

The number of modems that you install on a remote server determines the number of users and servers that can access it simultaneously. Consider the expense of purchasing more modems against server accessibility.

To reduce server demand, encourage users to keep local replicas of databases on their workstations, work on them without a dialup modem connection, then connect to the central server to exchange new and updated documents with the central server's database.

If the server supports a high number of users who connect exclusively over dialup connections -- for example, when a server's primary users are field personnel who are always on the road -- dialup demand for the server is higher than on a server where users only occasionally use modem connections.
