Connecting to a Corporate Network

Intranets are an effective way for organizations to share data and resources. The DIVA LAN ISDN Modem makes it easy for branch offices and telecommuters to connect to a corporate Intranet.

This chapter explains how to configure the DIVA LAN ISDN Modem to connect with a remote network only. If you need to connect to the Internet and a remote network at the same time, see “Concurrent Internet and Intranet connections” on page 119.
