How it works: You connect the DIVA LAN ISDN Modem to an ISDN line (which is part of the telephone network). You also contact the corporate network and obtain its ISDN phone number and associated user names and passwords. Once the DIVA LAN ISDN Modem is configured with this information, it automatically calls the remote site to send data to it, for example, when a local users sends e-mail, or shares folders with Windows Network Neighborhood.

Note You cannot connect to a corporate network if it is also using a DIVA LAN ISDN Modem.

Creating a VPN

Connect branch offices and telecommuters into an enterprise-wide Virtual Private Network (VPN) over the Internet. This eliminates the long-distance charges, network management problems, and security responsibilities associated with traditional WANs.

Attaching telephones and fax machines

The DIVA LAN ISDN Modem is available in a version that features two analog ports for the connection of telephones, fax machines, and analog modems. The DIVA LAN ISDN Modem takes advantage of the flexibility of ISDN to enable you to make or receive phone calls or faxes, while at the same time connecting to the Internet or a corporate network with your computers. This can eliminate the need to install additional analog phone lines.
