Connecting more computers

By attaching a DIVA LAN ISDN Modem to an Ethernet hub from other manufacturers, you can interconnect more than four computers (or other devices), enabling them to share the ISDN connection provided by the DIVA LAN ISDN Modem.

Connecting the DIVA LAN ISDN Modem to a third-party Ethernet hub.

In this example, all computers can share the ISDN link to exchange data, send e-mail, or surf the Web. There is no need for multiple modems, phone lines, or ISP accounts.

Note Two DIVA LAN ISDN Modems cannot be connected in this manner.

Total network security

The Network Address Translation (NAT) feature keeps local IP addresses hidden so that your computers are invisible to the outside world.

Password security, filtering, and the ability to disable support for incoming calls prevents intruders from breaking into the DIVA LAN ISDN Modem itself.

Compression for faster throughput

The DIVA LAN ISDN Modem provides data compression to achieve throughput rates of up to 512 kbps. That's four times the ISDN remote access speed of 128 kbps.
