Chapter 3 – Using Your Wireless Modem
Multi-Tech Systems, Inc. MultiModem CDMA Wireless Modem User Guide 21
Internet access can be setup in Windows Dial-Up Networking (DUN) of the computer that the wireless modem is
serving. Setup procedures will vary according to the type of wireless service provider used. To access Dial-Up
Networking on your PC, go to Start > Settings > Network Connections.
• For point to point data, a circuit-switched data connection is used. The user can set up DUN to make a
conventional V.32bis modem connection to any terminating modem at the other end. The phone number
specified in DUN can be one supplied by the wireless service provider or another phone number related to
a different dialup modem service (e.g., a dialup modem service phone number from any commercial or
private dialup network).
• For CDMA 1x data, a single DUN number is generally used by all of a wireless provider’s subscribers
throughout its area of coverage; e.g., regional, nationwide, continental, etc. Rather than being a literal
phone directory number, as in conventional DUN, this is a code that gives the modem Internet access.
Normally, this phone number is #777.
Connecting to the CDMA Network for Internet Access
You will establish an Internet connection through a Windows dial-up session.
