12: Data Connections

•Dial-Up Connections

•Quick 2 Net Connections

•Express Network Connections

Note: You cannot have a data and a voice connection at the same time. If you have a data connection when an incoming call occurs, your caller will get a busy signal or be put through to your voice mail box.

Note: Depending on your billing plan, there may be a surcharge for 1xRTT calls.

The Data tab on the main Watcher window is used to make data connections for any of these purposes:

•Browsing the Internet

•Sending and receiving e-mail

•Dialing into your corporate network

•Sending and receiving faxes

The AirCard 555 network card offers three types of data connections:

•Dial-up connection – in this type of connection, you provide the phone number and the AirCard dials the number. Using this type of connection, you can connect to any other modem and receive faxes. The maximum speed of this type of connection is 14.4 kbps.

•Quick 2 Net connection – in this type of connection, the AirCard makes a direct Internet connection. The data transmission speed for this type of Internet connection is the same as for a dial-up connection but the time required to initiate the connection is shorter. Quick 2 Net avail- ability is dependent on your service provider. (This type of connection is sometimes called Quick Net Connect or QNC.)

•Express Network (1xRTT) connection – in this type of connection, the AirCard establishes a high-speed Internet connection to the CDMA network. (You do not need to provide a phone number and there is no dialing involved.) The maximum speed of this connection is 144 kbps but it is only available in areas where 1xRTT has been imple- mented.

The Express Network connection provides access to the Internet. Once the connection is established, you can open your browser and connect to any web site that is accessible through the Internet, or access other Internet services (such as e-mail).
