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