Making and Receiving Data Calls

Your phone is capable of making and receiving secure and clear data calls. Secure data

calls involve making a data call to another secure phone, and can be used to send files

(via FTP) and telnet. There are two types of clear data calls: clear async data calls and

clear packet data calls.

Clear async data calls involve making a data call to another phone via a

communications application on your computer or handheld device, and can be used

to send faxes, files (via FTP), and telnet.

Clear packet data calls involve using a dial-up connection to access an internet

server (IP address), and can be used to send/receive e-mail and browse the

Internet.

In effect, your phone can serve as a clear or secure modem to transfer information to/from

a computer or handheld device. Your phone can be connected to a computer or handheld

device using a separately-provided data cable (for details on ordering a data cable, see

“Accessories” on page 131). Before making a data call, you must set up the computer or

handheld device to work with your phone. See the documentation that comes with your

data cable for information on connecting and setting up a computer or handheld device.

Making Secure Data Calls

Unlike clear data calls, which are controlled directly from your computer, you must initiate

and end secure data calls using your phone’s keys. To make a secure data call, you first

need to set the desired data rate for the call. Then, you specify that the next call will be a

secure data call and initiate the call.

Note

If the ‘Secure Data’ Access Control setting on your phone is disabled, you will

not be able to make a secure data call (see “Viewing Access Control Settings”

on page 22).

While making a secure data call, you can still access the Security menu.
