GPRS Advanced tabs

	Authentication is used by some network operators to
	identify the mobile phone connecting to their GPRS
	network. There are different methods, or protocols,
	for doing this.
	Normal: PAP (Password Authentication Protocol).
	The user's username and password are transmitted
	over the network in an unencrypted form.
	Secure: CHAP (Challenge Handshake
	Authentication Protocol). The user's username and
	password are never transmitted over the network.
	None: No authentication is required by the network
	operator.
QoS	Check with your network operator before changing
	any of the QoS (Quality of Service) settings.
	The settings Precedence, Delay, Peak rate, and Mean
	rate are all by default set to Subscribed, which means
	that your operators default QoS (Quality of Service)
	values will apply. Reliability is set as Class 3 by
	default.

New Dial-Up or High-Speed Dial-Up account

Your Internet Service Provider (ISP) supplies you with your User name, your Password, and their Phone number, which your P910a dials to connect to the Internet. If you have a High-Speed DialUp account with your network operator you can increase the speed of your connection by making settings on the Speed tab

under Advanced.

Tip To avoid having to change the phone number when you travel abroad: enter the international dialing prefix (for example '+') and the appropriate country code for your ISP.

For some accounts you may also need to make advanced settings.

Select Advanced and enter settings on the tabs as described below

Dial-Up and High-Speed Dial-Up Advanced tabs

Log in The settings on this tab deal with IP and DNS addresses. For an explanation of these settings, see Log in in the ‘GPRS Advanced tabs’ on page 157.

Script As an alternative to entering your username and password to access the Internet you may need to use a login script stored on your P910a. Although uncommon, scripts may be required by your Internet Service Provider (ISP).

Select the Use login script check box and enter the script text in the Script editor.

If you select the check box Plain text authentication (required by some ISPs), the security of your connection will decrease during the connection process. Once you are connected, the security of your connection will be restored.
