New Dialup or High-Speed Dialup account
Your Internet Service Provider (ISP) supplies you with your
Username , your Password , and their Phone number , which your
P900 dials to connect to the Internet. If you have a High-Speed
Log in
The settings on this tab deal with IP and DNS
addresses.
The DNS address uniquely identifies your Internet
Service Provider (ISP)'s computers, which your P900
uses to connect to the Internet. Your P900 can
normally retrieve these addresses automatically from
most ISPs.
If, after setting up an Internet account, you cannot
connect to the Internet and you suspect these
addresses are incorrect, ask your ISP for their
primary and secondary DNS addresses.
An IP address consists of four 3-digit boxes, and the
valid input is between 000 and 256 in each box.
Proxy
A proxy server is a computer connected between
your P900 and the computer you communicate with.
This arrangement can be used for connections to
Remote Sync servers, or within a company network.
If this setting is needed, your company's Information
Services department or Remote Sync provider must
give you instructions.
Other
If your ISP supports Point-to-Point Protocol (PPP)
extensions, you can select the
Enable PPP extensions
checkbox. PPP extensions allow your P900 to
provide features such as encryption, which increases
the security of your Internet connection.
GPRS Advanced tabs
Authentication is used by some network operators to
identify the cellphone 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 format.
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.
If your operator supports the use of
Header
compression , selecting On can speed up your
connection.
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.
