Troubleshooting dial-up connections
The Nokia A032 uses PPP to connect and send
data to an ISP. A basic understanding of its
operation may be helpful if you're having
problems with a dial-up connection.
There are four phases to the connection
process:
1 Dialling the ISP phone number.
This phase checks the compatibility of the
modem on the other end of the phone line
and negotiates the speed of the connection
based on the quality of the phone line.
2 Talking to the ISP server and agree that it
can use the PPP protocol.
3 Identifying the user to the ISP by sending a
username and password.
4 Agreeing the IP addresses that will be used
during the session.
If all four steps complete the Nokia A032 will
be able to deliver and receive IP packets to and
from the Internet.
We'll look at each phase in detail and highlight
possible problems. You might find it helpful to
view the PPP Log screen (see page 21).
