Example: How does a WAP page get to your Ascom Eurit 4000?

1. You press the

key and this activates the WAP browser on your Ascom Eurit 4000.

Your Ascom Eurit 4000 dials the number of your ISP (see "Number" in the ISP access

data in the "Installation/Internet connections" menu) and establishes the connection

to the ISP. Your Ascom Eurit 4000 then sends your user name and password to the ISP.

If the user name and password are correct, then the ISP is ready for requests from your

Ascom Eurit 4000.

2. After you have entered a WAP address on your Ascom Eurit 4000, the Ascom Eurit

4000 sends a data packet to the Internet via ISP. The data packet has a destination

address, namely the gateway address (e.g. 195.058.110.201), as well as a content, the

required WAP address (e.g. wap.eurit.com).

3. As soon as the data packet has found the WAP gateway, the data packet is unpacked.

The WAP gateway next locates the server which contains the required WAP page.

4. The server containing the data for wap.eurit.com sends those data back to the WAP

gateway.

5. Once the WAP gateway has converted the data into a form which the WAP browser of

your Ascom Eurit 4000 can understand, it sends the data back via ISP to your Ascom

Eurit 4000.

The display of your Ascom Eurit 4000 shows the contents of the WAP page "eurit.com".
