1. A user clicks the Get Link menu item to view an attachment on a BlackBerry® device.

3. The BlackBerry Dispatcher sends the request to the BlackBerry MDS Connection Service over port 3200.

4. The BlackBerry MDS Connection Service creates an HTTP session for the user and sends the request to the web server.

The BlackBerry MDS Connection Service retrieves the requested content and sends it to the BlackBerry Attachment Service.

5. The BlackBerry Attachment Service extracts the content, layout, appearance, and navigation information from the

attachment and organizes, stores, and links the information in a proprietary DOM in a binary XML style.

6. The BlackBerry Attachment Service formats the attachment for the BlackBerry device and converts it to UCS format.

The formatting is based on the request for content (for example, page and paragraph information, or search words) and the

available BlackBerry device information (for example, screen size, display, or available space).

7. The BlackBerry Attachment Service sends the converted attachment to the BlackBerry MDS Connection Service using HTTP.

8. The BlackBerry MDS Connection Service sends the first 250 KB of content to the BlackBerry Dispatcher over port 3200.
