## Physical Attributes

The IP telephones that support the Web browser have these characteristics:

- Six Line buttons are available for Web applications on the 9630. Three Line buttons are available for Web applications on the 9620.

NOTE: Web authors should be aware of the possible Line Buttons on the right side of the display, and should design their pages to align Web page text as necessary.

- The top display area consists of a Top Line, a Title Line, and a Prompt Line for messages, text entry prompts, and page titles.
- The bottom display line presents the available softkey selections. Four softkeys can be displayed at one time.
- Each telephone has a navigation cluster consisting of:

- Left and Right navigation buttons to navigate back to a previous page and forward to another page, if one exists,
- Up and Down navigation buttons to scroll up and down, one line or one page at a time, and,
- An OK button with the same functionality as a call appearance (Line button). The OK button provides an alternate way to select a line, a field, or an item.

- Text is in black characters when displayed against a white or light gray background. Text is in white characters when displayed against a black or dark gray background.
- When this document states that an area is selected or highlighted, this means the area is displayed in reverse video with a black background and white characters. The content of the area is otherwise unchanged.

The browser uses an HTTP client to communicate with Web servers. The browser supports WML 1.3 (WML June 2000). For more information, see wapforum.org.

The Web browser renders pages with spaces before the XML prolog. The strict rules of XML specify that pages with any characters before the XML prolog, including spaces, are invalid and should be rejected. However, many WML pages available on the World Wide Web contain such spaces. To facilitate compatibility with existing content, the Web browser relaxes this constraint.

The frame in which a Web page displays sits next to the left scroll bar area and flush with the right side of the display. The telephone determines the last horizontally addressable pixel and the last vertically addressable pixel.

A maximum number of 96 lines per card is supported. A line corresponds to text rendered in the usable area of the display screen that contains application lines.

For deck storage, 3.5 Mbytes of memory is allocated to the Web browser.
