Web Browser Navigation
Issue 1 April 2005 73
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, this constraint is relaxed in the Web
browser.
The frame in which a Web page displays sits flush with both the left and right sides of the
display. Pixel 319 is the last horizontally addressable pixel, and pixel 239 is the last vertically
addressable pixel.
The Web browser uses the right side of the display for navigation controls. These controls do
not appear in any other IP telephone application.
A maximum number of 96 lines per card is supported. A line corresponds to text rendered on
the screen that spans the row between the left and right side Feature buttons.
For deck storage, 6.5 Mbytes of memory is allocated to the Web browser.
Web Browser Navigation
Web screen navigation is accomplished as follows:
● Use the Feature buttons to the left of the display to select items/lines on the screen.
● Use the Feature buttons to the right of the screen for navigation.
● One link is permitted per line. To activate a link, press the left Feature button associated
with a particular display line.
● Use Feature buttons to select an option.
● Use Feature buttons to focus on a text entry box, to allow entry of text.
● Use the softkeys on the bottom of display for navigation as appropriate.
● Also use the hard Page Left and Page Right buttons for navigation. The Page Left button
takes the user to the previous card. The Page Right button takes the user to the next card
only if it is available in the history stack.
● Horizontal scrolling is not supported for any line other than the top display line.
See Icons for Navigation Control
for additional information about establishing navigation
controls.
