Acronyms and Glossary
Item Definition
Card A WML card is similar to an HTML page, but WML delivers a set
(deck) of closely related cards. The complete WML page comprises a
collection of various cards, of which only one is visible on the browser
at one time. As each of the cards is labeled by a name and ID, they
can be linked together without difficulty. The WML page provider
determines the content of the card. The browser determines how
this card will be displayed (rendered).
Deck A deck can be described as a stack of cards. When the browser
downloads a WML page, it really is downloading a deck of cards but
only one card in the deck is visible at a time.
HTML HyperText Markup Language. Hyper Text Markup Language is a text-
based way of describing data for transmission over the Internet HTML
is usually used with larger, color displays.
HTTP Hypertext Transfer Protocol. Hyper Text Transfer Protocol is a protocol
that a web server and a web client use to contact each other and
request and deliver files.

W3C The Worldwide Web Consortium, which has become the key
standards body for most of the XML-related technologies.
WAP Wireless Application Protocol is an open global standard for wireless
solutions that includes WML.
WBMP WBMP is a Bitmap graphic format that is required for the integration
of graphics into WML pages.
Well formed An XML document whose tags and data are consistent with XML 1.0
syntax.
WML
Wireless Markup Language is a subset of XML that was developed for
WAP. It allows for text display on a device, card and deck
organization, navigation and linking, and state management. WML
was designed for low-bandwidth, small-display devices. As part of
this design, the concept of a deck of cards was utilized. A single WML
document (i.e., the elements contained with the <wml> document
element) is known as a deck. A single interaction between a user
agent and a user is known as a card. Multiple screens (cards) can be
downloaded to the client in a single retrieval.
WTAI Wireless Telephony Application Interface is a set of interfaces that
extend the WAE (Wireless Application Environment) to include
telephony applications.
XML 1.0
The first standard for XML syntax blessed by the W3C; establishes
basic rules for XML data, such as all tags must be closed with a slash
(/) like this: <example/> or followed by a closing tag like this:
<example>close the tag on your way out</example>.

General FAQ, Browser behavior and capabilities…
This section answers basic questions about the 4620 WML Browser and clears the
myths and misconceptions.
GEN_1 Section: GENERAL
Question What version of WML does the 4620 WML Browser support?
Answer The 4620 WML Browser supports the WML 1.2 (June 2000) release.
Sometimes this version of WML is also referred to as WML 1.3
GEN_2 Section: GENERAL
Question What is the relation between XML and WML?
Answer WML (Wireless Markup Language) is a markup language based on XML.
WML is a XML specification proposed by the Open Mobile Alliance
(http://www.wapforum.org/) and follows the XML rules and
specifications. WML uses tag pairs and attributes for all language
features.
Essentially, WML is an XML application.
Comments Good web site for WML is:
http://www.devguru.com/Technologies/wml/quickref/wml_intro.html
GEN_3 Section: GENERAL
Question Can we call the 4620 WML Browser a XML browser instead of a
WML browser?
Answer Refer above:
Since WML is an XML application, the 4620 WML browser is a XML
browser that supports WML tags.
Avaya supports industry standard WML specifications on the 4620 WML
Browser.
GEN_4 Section: GENERAL
Question In short can you summarize the capabilities of WML?
Answer WML support six key areas:
•Text presentation and layout - Line breaks, basic text formatting and
alignment are supported by WML.
•Images - WML supports Wireless Bitmap images and alignment on the
screen.
•User Input - WML supports choice lists, multilevel choice lists, text entry
and task controls.
•Cards and decks - User interaction is divided into cards. Navigation is
primarily between cards. Decks are related sets of cards and are saved
as a single file
•Navigation - WML supports the standard Internet URL naming scheme
and anchored links, allowing navigation between cards in a deck,
between decks, or between other resources on the network such as
databases.
•State and context management - WML allows for variables to be
passed between files. Instead of sending a complete string, variables can
be sent and substituted at runtime. The user agent can cache both
variables and WML files, minimizing cache hits and server requests. It is
also possible to pass variables between different cards in the same deck.

GEN_5 Section: GENERAL
Question What is HDML? Does the 4620 WML Browser support it?
Answer HDML (Handheld Device Markup Language) was first proposed in 1997
by Unwired Planet as a standard. Later on, in 1999 along with other
industry players, a new organization (wapforum.org) was formed and a
new specification, WML, was proposed.
In short, both languages have similar programming model and
functionality. Major differences are that HDML is not an XML based
language and does not have any support for a client side scripting
language such as WMLScript.
Today, very few phone.com browsers support HDML.
The 4620 WML Browser does NOT support HDML.
Comments Reference:

r.html
GEN_6 Section: GENERAL
Question What is difference between HTML and WML? What can I do with
HTML that I cannot do with WML? Which one is better?
Answer HTML is a specification that was first proposed by w3c org. HTML is not
based on an XML specification.
WML is an application of XML (EXtensible Markup Language),
Essentially WML is a stripped down version of syntactically valid HTML
with 35 strictly applied semantic tags.
HTML has well over 120 tags (three times that of WML) helping to give
its characteristically messy ad-hoc nesting syntax. Rules for HTML tag
nesting are loose.
EXtensible Markup Language (XML) presents a solution to the HTML
mess. Using XML developers can define their own markup languages
by referencing to an external DTD (Document Type Definition). The
DTD is a sequence of rules describing the markup language. However
this enforces strict rules governing language syntax in stark contrast to
HTML.
•HTML has a comparatively deep and complex nesting structure.
•HTML is not well-formed allowing tagsets to remain unclosed.
•HTML can display special Unicode characters not recognized in
WML.
© [2003] Avaya Inc. All Rights Reserved.
Page 11 of 32

•WML tags must all be in lowercase.
•WML is unforgiving of incorrectly nested tags.
HTML and WML also share a lot of features together. The WML set of
tags was designed to cover most of the functionality that could be
achieved using HTML. The list of functionality includes features such
as: Text Presentation and layout, Images, User Input (Form controls
such as choice lists, multilevel choice lists, text entry and task
controls), Navigation, Hyperlinks etc.
GEN_7 Section: GENERAL
Question Does the 4620 WML Browser support WMLScript?
Answer WMLScript is Not Supported
Comments WMLScript is a client-side similar to JavaScript. It provides basic
programmability that can be used to perform basic text and data
manipulation.
GEN_8 Section: GENERAL
Question Does the 4620 WML Browser support images?
Answer WBMP is supported in 1.8 release.
1.71 Not Supported
1.72 Not Supported
1.73 Not Supported
Release
1.8 WBMP Supported
GEN_9 Section: GENERAL
Question What happens if 4620 WML Browser support comes across a
WML page with leading blank spaces before the first line <?xml
version="1.0"?>
Answer "Although leading spaces before the first line <?xml version = "1.0"?>
is invalid and violates the XML specification, many external WAP sites
contain this error. (For more details please refer to the XML specs:
http://www.w3.org/XML/). The 4620 WML Browser will correctly render
pages with this error."
Please see below for release specific notes:
1.71 The browser will display the error “Page cannot be rendered”
1.72 The browser will display the error “Page cannot be rendered”
1.73 The browser will display the error “Page cannot be rendered”
Release
1.8 No Error. The browser will render the page as usual.
GEN_10 Section: GENERAL
Question Does the 4620 WML Browser cache pages in the browser?
Answer The 4620 WML Browser will only store the current WML file (or the
current deck of cards) in memory.
When a user tries to go back in history and if the page corresponds to
a different WML page from that corresponding to the one that is
displayed on the screen, the 4620 WML Browser will retrieve/fetch a
new copy of the page. Any user selection or text entry made by the
user will be lost.

GEN_14 Section: GENERAL
Question What is “Enhanced Local Dialing”?
Answer A new feature in 1.8 release called “Enhanced Local Dialing” can be
administered in the settings script file (46xxsettings.txt).
With Enhanced Local Dialing, you can set values such as the country
code, the international access code, the extension length within your
organization, the outside line access code, the long distance access
code, and the length of the national telephone number.
By setting these values, the phone/browser will automatically add the
necessary dial prefixes to the phone number it encounters in the WTAI
dial link on any web page.

Scripts, Common WEB Related values..
SCRIPT_1 Section: SCRIPTS
Question What is the right format to set variables in the settings file?
Answer The proper way to set a variable in a script is:
SET variable value
The following are invalid:
SET variable=value
AND
variable=value
These variables are set in the 46xxsettings.txt file.
The 46xxupgrade.scr file contains lines that instruct the 4620 to
download the settings file on bootup. The 46xxupgrade.scr file should
not be edited.
SCRIPT_2 Section: SCRIPTS
Question What are the values needed for the 4620 WML Browser in the
settings file?
Answer
System Value Name Default Value
WMLCODING “ASCII”
WMLEXCEPT “” (null string)
WMLHOME “” (null string)
WMLPORT “8000”
WMLPROXY “” (null string)
•The 4620 will not display the Web label on the softkey if the
system value WMLHOME is null.
•An HTTP proxy server is not used if WMLPROXY is null, or if
WMLPROXY cannot be resolved into a valid IP address.
•The HTTP proxy server is used for all web transactions if
WMLPROXY is resolved into a valid IP address and WMLEXCEPT is
null,
•If WMLEXCEPT is not null, the HTTP proxy server is only used for
URLs whose domains are not on the WMLEXCEPT list. A list of IP
addresses or an ip address with a wild card can be set here. For
example: SET WMLEXCEPT 1.2.*,1.3.*
•WMLCODING stands for the optional Web application Coding
Scheme, and is the “alphabet” used for encoding text queries to
the server.
•WMLEXCEPT stands for Web application HTTP proxy server
exception domains (domains for which the proxy server will not
be used), which is a list of one or more domains, separated by
commas without any intervening spaces (up to 127 total ASCII
characters, including commas).
•WMLHOME stands for the URL of the home page for the Web
application.
•WMLPORT stands for the TCP port number used for the HTTP
proxy server.
•WMLPROXY stands for the IP address, in dotted-decimal or DNS

name format, of an HTTP proxy server. If the web pages
accessed by the 4620 are completely on the customer’s intranet,
WMLPROXY, WMLPORT and WMLEXCEPT need not be set. If
WMLPROXY is null, the values of WMLPORT and WMLEXCEPT do
not matter.
SCRIPT_3 Section: SCRIPTS
Question How do I create a customized 46xxsettings.txt script file for the
4620 and other IP Telephones?
Question Is there an application or wizard available to create customized
script files for 4620 Web/WML settings?
Answer Yes, the Avaya 46xx Settings Script Wizard is available to automate
this task.
Avaya 46xx Settings Script Wizard is a PC-based (Windows) software
tool designed to help customer administrators create 46xxsettings.txt
files tailored for their specific environments and preferences.
The settings script wizard can also load any previous software release
script files (46xxsettings.scr) and will retrieve the settings/values of

A <do> tag is considered an UNKNOWN type if the type attribute for
the <do> tag is missing or the type attribute specified by the author
does not correspond to one of the acceptable types as specified in the
WML 1.3 specs. (Remember WML files are case sensitive and type
attributes must be in lower case).

Image support (WBMP Issues…)
TECH_9 Section: TECHNICAL
Question What is the memory size limit on a WBMP image?
Answer A cache of at least 32 Kbytes will be maintained in volatile memory for
image files. Any image greater than 32 Kbytes will be truncated. If
many images are contained on a card and the total memory for the
collection of images is greater than 32 Kbytes, only 32Kbytes of
images will be rendered. At the point when 32Kbytes of memory is
exhausted, all remaining images will be rendered as alt tags. For
example, if 10 images of 10 Kbytes each are contained on a card, the
first 3 images will be rendered in total, and the alt tag of the remaining
image will be presented.
Release 1.8 32 Kb max
TECH_10 Section: TECHNICAL
Question Is there a limit on the no of WBMP images per WML file?
Answer Yes. In the 1.8 release, a maximum number of 10 images up to the
memory limit of 32 KB will be retrieved per WML file. For all other
images, the alt tag will be presented.
Release 1.8 10 images
TECH_11 Section: TECHNICAL
Question What is the physical size limit on a WBMP image?
Answer A “1” pixel padding is added on all four sides to the image.
With this padding the maximum width of an image is 150 pixels (152 -
2 pixels). The maximum height is 96 lines (1534 pixels=1536-2).
Images greater than the maximums will be truncated.
Also for an image to fit in a line the max height can be 14 pixels (16-2
pixels)
