Pattern
Valid Content
The content for a pattern follows the digit map rules of RFC 2705, supplemented by the rules for regular
expressions. Where there is an overlap between the digit map and regular expression rules, the digit map rules
apply. For this reason, there are some special cases, included in the table below.
The following table describes the most common elements. As mentioned, all regular expression elements are
supported.
Timers
There are two timers:
• T timer is 4 seconds.
• The long timer is 20 seconds.
These timers are used in input comparison, as described in “How the Input Is Processed” on page60.
Element Origin Description
0 1 2 3 4 5 6 7 8 9 Literals Literal digits, used as is.
# * a to z Literals Literal characters, used as is.
Special cases:
• The literal x character is represented by \x.
• The literal t character is represented by \t.
x Digit map rules Wildcard for any single digit, 0 to 9.
\a Regular
expression rules Wildcard for any single alphanumeric character.
[digit-digit] Regular
expression rules A digit wit hin the specified range.
[character-
character] Regular
expression rules A chara ct er within the specified range.
[digit1, digit2,
digit3] Regular
expression rules One of the characters in the collection.
. Digit map rules Repeat the last element 0 or more times. For example, xxxx. means repeat the last x 0 or
more times, which means this pattern matches three or more digits (not four or more
digits)! Use of this element results in a pattern with “minimum requirements”.
T Digit map rules A timeout period will take place before automatic dialing starts.
The T timer forces eyeBeam to wait after a match is made. This timer should always be
included in , and situations:
• Any pattern that uses the . (dot). For example, if the pattern is xxxx. then adding a
timer lets you type three or more digits. If there is no timer, then as soon as you type
three digits, eyeBeam makes the match as soon as you type three digits.
• Any dialing plan that has two patterns that are similar in elements but different in
length. For example, if one pattern is xxx and the other pattern is xxxxxxx, then
adding the timer lets you continue typing past three digits, in order to get a match on
the second pattern.
In this situation, the T timer should be included in the shorter pattern.
