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 page 74.
Transformation Keywords
Order of Transformations
These transformations are always performed in the following order (the order in which the transformations are
entered in the dialing plan is not significant):
prestrip > poststrip > pre > post > replace
\a Regular
expression rules Wildcard for any single alphanumeric character.
[digit-digit] Regular
expression rules A digit within the specified range.
[character-
character] Regular
expression rules A character 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 Bria 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, Bria 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.
