9.8. Assigning the Alarm Filter to a Port
After deﬁning the Alarm Filter, the next step is to assign the ﬁlter to one or
more input ports. The Port Conﬁguration menus are used to assign one of
the available Alarm Filters to each port as described in Section 5.4. Note
that Alarm Filters will not function until they are assigned to a port.
9.9. Match Parameter Definition Examples
The following examples are based on ﬁctional PBX call record formats.
When designing your Alarm Filter, be aware that the record structure will
differ from those shown in the examples. When deﬁning the Alarm Filter
Format and Match Parameters the following factors must be considered:
• Exact Match: Alphanumeric values in parameter deﬁnitions must
exactly match those found in the call record. If the record shows the
time as "09:00", then the match parameters must also list the time as
"09:00", and not "0900" or "9:00".
• Number of Characters: For any given variable, the number of
characters speciﬁed in the Alarm Filter Format must exactly match
the number of characters indicated in the Match Parameters deﬁnition.
For example, if the ﬁlter format deﬁnes the variable "B" as the ﬁrst
seven characters of the number dialed, then the parameter deﬁnition
must account for all seven characters.
• Searching for Operator Characters: When searching for a text
string which contains a space or any character that is also one of the
VIP's operators (e.g. >, <, or &) a backslash (\) must precede the
space or operator. For example, to search for "***Error***", the
match parameter would be deﬁned as "\*\*\*Error\*\*\*".
Likewise, when searching for "hello there", the match parameter
would be deﬁned as "hello\ there".
• Variable Case: When deﬁning and using variables, take care to use
the correct case. Real Time variables are always entered as lowercase
characters; regular variables are always entered as uppercase
