6.2. Defining Data Filter Parameters
The Data Filter Parameters describe specific criteria that PollCat III uses to determine whether
call records will be stored or omitted. Note that Command ^B42 has a cumulative effect. Each
time ^B42 is invoked, its argument (parameters) are added to the existing Data Filter
The argument of Command ^B42 will usually include the following components:
·A variable (any letter from A through L) from the Data Filter Format, which designates the
field(s) to be monitored.
·A logical or relational operator (see Section 6.4).
·A description of the call characteristics used as the criteria for storage or rejection.
To define the Data Filter Parameters, proceed as follows.
1. Enter the Command Mode and invoke Command ^B42 using the following format:
Where parameters is a description of the characteristics of the type of call you want to
Example: If the Data Filter Format assigns the variable "C" to represent the field for the
call time, and you want to store only records for calls placed before 6:30 pm (18:30), then
Data Filter Parameters would be defined as follows:
2. To display the Data Filter Parameters, type ^B43 [Enter].
3. To define complex Data Filter Parameters that use multiple variables or AND/OR
conditions, please refer to the examples in Section 6.6.
4. To clear all Data Filter Parameters, type ^B42 [Enter].
CAUTION: Data Filter Parameters that have been cleared cannot be recovered.
The Data Filter Parameters must be redefined manually, unless the
configuration has been saved as described in Section 8.
6.3. Enabling the Data Filter
After Parameters are defined, the Data Filter must be enabled. Enter the Command Mode and
type ^B56,2 [Enter].
