enable the Alarm Filter, enter Command Mode and type ^B65,2 [Enter].
7.2.3. Logical and Relational Operators
Variables and operators are combined to form parameters. Variables are the uppercase letters A
through Z defined in the Alarm Filter Format. Relational and logical operators are described in
the table below.
Operator Definition
> Greater Than
< Less Than
>= Greater Than or Equal To
<= Less Than or Equal To
~ Not. Can also precede any other
comparison operator (e.g. ~<, Not

() (Parentheses) Used to Combine
Operations
+ Logical OR
* Logical AND
7.2.3.1. Logical AND/OR Conditions
Logical AND/OR conditions can be created in the Alarm Clue definition by including the AND
operator "*" (asterisk), or the OR operator "+" (plus sign).
Logical AND Conditions
The AND operator (*) links parameters in a manner where two or more conditions must all be
true, in order for the call to be counted as an Alarm Record.
Example Assume the variable "A" represents the field for the number dialed, and "B"
represents the field for the extension number. To define an Alarm Clue named "ALL" that
generates an alarm if 99 calls are placed to 555-1111 from extension 013, type the following:
^B81,ALL\99\A=5551111*B=013 [Enter]
The Alarm Clue "ALL" would only count calls that are placed to 555-1111 AND placed from
extension 013. Calls to 555-1111 from extension 086 would not be counted, and calls to 555-
2222 from extension 013 would also not be counted.
