The Alarm Filters (Toll Fraud Detection)
9.7. Real Time Variables
Alarm Filter Clues can also include Real-Time variables that monitor the
VIP's internal clock and calendar.
Real-Time variables do not use the Alarm Filter Format, or monitor the
contents of the call record. When Real-Time variables are used, the VIP
will check its internal clock and calendar as each call record is received.
If the time and/or date matches the Clue deﬁnition, the call is ﬂagged and
counted. The VIP's internal clock, rather than the contents of the call
record, determines whether the record is counted. The following Real-Time
variables can be used to monitor the internal clock and calendar.
Note: Real Time variables are always entered as lowercase
t Time: Tells the VIP to determine the time each record is received.
The time is entered in "HH:MM" format, where HH is the hour
(00 - 23), and MM is the minute (00 - 59).
w Day of the Week: Tells the VIP to determine the day of the week
when the record is received. The day of the week is entered as a single
digit, where 1 = Sunday, 2 = Monday, 3 = Tuesday, 4 = Wednesday,
5 = Thursday, 6 = Friday, and 7 = Saturday.
d Date: Tells the VIP to determine the date the record is received. The
date is entered in "MM/DD" format, where MM is the month
(01 - 12) and DD is the date (01 - 31).
Example 1: To create an Alarm Filter Clue that will count call records
received on Sunday, match parameters would be deﬁned as w=1. Where w
is the Real-Time variable for the day of the week, and 1 indicates Sunday.
Example 2: To create an Alarm Filter Clue that will count call records
received after 6:00 pm (18:00) or before 7:00 am (07:00), match parameters
would be deﬁned as follows:
Where t is the Real-Time variable for the time, and + is the logical OR.
• Real-Time variables are not deﬁned in the ﬁlter format.
• The match parameter deﬁnition can include both Real-Time
variables and regular variables, as well as logical and relational
• Real-Time variables function independently from the Time/Date
Stamp. The Time/Date Stamp does not have to be enabled in
order for the Real-Time variables to function.
• Values from the internal clock/calendar are not included in the
call record, unless the Time/Date Stamp is enabled.
