The Data Filters
8.2. Defining the Data Filter Format
The Data Filter Format describes the location of various "ﬁelds" within
each call record. Proper deﬁnition of the Data Filter Format tells NetLink II
where to look, in order to determine if a record should be omitted or stored.
Different types of PBX units will produce records with slightly different
data structures. In order to deﬁne the Data Filter Format, you must ﬁrst
examine several records from your PBX in order to determine the
After the format has been determined, the next step is to assign variables to
the ﬁelds you intend to monitor. The Data Filter Format allows deﬁnition
of up to 26 variables (the uppercase letters A through Z), which are used to
indicate speciﬁc record ﬁelds or locations. These variables are used later
when deﬁning Data Filter Clues. To deﬁne the Data Filter Format, proceed
1. Access command mode as described in Section 17.1. When the Main
Menu appears, type 1 and press [Enter] to access the Status Displays
Screen. Check the Status Screen for the input port that you intend to
ﬁlter (Serial PBX Port or PBX IP Port), and make certain the Time/
Date Stamp is Off at that port. The Port Conﬁguration menus are used
to enable/disable the Time/Date Stamp at each port.
Note: When the Time/Date Stamp is On, ﬁeld locations will be
altered. The Time/Date Stamp appends extra characters to each
record. This may cause errors in the Data Filter Format. Disable
this feature prior to storing records that will be used when deﬁning
the Data Filter Format.
2. Press [Esc] to return to the Main Menu. Allow the NetLink II to
collect several PBX records.
In order to assist the user during format deﬁnition, several data records
