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 record structure.

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 as follows.

1. Access command mode as described in Section 17.1. When the Main Menu appears, type 1and 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 recordsand the previous format are displayed in the following order:

Data Records (If available)Previous Format (If available)

 Enter new format at cursor. <Space><Enter> to clear.                   Use upper case letters for fields,                   '-' between fields

Figure 8.3:  Data Filter Format Definition Example

1                     From the Main Menu, type 26and press [Enter] to access the Data Filter selector menu. From the selector menu, type 1(for Data Filter 1) or 2(for Data Filter 2) and then press [Enter]. The Data Filter Configuration menu will appear (Figure 8.1).

2                     From the Data Filter Configuration menu, type 2(Define Format) and press [Enter]. The Data Filter Format definition menu will appear as shown in Figure 8.2.

3                     The Data Filter Format definition menu will show three sample PBX records, followed by the previous format definition (if available).  Although the structure will differ for each type of PBX, call records will look something like those shown in Figure 8.2. Examine the call records to locate the field location(s) you intend to monitor.

4                     Define the Data Filter Format: The prompt at the bottom of the menu is used to define the Data Filter.


a) Press the dash key to indicate a field position that you do not need to monitor.  In the last line in Figure 8.3, dashes have been entered in the first three fields of the call record.

b) When you reach a field that you need to monitor, type any uppercase letter from A to Z to assign that variable to the position. For example, to assign "A" to represent the first seven digits of the number dialed, enter seven A's (AAAAAAA) as shown in Figure 8.3. The same variable is repeated for each position in the field. It is not necessary to define variables in alphabetic order.

c) When you reach the end of the call record, or the last position you need to monitor, press [Enter]. The Data Filter Format will be saved, and NetLink II will return to the Data Filter Configuration menu.
