8.7. Data Filter Definition Examples
When designing your Data Filter, be aware that the record format will differ
from those shown in the examples. When deﬁning the Data Filter Format
and Match Parameters the following factors should be considered:
• Exact Match: Alphanumeric values in parameter deﬁnitions must
exactly match those found in the call record. If the record lists the
time as "09:00", then the parameter deﬁnition must also list time as
"09:00" (rather than "0900" or "9:00".)
• Number of Characters : For any given variable, the number of
characters speciﬁed in the Data Filter Format must exactly match the
number of characters indicated in the Match Parameters deﬁnition.
For example, if the ﬁlter format deﬁnes "B" as the ﬁrst seven
characters of the number dialed, then the parameter deﬁnition must
account for all seven characters.
• Cumulative Effect: Each time a Data Filter clue is deﬁned,
NetLink II will add the new parameter to the existing deﬁnition. When
multiple clues are deﬁned, an OR condition is created. If the call
record matches a deﬁned clue, the record is then stored or rejected as
indicated by the Data Filter Action.
• Searching for Operator Characters: When searching for a string
that contains a space (or any character that is also used as an operator,)
a backslash (\) must precede the space or operator. For example, to
search for "***Error***", match parameters would be deﬁned
as "\*\*\*Error\*\*\*". Likewise, to search for "hello
there", match parameters would be deﬁned as "hello\ there".
• Variable Case: When deﬁning and using variables, take care to use
the correct case. Real Time variables are always entered as lowercase
characters; regular variables are always entered as uppercase
