Name Description
Digit (Number)
transformation
Number Transformation on each T1/E1 link.
Rule format for number transformation on a single T1/E1 link:
Operated number: Operation rule set/Operated number: Operation rule set
For details about operated numbers and translation rules, see Table 5-7.
Note: The GUI shows Digit transformation. The correct term here should be
Number transformation. Although using the 4 types of operation rules, the nth digit
of the number has been been substituted or deleted, it would result to a number
transformation of the operated number. Thus, web GUI should be changed to
Number transformation.
Table 5-7 Operated Numbers and Translation Rules
Operated Number
The following four types of operated numbers exist:

InCPN: Operates the calling numbers of calls from ISDN.

InCDPN: Operates the called numbers of calls from ISDN.

OutCPN: Operates the calling numbers of calls to ISDN.

OutCDPN: Operates the called numbers of calls to ISDN.
Operation Rule Set
There are four types of operation rules: matching rules, substitution rules, insertion rules, and
deletion rules.
The operation rule set is a combination of the four types of rules. If the user does not set a
matching rule in the operation rule set, the operation applies to all numbers corresponding to the
operated number.
Different types of rules are separated by a slash. Rules are executed in sequence from left to
right.
Matching Rule
Matching rule CnSmmm or C-nSmmm, where n is an integer greater than or equal to 1, and
mmm is a number string.

CnSmmm: Matches the number string mmm behind S from left to right, starting from the nth
digit of the number on the left.

C-nSmmm: Matches the number string mmm behind S from right to left, starting from the
nth digit of the number on the right.
Replacing Rule
Replacing rule RnSmmm or R-nSmmm, where n is an integer greater than or equal to 1, mmm is
a number string, and Y is assumed to be the length of mmm.

RnSmmm: Replaces the number string of the Y
th
digit starting from the left nth digit of the
number with the number string mmm behind S from left to right.

R-nSmmm: Replaces the number string of the Y
th
digit starting from the right nth digit with
the number string mmm behind S from right to left.
Inserting Rule
Inserting rule InSmmm or I-nSmmm, where n is an integer greater than or equal to 1, and mmm
is a number string.

InSmmm: Inserts the number string mmm behind S from left to right into the number of the
Y
th
digit starting from the left nth digit.

I-nSmmm: Inserts the number string mmm behind S from right to left into the number of the
Y
th
digit starting from the right nth digit.
Deleting Rule
Deleting rule DnSy or D-nSy, where n is an integer greater than or equal to 1, and y is the
number of digits of the number string.

DnSy: Deletes the number of the Y
th
digit, starting from the nth digit on the left.

D-nSy: Deletes the number of the Y
th
digit, starting from the nth digit on the right.
