15 is the number to add immediately after the string denoted by [5,3] - in other
words, 15 is added after (i.e. to the right of) the digits 202.
2. The first seven digits from the left are removed from the original number, by entering
"7" in the 'Stripped Digits From Left' field.
In this configuration, the following manipulation process occurs: 1) the prefix is calculated,
020215 in the example; 2) the first seven digits from the left are removed from the original
number, in the example, the number is changed to 8888888; 3) the prefix that was
previously calculated is then added.

Digit Mapping

The device collects digits until a match is found in the user-defined digit pattern (e.g., for
closed numbering schemes) or until a timer expires (e.g., for open numbering schemes). If
a match is found (or the timer expires), the digit collection process is terminated.
The maximum number (up to 49) of collected destination number digits that can be received
(i.e., dialed) from the Tel side by the device can be defined (using the parameter
MaxDigits). When the number of collected digits reaches the maximum (or a digit map
pattern is matched), the device uses these digits for the called destination number.
Dialing ends (and the device starts sending the digits) when any of the following scenarios
occur:
Maximum number of digits is received.
Inter-digit timeout expires (up to 10 seconds). This is defined by using the parameter
TimeBetweenDigits. This is the time that the device waits between each received digit.
When this inter-digit timeout expires, the device uses the collected digits to dial the
called destination number.
Pound (#) key is pressed.
Digit map pattern is matched.
Digit map (pattern) rules are defined by the parameter DigitMapping. If the digit string (i.e.,
dialed number) matches one of the patterns in the digit map, the device stops collecting
digits and establishes a call with the collected number.
