the digit map, the device stops collecting digits and
establishes a call with the collected number.
The digit map pattern can contain up to 52 options (rules),
each separated by a vertical bar (|). The maximum length of
the entire digit pattern is 152 characters. The available
notations include the following:

[n-m]: Range of numbers (not letters).

. (single dot): Repeat digits until next notation (e.g., T).

x: Any single digit.

T: Dial timeout (configured by the TimeBetweenDigits
parameter).

S: Short timer (configured by the TimeBetweenDigits
parameter; default is two seconds) that can be used when
a specific rule is defined after a more general rule. For
example, if the digit map is 99|998, then the digit collection
is terminated after the first two 9 digits are received.
Therefore, the second rule of 998 can never be matched.
But when the digit map is 99s|998, then after dialing the
first two 9 digits, the device waits another two seconds
within which the caller can enter the digit 8.
An example of a digit map is shown below:
11xS|00T|[1-
7]xxx|8xxxxxxx|#xxxxxxx|*xx|91xxxxxxxxxx|9011x.T
In the example above, the last rule can apply to International
numbers: 9 for dialing tone, 011 Country Code, and then any
number of digits for the local number ('x.').
Note:

For ISDN interfaces, the digit map mechanism is applicable
only when ISDN overlap dialing is used (ISDNRxOverlap is
set to 1).

If the DialPlanIndex parameter is configured (to select a
Dial Plan index), then the device first attempts to locate a
matching digit pattern in the Dial Plan file, and if not found,
then attempts to locate a matching digit pattern in the Digit
Map rules configured by the DigitMapping parameter.

For more information on digit mapping, see 'Digit Mapping'
on page 541.
Defines the maximum number of collected destination number
digits that can be received (i.e., dialed) from the Tel side
(analog) or for digital, when ISDN Tel-to-IP overlap dialing is
performed. When the number of collected digits reaches this
maximum, the device uses these digits for the called
destination number.
The valid range is 1 to 49. The default is 5 for analog and 30
for digital.
Note:

Instead of using the parameter, Digit Mapping rules can be
configured.

For FXS/FXO interfaces: Dialing ends when any of the
following scenarios occur:

Maximum number of digits is dialed

Interdigit Timeout (TimeBetweenDigits) expires
