ISDN overlap dialing). 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.
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.').
Notes:

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 278.
Defines the maximum number of collected destination number digits
that can be received from the Tel side when Tel-to-IP ISDN 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 value is 30.
Note: Instead of using this parameter, Digit Mapping rules can be
configured.
Defines the time (in seconds) that the device waits between digits
that are received from the PSTN or IP during overlap dialing.
When this inter-digit timeout expires, the device uses the collected
digits to dial the called destination number.
The valid range is 1 to 10. The default value is 4.
