ONT Product Information Guide
The following is an example of a digit map used with SIP mode 1:
*x{20} | #x{20} | 411 | 911 | [01235678]x{20} | [49] ([^1]x{19} |
1[^1]x{19})
This example:
• Allows for up to 20 digits to be entered following * or # for service codes
• 411 or 911 can be entered and digit map collection will stop immediately.
• Allows a dialed number (without a service code) of up to 20 digits, with
exclusions to make sure the different patterns are unique for 411 and 911.
• This example forces the subscriber to use the enter key or wait for timeout to dial
a simple service code or phone number (except for 411 or 911).
• The interdigit timeout with this Digit Map should be configured to 4 seconds
(normally it is 16 seconds).
The following is an example of a digit map used with SIP mode 2:
( ( * | 11 ) ( 67 | 82 ) ) SRI# {0,2} ( ( * | 11 ) ( 70 ) ) S I# ? (
101xxxx ) ? ( ( * | 11 ) 52 ) S I# ? ( ( * | 11 ) ( 88 | 90 ) ) R I#
? ( ( ( * | 11 ) ( [23]xx | [014]x | 5[^2] | 6[^7] | 7[^0] | 8[01345679]
| 9[^0] ) ) S I# | ( 0T | 00 | 011?[2-9]x{0,14}T | [01] ( [2-8] 11 |
(911)E | [2-9] ( [^1]x{8} | 1[^1] x{7}) ) | [2-8] 11 | (911)E | [2-9]
( [^1]x{5} | 1[^1] x{4}) | [2-9] [^1]?T ) )
I The I modifier represents the insertion of a special digit character
(such as #) into the collected digit string immediately following the
substring that matches the pattern element that is followed by the
I modifier. The inserted character is specified immediately
following the I in the pattern.
E The E modifier specifies the substring that matches the pattern
element before it as an emergency call. The pattern element
generally is a sequence of pattern elements enclosed in
parentheses.
R The R modifier specifies that a recall dial tone should be output
after a particular pattern is performed.
S The S modifier specifies the substring that matches the pattern
element before it as service code that may be of interest to the user
agent. The pattern element generally is a sequence of pattern
elements enclosed in parentheses. This use of this symbol is not
supported in SIP mode 1.

Note 1 — Alphabetic symbols in the ONT digit map are not case
sensitive.
Note 2 — The digit_map SIP parameter is a required parameter; it has
no default value. A digit map must be customized for each SIP
implementation based on the features of the SIP server in the network.
