9, <:1>[2-9]xxxxxxxxx This example is useful where a local area code is required. After a user presses
9, an external dial tone sounds. The user must enter a 10-digit number that begins with a digit 2 through
9. The system automatically inserts the 1 prefix before it transmits the number to the carrier.
• Local dialing with an automatically inserted 3-digit area code:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )
8, <:1212>xxxxxxx This example is useful where a local area code is required by the carrier but most
calls go to one area code. After the user presses 8, an external dial tone sounds. The user can enter any
seven-digit number. The system automatically inserts the 1 prefix and the 212 area code before it transmits
the number to the carrier.
• U.S. long-distance dialing:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )
9, 1 [2-9] xxxxxxxxx After the user presses 9, an external dial tone sounds. The user can enter any
11-digit number that starts with 1 and is followed by a digit 2 through 9.
• Blocked number:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )
9, 1 900 xxxxxxx ! This digit sequence is useful if you want to prevent users from dialing numbers
that are associated with high tolls or inappropriate content, such as 1-900 numbers in the U.S. After the
user presses 9, an external dial tone sounds. If the user enters an 11-digit number that starts with the
digits 1900, the call is rejected.
• U.S. international dialing:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )
9, 011xxxxxx After the user presses 9, an external dial tone sounds. The user can enter any number
that starts with 011, as in an international call from the U.S.
• Informational numbers:
( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx
| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )
0 | [49]11 This example includes two-digit sequences, separated by the pipe character. The first
sequence allows a user to dial 0 for an operator. The second sequence allows the user to enter 411 for
local information or 911 for emergency services.
• Service activation codes:
[*#]xx[*#] Allows the user to dial # codes and * codes to access functions.
• Service activation codes with additional parameters:
#xx+xxxxxxxxxxx*xxxxxxxxxx Allows the user to dial a # code, followed by two 10-digit numbers.
