8, <:1212>xxxxxxx This is example is useful where a local area code is required by the

carrier but the majority of 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 transmitting 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, 1 900 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 United States. After the user press 9, an external dial tone sounds.

any number that starts with 011, as in an international call from the United States.

• Informational numbers

( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9]

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.
