Using Carrier codes
A multi-digit Carrier access code contains an Equal Access Identifier Code (CAC) followed by a
Carrier Identification Code (CIC). The CIC identifies the carrier that handles the call. The Carrier
Access Code table stores the CAC digit pattern that you define for your region.
In most cases it is not necessary to change the default values.
About Carrier access codes
Here are some general points about carrier access codes:
• You can define up to five carrier codes.
• Two entries will be pre-defined in North America, but you can remove these defaults.
• Each entry consists of an equal access identifier code prefix (one to six digits) and a carrier
identification code length (one digit, 1 to 9).
• Each entry is identified by the prefix digits themselves.
