摘要：
A routing table enables a particular long distance carrier for a particular long distance or international destination at a particular time. Different entries in the routing table correspond to different days and times for different long distance and international destinations. If a subscriber dials a number corresponding to the information in the routing table, the carrier corresponding to that information is used to carry the call, instead of the subscriber's default carrier. If the subscriber dials a number that does not correspond to an entry in the routing table, then the default carrier is used to carry the call.
