Configuring Dial Plans 3 Acceptance and Transmission the Dialed Digits When a user dials a series of digits, each sequence in the dial plan is tested as a possible match. The matching sequences form a set of candidate digit sequences. As more digits are entered by the user, the set of candidates diminishes until only one or none are valid. When a terminating event occurs, the WRP400 either accepts the user-dialed sequence and initiates a call, or else rejects the sequence as invalid. The user hears the reorder (fast busy) tone if the dialed sequence is invalid. The following table explains how terminating events are processed.

The dialed digits exactly match • If the sequence is allowed by the dial plan, the one sequence in the dial plan. number is accepted and is transmitted according to the dial plan. • If the sequence is blocked by the dial plan, the number is rejected. A timeout occurs. The number is rejected if the dialed digits are not matched to a digit sequence in the dial plan within the time specified by the applicable interdigit timer. • The Interdigit Long Timer applies when the dialed digits do not match any digit sequence in the dial plan. The default value is 10 seconds. • The Interdigit Short Timer applies when the dialed digits match one or more candidate sequences in the dial plan. The default value is 3 seconds. The user presses the # key or the dial softkey on the phone display. • If the sequence is complete and is allowed by the dial plan, the number is accepted and is transmitted according to the dial plan. • If the sequence is incomplete or is blocked by the dial plan, the number is rejected.
