International Prefix and Second Dial Tone


BN : AXS-008 July 31, 1995

There are several countries in which an International Prefix is dialed and before the call proceeds a second dial tone must be received. The AXS dialer can be programmed to satisfy this requirement by dialing the prefix and then returning dial tone to the system so that dialing can proceed. A match in the primary table of the International Prefix launches a program to return dial tone and then a continual search of the secondary table produces a match that halts the program from the primary match and executes the program associated with the secondary match.

Example: User dials 00 for international calls and must wait for second dial tone

Program would look similar to the following;

Primary Table Entries 00 - 19

Secondary Table Entries 003 - 18, 004 - 18, 00? - 15

Program 19 100200,75,701,99

Program 18 810102, 6000, 93, 95, 99

Program 15 6401,571001,97,91,5825,97,90,5008,97,810102,6000,93,99

Program 21 90,92,75,701,99

Bin 01 Should not contain code of 00 as it has already been dialed with the launch of Program 19 from the Primary Table match

The above programs can be used as starting points for programs that require the return of second dial tone and modified to meet your specific requirements.
