Automatic Route Selection
If more than seven digits have been dialed after the 1, the 1+7 Tables are
eliminated. The next three digits following the 1 are compared to the 3-digit area
codes in the Area Code Tables and the first three digits of the 6-Digit Tables; any
unmatching tables are eliminated. If there are no matches, the Default Toll Table is
selected.
If there are matching tables, the next three digits are compared to the second
through ninety-ninth entry in the remaining 6-Digit Tables. If there is only one
match, that 6-Digit Table is used. If there is more than one match, the lowest
6-Digit Table is used. If there are no matches and there are no area code tables
left, the Default Toll Table is selected. If there are no matches and there are Area
Code Tables that have not been eliminated, one of the Area Code Tables is
chosen. If there is one table left, it is used. If there is more than one table, the
lowest one is used.
Figure 1 is a flowchart that shows how a table is selected.
