Enable Special SRA Area Code Tables
Description:
The four special area code tables must first match a dialed area code and then match the
dialed office code with office code entries in the matched table. With a complete match
found, the system routes the call over the line group that you have assigned to the
matched office code in the matched special area code table.
NOTE: When programming the special area code tables, note that all office code
entries are defaulted to line group 1; therefore, to minimize programming
effort, assign those codes with the fewest entries to line groups 2 through 4.
For example: if you are programming for code entries 200 through 299, and
codes 000 through 209 requires one line group while codes 210 through 299
requires another line group, leave line group 1 assigned to the larger quantity
of entries that require the most programming effort (210-299)and reprogram
the line group for the smaller quantity of entries.
