In some areas of North America, the local telephone company has two types or levels of toll calls,
those that require a 1+ or 0+ and those that do not (non 1-plus). Local Zone calls (non 1-plus) are toll
calls that have normal 7-digit telephone numbers. For example, in most areas callers have to dial 1-
820-6363 or 1-425-820-6363 in order to make a long distance call within the area code, but in “non
1-plus” areas, the call is placed just by dialing 820-6363. The only way to toll restrict this type of
call is to know all the telephone number prefixes which are toll calls. The Model 748 uses a 1000-
prefix (all possible prefixes) toll table to determine which prefixes are Local Zone or non 1-plus toll
calls. It will not allow calls to restricted prefixes if the user is toll restricted.
The Prefix table can be made up of either “Allowed” or “Restricted” prefixes. Your local area will
probably only have either a few “Free” prefixes or a few “Toll” prefixes. Set the sense of the table to
minimize the number of prefixes you need to enter. Any non 1+ or 0+ number dialed will be checked
against the Prefix table for a determination of “Toll” or “Local” call.

Add Prefix to table:
To add a prefix, type “2” and press ENTER . You will be prompted to enter the prefix to add, do so
and press ENTER . It will then prompt you again since it is likely you will need to restrict many
prefixes. The Model 748 allows you to add prefixes in bulk. When you are finished adding prefixes,
press
ENTER .
Delete Prefix from table:
To delete a prefix, type “3” and press ENTER . You will be prompted to enter the prefix to delete, do
so and press ENTER . The Model 748 also allows you to delete prefixes in bulk. Keep entering
prefixes to delete and press
ENTER
when you're finished.
