Some Common Toll Restriction Examples
Note that the following 4 examples can be simultaneously programmed in the same system – just don’t rein-
itialize the Toll Restriction Tables in examples 2-4.
Example 1: Allowing Only Local Calling
Allow users to dial only 7-digit and 10-digit local numbers. All 1 + 7 digit, 1 + 10 digit, 0+, and Equal
Access dialing is restricted.
1. Make sure the following are disabled:
• 3512-01: Allow 0 + XXX Operator Assisted Dialing
• 3512-02: Allow 011 + XXX International Dialing
• 3512-03: Allow 101x Equal Access Dialing
2. For Toll Level 1, be sure the following tables are set as allow tables with no entries. (This setting blocks
all calls of the type specified by each table.)
• 352x-1010-XXX / Local XXX (Equal Access Dialing)

3. In 355x-XXX / TBL-B-XXX (NPA/NXX Dialing 3-Digit Table), make the table a deny table with no
entries. (This will allow unrestricted dialing of 7-digit and 10-digit local numbers.)
4. In 356x-XXX-XXX / TBL-B XXXXXX (NPA + NXX Dialing 6-Digit Table), make the table a deny table
with no entries.
Example 2: Setting Up 10-Digit Local Calling
Restrict 1 + 203 calls in a neighboring (foreign) area code, but allow 203 10-digit calls in the home area code.
1. For Toll Level 2, be sure Toll Restriction Tables 352x through 356x are deny tables with no entries. (This
will allow unrestricted dialing.)
2. In 353x-1+XXX / TBL-A XXX (NPA/NXX Dialing 3-Digit Table), add code 203.
3. In 2102-02: Station Toll Level (Day) and 2102-03: Station Toll Level (Night), assign Toll Level 2 to
extensions.
