1.1 General Features
Level-6 Excepted Code Table
[Explanation]
If your Toll Restriction Level is 6;
a)
You cannot make a call whose toll call number is "201," because the number whose
second digit "0" is one of the Denied Codes for Level 6.
b)
You can make a call whose toll call number is "130." Though the number whose first
digit "1" is one of the Denied Codes for Level 6, the number "130" is one of the Excepted
Codes for Level 6. The Excepted Codes override the Denied Codes.
