T
COS Number
Example of Toll Restriction programming
3-130 Features
Applicable Denied Code Classes and Excepted Codes depend on
the assigned toll restriction COS number of an extension as follows.
Denied Codes
1 None
2 Codes for Class 2
3 Codes for Classes 2 and 3
4 Codes for Classes 2 to 4
5 Codes for Classes 2 to 5
[Explanation]
COS 1: allows all calls.
COS 2: denies the 20 codes stored in Denied Code Class 2 assigned in
program [302], except all codes stored in Code numbers
01 through 80 assigned in program [306].
COS 3: denies the 40 codes stored in Denied Code Classes 2 and 3
assigned in programs [302] and [303], except the 60 codes stored
in Code numbers 01 through 60 assigned in program [306].
COS 4: denies the 60 codes stored in Denied Code Classes 2 through 4
assigned in programs [302] through [304], except the 40 codes
stored in Code numbers 01 through 40 assigned in program [306].
COS 5: denies the 80 codes stored in Denied Code Classes 2 through 5
assigned in programs [302] through [305], except the 20 codes
stored in Code numbers 01 through 20 assigned in program [306].
Here is an example to explain the procedure for Toll Restriction
programming.
1. Determining the application
Determine the dialing numbers that should be denied for COS
numbers 2 through 5. (1 is fixed and does not require
programming.)
3 Features
Excepted Codes
None
All codes from Code number 01 to 80
15 codes from Code number 01 to 60
10 codes from Code number 01 to 40
5 codes from Code number 01 to 20
