Toll Restriction

Toll Restriction is a system programmable feature that can prohibit certain extension users
from making unauthorized toll calls.
Every extension is programmed to belong to one of 5 classes of service (COS). Each COS is
programmed to have a toll restriction class for day mode, night mode and lunch mode.
There are 5 toll restriction COS numbers available. Toll restriction COS number 1 is the
highest class and the COS number 5 is the lowest. That is, COS number 1 allows all toll
calls. COS numbers 2 through 5 are used to restrict calls by combining pre-programmed
deny and exception codes shown in the table on the next page.
Denied Codes
An outgoing outside call made by an extension with a toll restriction COS number between 2
and 5 is first checked against the assigned denied codes in program [302]-[305].
If the first digits of the dialed number (not including the line access code) are not found in
the class, the call can be made. Each class can store up to 20 denied codes, each consisting
of 11 digits.
Exception Codes
These codes are used to override a programmed denied code. A call denied by the denied
codes is checked against the selected exception codes assigned in program [306]. If a match
is found, the call can be made.
Up to 80 exception codes, each consisting of 11 digits, can be stored. The available number
of codes depends on the COS number.
• Emergency numbers, such as the police or fire station, should be stored in program

• If a stored Host PBX access code in program [403] "Host PBX Access Codes" or a stored
carrier code in program [300] "Carrier Excepted Code Assignment" is found in the dialed
number, the subsequent telephone numbers will be checked for toll restriction.
• The interdigit timer assigned in program [208] "Interdigit Time" applies until the toll
restriction check is completed. When the timer expires, an outside outgoing call will be
disconnected while dialing, if "Enable" was selected in program [211] "No Dial
Disconnection".
• The toll restriction class for a station locked extension can be assigned in program [312]
"Toll Restriction – Station Lock Boundary Class" so that even a station locked extension
can make a local call, etc.
