Toll Restriction - Class Of Service - Comdial DX-80 Installation & Maintenance Manual

Toll Restriction – Class of Service
The DX-80 provides sophisticated monitoring of digits dialed on CO lines. The assignment of COS (Class Of Service)
may be used for a broader range of call control than simple "Toll Restriction" implies. If a digit or range of digits dialed
on a CO line is inconsistent with the dialing extension's COS or CO Line COS, the call is denied. This calling COS
criteria can be applied to local calls, long distance calls, and specific numbers that are considered allowed in areas
where other numbers may be restricted.
The DX-80 provides a Toll Restriction table of 100 entries. Each entry may contain 10 digits in the "From" column and
10 digits in the "To" column. The From and To columns exist to apply a range of digits in a truth-table fashion known
as digit Intervals. Extension COS and CO Line COS is then designated per table entry as Y/N. (E.g., does this table
entry apply to this COS? Yes or No.) Extension and CO Line COS assignments for each table entry are provided
under the two conditions, Day and Evening mode. This allows each table entry to be assigned to each COS for CO
Lines and extensions differently for these modes of system operation.
A table entry may be as simple as "From 0," "To 0." The result of this truth table is that calls associated to this COS
are monitored for only the first digit dialed. If that digit is "0," the call is allowed and no further restriction monitoring
takes place.
A table entry of From "1813412," To "1813450" will cause calls with this associated COS to be monitored for the first
seven digits dialed or until the first digit inconsistent with this entry is dialed. A call dialed as 1813410 is denied when
the digit "0" is dialed. A call dialed as 1813419+any digits, is allowed.

Default Settings
Restriction – Toll Restriction – Digit Interval 001 – From = "0."
(Range is any digits, max. 10 in length.)
Restriction – Toll Restriction – Digit Interval 001 – To = "#."
(Range is any digits, max. 10 in length.)
Restriction – Toll Restriction – Digit Interval 002~100 – From/To = "NULL" (none).
Restriction – Toll Restriction – Digit Interval – Extension/CO Line Day/Eve COS 0 = "Y." (Range is Y/N.)
Restriction – Toll Restriction – Digit Interval 002~100 – Extension/CO Line Day/Eve COS 1-7 = "N."
Extension - Day/Eve Class Of Service = "0." (Range is 0~7.)
CO Line Day/Eve Class Of Service = "0." (Range is 0~7.)
Conditions
a) Digit Interval 001 is programmed as: From "0," To "#." (This allows all digits to be dialed.)
b) There are one hundred (100) Interval Table entries available for programming.
c) System Speed can be set to Override toll restriction.
Programming Abstract
•
Program Digit Intervals as required.
