7. PROGRAMMING TOLL RESTRICTIONS
Toll restrictions allow you to place restrictions on outbound toll calls, per tenant group and account code. Perform
the following steps.
1. Set up Class of Services (COSs).
2. Set up the digit interval from 1 to 100, per tenant group.
3. Program the account code length.
4. Program the account code passwords (up to 600).
While you are programming in PC-DBA, the system saves your changes in the working directory residing on the
laptop. While it may appear that you have re-programmed the switch, the system does not update the switch
database with your changes until you perform a SEND command from the laptop.
For further details on the SEND command, see Section 2.1.4.4, F4 – Send .
7.1 Class of Service and Digit Intervals
The DX-80 provides sophisticated monitoring of outbound digits dialed by callers on CO lines. You can assign
COSs for a broad range of call control. For example, if a digit or range of digits dialed on a CO line is inconsistent
with the dialing extension’s or CO line’s class of service, the system denies the call. You can apply this calling
COS criteria 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 can contain 10 digits in the “From” column
and 10 digits in the “To” column. These fields allow you to specify a range of digits in a truth-table fashion known
as digit intervals. You then set extension COS and CO line COS per table entry as Y/N (e.g., does this table entry
apply to this COS? Yes or No.). You specify two conditions for extension and CO line COS assignments, per
table entry: Day mode and Evening mode. This allows you to assign each table entry to each COS differently for
these day or evening modes.
An example of a table entry may be as simple as “From 0,” “To 0.” The result of this truth table is that the system
monitors calls associated to this COS for only the first digit dialed. If that digit is “0,” the system allows the call
and no further restriction monitoring takes place.
Another example is a table entry of “From 1813412,” “To 1813450.” In this case, the system monitors calls in this
COS sequentially for the first seven digits dialed, or until the caller enters the first digit inconsistent with this
setting. Thus the system denies a call dialed as 1813410 as soon as the caller enters the digit “0”. The system
allows the caller to dial 1 any digits.
The following conditions apply to assigning class of service and digit intervals.
• Digit interval 001 is programmed as: From “0,” To “#” (this allows all digits to be dialed).
• You can program up to 100 digit intervals, 10 per tenant group.
CAUTION
If PC-DBA is set to U-Save, your database changes reside only on
your laptop. When you have finished making all changes to the data-
base, perform a SEND operation to download the new database to the DX-80 switch.
