Evaluating Call Numbers In Call Bar Groups - Avaya T3 Classic User Manual

Call bar groups
The following three programming steps are required when programming call bar groups:
1. Call number entry
In the call bar group memory slots, enter the first digits (max. 6) of the call number
to be monitored (see "Entering dialling digits in the call bar").
2. Assigning subscribers to the call bar groups
You must assign the subscribers, whose external dialling is to be monitored by the
call bar group, to the desired call bar groups (see "Programming the assignment of
subscribers to call bar groups"). A subscriber can be assigned to several or even all
call bar groups.
3. Assigning exchange lines to the call bar groups
You can specify for which exchange lines the call bar groups are to be evaluated.
This means specific exchange lines can be removed from the call bar.

Evaluating call numbers in call bar groups

The following example shows you how the system evaluates the entered numbers.
The dialled call numbers are monitored digit by digit by the call bar starting at the beginning. If dialling
of a barred number is detected, the seized dialup line is released again and the subscriber hears the
"busy" signal.
These examples assume that the subscriber (e.g. subs. 11) and the exchange line which the sub-
scriber can access are assigned to call bar group 1.
Example 1:
Subscriber 11 is to be set up so that he
•
can only make calls within his local area code
For this example, program call bar group 1 as follows:
The "0" entered in memory slot 01 means:
•
All call numbers which subs. 11 dials and which begin with "0" are barred. These
are call numbers outside your own local area code, including of course all numbers
in other countries.
