Toll Restriction

Default Toll Restriction
The system defaults two toll restriction tables with pre-programmed values and
pre-assigned to all lines. The programmer needs only to assign these tables to the stations
by programming action to put them into effect. He or she can use the toll restriction table
configuration class of service programming to reprogram the defaulted tables with
different information as needed.
Flexible Toll Restriction
A system programmer can configure system toll call restriction to prohibit some or all
stations from calling a wide range of number combinations. The restricted numbers are
specified on up to 16 tables. The system assigns several broad-range values to two of
these tables, and assigns the tables to all lines as a default condition. The programmer
needs only to enable the default tables on a per station basis to activate the default toll
restriction.
In general, toll restriction works as follows:
The programmable tables of restricted numbers can contain up to four entries and each
entry can contain up to 16 digits.
A programmer programs each table of restricted numbers to be an "allow" table or a
"deny" table with entries in an "allow" table overriding entries in a "deny" table. This
arrangement allows the programmer to enable exceptions to toll restriction. For example,
he or she can arrange the table entries so that the system allows the dialing of
1-800-xxx-xxxx numbers even though it denies the dialing of all 1-xxx-xxx-xxxx
numbers. A programmer can store a "match anything" symbol (#) to represent any digit
from 0 to 9 in the individual entries thus providing him or her with a broad range of
number combinations to choose from.
The programmer can individually assign the programmed toll restriction tables to each
appropriate station and line. Therefore, when an outside call is dialed, the system
examines the dialed number and makes a comparison between it and the toll restriction
tables. Any tables that the programmer assigned to BOTH the station being used and the
selected line determine the restrictions to be imposed. It should be noted that the system
will automatically disconnect a line from a station if its user dials a restricted number on
a restricted line from a restricted station.
Night Mode Toll Restriction
A programmer can assign toll restriction tables to any or all stations in the system that
will only take effect when the system is in the night transfer (of ringing) mode. These toll
