In order for toll restriction to take effect, the following three-fold process must occur.
Toll tables must be assigned to all appropriate lines.
l
Toll tables must be assigned to all appropriate stations.
l
Only the toll table(s) which are entered and assigned to both a line and a station using that line
will invoke any toll restriction.
TABLE ENTRY PROCEDURE
1. Determine the types of dialing restrictions which must be imposed on the system. Typically,
this includes access codes which result in toll charges, and certain local numbers as
desired.
2. If the restricted dialing codes will be imposed consistently on most or all stations in the
system, list them on one or two tables. If wide variation in the dialing restrictions is planned,
spread the listing out across several tables.
3 . Strategically group the listings on the tables so that a list of restrictions can be applied to a
particular station or group of stations.
4. Designate each table as a DENY table or as an ALLOW table. The numbers entered in a
DENY table are prevented from being dialed. ALLOW tables take precedence over DENY
tables. Therefore, an entry in an ALLOW table will provide an explicit exception to an entry in
a DENY table. Note that the system a/ways permits the dialing of any number not explicitly
denied. Also, system speed dial numbers will not be toll restricted unless specified by station
COS programming.
Example A:
Provide a simple and broad toll restriction format by creating a DENY table
l
with two entries: Entry (1) = 1 Entry (2) = 0. This format prevents all long distance and
operator calls.
Example B:
Prevent the dialing of all numbers within the (804) area code, while allowing
l
the dialing of one specific number within that area code, by entering 1804 in a DENY table
and 18049782200 in an ALLOW table. Alternately, allow all numbers in the 978 exchange
by entering 1804978 in an ALLOW table.
5 . Press the # key in place of a particular digit to condense a range of numbers into one entry.
table or an ALLOW table.
Example A:
If 357,377,387, and 397 dialing is to be prohibited, list one entry of 3#7 on a
l
DENY table to cover them all.
Example B:
Since area codes typically have a 1 or a 0 as a middle digit, prevent long
l
distance calls to those area codes by entering 1 #l# and 1#0# in a DENY table.
6. Since it is important that emergency numbers never be restricted, always create an ALLOW
table with entries of 911 and 1911 to override any DENY tables that have been created.
7 . If the system is installed behind a PBX, include an access code as part of every table entry.
8 . Once these tables are completely filled out, enter the restriction planning tables on the line,
and station programming reference charts to record the planned toll restrictions for the
system.
