DCS SPECIAL APPLICATIONSCOMBINED PROGRAMMING MANUAL NOVEMBER 20013–6Toll Restriction (Call Barring)OverviewThe system allows each station to be assigned a class of service (COS) for day and nightmodes. Into this COS is brought the dialling restrictions to be applied to each station. Dial-ling restrictions are applied in MMC 702 (Toll Deny Table) and MMC 703 (Toll AllowanceTable).Eight levels of restriction are available to stations: A, B, C, D, E, F, G and H. Level A im-poses no restrictions on station dialling; level H restricts stations to internal calls only; andlevels B to G are programmable. In addition, the Wild Card Table (MMC 704) can be used toprovide more flexibility when programming.Toll Restriction Rules• The Deny Table entries prevent certain numbers being dialled.• The Allowance Table entries are the ONLY exceptions to the Deny Table entries.• Listing codes in the Allowance Table with no entries in the Deny Table gives “norestriction”.• A wild card in any position in the Deny Table means an exception exists in the Al-lowance Table for the digits defined by the wild card.• A wild card at the end of an entry means that more digits may be dialled.• Never put a single wild card as an entry in the Allowance Table.• When changing an entry in the BCDEFG status, ALL digits must be entered.Use of Deny TableExampleLet’s assume that you want to restrict (bar) the dialling of the following codes to your users:0860 and 0850 car phone numbers, 0891and 0898 premium rate numbers, 00 Internationalnumbers and 01 STD numbers. You would set up the Deny Table as follows:TOLL DENY TABLEENTRY DIGITS B C D E F G001 0860 1 0 0 0 0 0002 0850 1 0 0 0 0 0003 0891 1 1 1 1 0 0004 0898 1 1 1 1 0 0005 00 1 1 0 0 0 0006 01 1 0 0 1 0 0Note: The number of entries allowed varies between systems (see MMC 702).From the above table (“1” means a number is barred):• Stations with Toll Level B applied will be barred all the codes listed.• Stations with Toll Level C applied will be barred 0891, 0898 and 00 calls.• Stations with Toll Level D applied will be barred 0891 and 0898 calls.• Stations with Toll Level E applied will be barred 0891, 0898 and 01 calls.
