DCS
COMBINED PROGRAMMING MANUAL
Toll Restriction (Call Barring)
The system allows each station to be assigned a class of service (COS) for day and night
modes. 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 Allowance
Table).
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; and
levels B to G are programmable. In addition, the Wild Card Table (MMC 704) can be used to
provide 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 "no
restriction".
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 Table

Example
Let'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 International
numbers and 01 STD numbers. You would set up the Deny Table as follows:
ENTRY
001
002
003
004
005
006
Note: 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.
