8-Digit Matching Table Assignment
(Memory Block 1-1-60)
This Memory Block assigns the 8-Digit Matching Tables. Each
8-Digit Matching Table can have sixteen 8-digit entries. To cover
the many possible combinations (without listing each individual
number), code restriction letters can be used in place of digits.
The code restriction letters used and their numerical values are
as follows:
X = 0~9, , and
#
P = 0 and 1
N = 2~9
When 1X is entered in a table, and the table is assigned as a
day table in the 8-Digit Matching Table to Class Assignment,
any 1 + any digit call is denied if the table is used. Using X, P,
and N accommodates several combinations with just one entry.
N
The Trunk Access Code should not be placed in
the 8-Digit Matching Table. Code Restriction
starts after a trunk is seized.
8-Digit Matching Table to Class Assignment
(Memory Block 1-1-61)
This Memory Block assigns the 8-Digit Matching Tables to the
Code Restriction Classes. The 8-Digit Matching Tables are also
assigned as Allow/Deny Tables in this Memory Block. Any
combination of 8-Digit Matching Tables (Allow, Deny, or Not
Used) can be assigned to Code Restriction Classes 01~14.
Classes 00 and 15 are fixed and are non programmable.
Code Restriction Class Allow/Deny Selection
(Memory Block 1-1-65)
This Memory Block assigns the Code Restriction Classes
(01~14) as Allow or Deny. This assignment is used when there
is no match or when there is an overlap (duplicate numbers in
tables with opposite Allow/Deny assignments) of number in the
8-Digit Matching Tables.
8-Digit Matching Table Operations
The 8-Digit Matching Tables are used to restrict specific or all
OCC calls and non-OCC calls. To understand the relationship
of the 8-Digit Matching Tables with OCC calls, refer to
OCC Assignment/Operation on page 529
When a restricted station user makes a non-OCC call, the
system monitors the first eight digits dialled and searches the 8-
Digit Matching Tales assigned for Used in Memory Block 1-1-66
(8-Digit Matching Table to Normal Dial Assignment).
The system searches only the 8-Digit Matching Tables assigned
to the Code Restriction Class the station is assigned to and
has the Trunk group assigned to it for the in-use trunk the
station is on.
