Ericsson BusinessPhone: the TCD table - who can call whom (call restriction by number)

Practice



In the web management console:

1) Open System -> System Facilities -> TCD Table

2) Here you'll find a table where the X axis lists the TCD groups, and the rows are a set of rules. Each rule consists of a starting and ending number, or the first part of a number.

Here's an example of such a table:

: From To 1 2 3 4 5 6 7 8
0: 00 04 + + + + + + + +
1: 8000 8999 + + + +
2: 2000 3999 + + + + + +
3: 1000 1999 + + + + +

In this example:
a) Any TCD group can call emergency numbers;
b) Only groups 1, 2, 3 and 4 can call long-distance and mobile numbers
c) Only groups 1, 2, 3, 4, 5 and 6 can call local (city) numbers. As you can see, local numbers in this case are numbers whose first 4 digits fall within the range 2000-3999. For example, 200-10-10 is a local number. 355-05-05 is a local number and also falls under this rule
