Nesting entries in the enabled and barred lists
Exceptions to a digit sequence barred in the barring list are entered in the enabled
list and vice versa. In the example on the left in Fig. 2.68 all phone numbers that
begin with the digit sequence "00" are barred except those that begin with
"003" or "004". This nesting depth is permitted.
The entry in the example on the right bars all phone numbers that begin with the
digit sequence "00" except those that begin with "003" but not with "0031".
This nesting depth is not admissible. The entry "0031" is ignored by the system.
