10.10.2. Realization 
There are two kinds of tables:
- DDI table: table for checking the called (DDI) number (1 table)
- CLI tables: tables for checking the calling (CLI) number (19 tables)
INFO:
If checking CLI only and not called/DDI as well, then only 1 CLI table
can be used (CLI table #1)
For both kind of tables number patterns can be specified:
- the digits 0-9,
- the letter "X" indicating any digit 0-9,
- the letter "Z" indicating any number of any digits 0-9.
IMPORTANT:
The maximum number of entries over all of these tables
is 64000.
