14.3 Filling the Call-Barring Allow and Disallow Tables
The system can store up to three call-barring Allow Tables and three Disallow Tables. Each table has 10 slots
(numbered 0 through 9). Each slot stores one phone number or prefix. (See the sample tables in Sections
14.4
and 14.5.
You must program all 10 slots for the table to work. If a slot is to be left empty, you must still program it as
an “empty” slot by simply hanging up, as described below. You can clear all slots of all tables by following the
instructions in Section 15.1.
To fill a Call-Barring Allow or Disallow Table:
1. In the programming mode, enter the code for the desired table:
720 Allow Table #1
721 Allow Table #2
722 Allow Table #3
723 Disallow Table #1
724 Disallow Table #2
725 Disallow Table #3
2. Enter the number (0 through 9) of the slot you want to program.
3. Enter the phone number or prefix you are putting in that slot (maximum of 12 digits).
If the slot is to be left empty, hang up.
4. Hang up. You must hang up after each slot for the programming to register.
