PBX Call Restriction
Code Restriction programming lets you enable/disable PBX Call Restriction and enter PBX
access codes. You only need to do this if your system is behind a PBX and you have trunks
programmed for behind PBX operation. Refer to
for the specifics.
Additional Default Entries For Common Permit Code Table
Additional entries have been added to the default Common Permit Code Table. The default
setting is as follows:
Table 1: 000
Table 2: 1800
Table 3: 1888
Tie Line Code Restriction Enhanced
In Program 34-01-05: E&M Tie Line Basic Setup – System Code Restriction, if this option is
set to 0, the system follows the setting in Program 21-05-13: Code Restriction Class –
Restriction of Tie Line Calls to determine whether or not the Code restriction setting in
Program 34-08 is to be followed. If this option is set to 1, the system follows the system Code
restriction settings defined in Program 21-05-01 through Program 21-05-13.
A user can temporarily override a extension Code Restrictions.
The system allows or denies outgoing access to trunks depending on Code Restriction.
If the system detects the call is answered by detecting reversal in an analog trunk this
restores both – way voice paths immediately.
When using DISA or Tie Lines, additional programming is required for Code Restriction
(DISA, refer to Program 25-10; Tie Lines, refer to Program 34-04).
A user can temporarily block their extension Code Restriction access, preventing unwanted
calls from being placed on their telephone while they are away from their desk.
Each phone and trunk have a Restriction Class. The higher class applies for outgoing calls.
For example:
When trunk class is 01 and station class 02, Toll Restriction Class 02 is applied.
When trunk class is 15 and station class 03, Toll Restriction Class 15 is applied.
