Bypassing the digit barring
Digit barring facilities are bypassed in the following cases:
• Deactivation of the external digit barring allocated to the subscriber in the
route configuration
Example:
The digit barring is deactivated in the route configuration for route 1 and acti-
vated in the route configuration for route 2.
If a subscriber with an allocated external digit barring sets up a call via route 1,
the digit barring will not be consulted; if he sets up the call via route 2, the digit
barring will be consulted.
• Calls via analogue network interfaces set on "down-circuit from the PBX"
• Stored phone numbers of PISN subscribers
• Stored phone numbers of emergency and abbreviated dialling numbers, pro-
vided the emergency or abbreviated dialling number is dialled
• Stored phone numbers of abbreviated dialling numbers, provided they are
dialled using dialling-by-name
Note:
The digit barring for external remote control cannot be bypassed.
Setting up the digit barring
In a digit barring everything can in principle be enabled ("Basic function = enable
all") or barred ("Basic function = bar all").
Exceptions to the basic setup are entered in an enabled list or in a barring list.
Digit sequences that are not on the enabled or barring list are either enabled or
barred, depending on the basic setup.
A phone number is compared from left to right with the digit sequence of the
allocated digit barring.
