6. 4. 2 Digit barring
Digit barring facilities are user-definable filters used for regulating exchange access
authorization based on the numbers dialled. Several digit barring facilities are available
in each case for internal and outgoing traffic (internal and external digit barring facilities
( =cg)).
Difference between Internal and external Digit Barring:
• Internal digit barring filters internal phone numbers:
Numbers that are entered in the internal numbering plan.
• External digit barring filters external phone numbers:
Numbers that are sent into the network.
Allocating Digit Barring:
• Each user can be allocated internal and external digit barring for all three switch po-
sitions of switch group 1.
