164 Access Restrictions
Trunk Barring
Trunk Barring is at the top of the hierarchy for Access Restrictions.
Virtual Network Services
Any VNS call is subject to the same Class of Service restrictions as if the call
was performed on a TIE trunk, regardless of the type of Bearer trunk used.
Trunk Group Access Restrictions (TGARs) do not apply to VNS, and
therefore they never restrict a VNS call from being made.
Feature packaging
This feature is included in base system software.
