Just as Tenant Number (TN) assignment determines the attendant group to which calls are terminated, the TN assignment also determines the VDN to which calls are redirected. If a VDN is administered, attendant group calls are redirected to the VDN rather than the attendant group. If a VDN is not assigned, calls terminate to the associated attendant group.

The selected TN for calls that are covered to an attendant group is the called user’s TN, not the calling user’s TN. When Tenant Partitioning is not administered, the system can have only one partition and attendant group. All attendant group calls are directed to attendant group 1. The screen to administer TN associations is not accessible, so system-wide console assignments apply. To follow the existing principals of this administration, the attendant vectoring VDN assignment appears on the Console Parameters screen when partitioning is turned off. When it is turned on, the field is removed from the console screen and the contents are automatically copied to TN 1.
