The following example describes how you might administer Tenant Partitioning in an office complex.

You assign tenant partition 1, the universal tenant, as the service provider. All other tenants can call, and be called by, the service provider.

You assign tenant partitions 2 through 15 to individual businesses in the complex. You maintain the system-default restrictions for these tenants. These restrictions specify that tenants cannot access the telephones, the trunk facilities, or the other Communication Manager endpoints that belong to other tenants.

You assign tenant partition 16 to the restaurant in the building complex. You give all tenants permission to call the restaurant. However, to prevent access to trunks and other facilities that belong to other tenants, you do not allow the restaurant to call the other tenants.

You assign tenant partition 17 to all the CO trunk groups. You give all tenants permission to call tenant 17.

You assign tenant partition 18 to a trunk group that tenants 3 and 7 want to share. You give tenants 3 and 7 access to this partition, and you deny all other tenants access to partition 18. To prevent toll fraud, you do not allow tenant 18 to place calls to tenant 18.

All tenants can use the same Automatic Route Selection (ARS) route pattern. In this example, the trunk for tenant partition 18, the private trunk that tenants 3 and 7 share, is first in the route pattern. Tenant partition 17 is second in the route pattern. The system routes calls that tenants 3 and 7 make to partition 18 and then, as a second option, to partition 17. The system routes all other tenants directly to partition 17, because you deny all other tenants access to partition 18.

Assign the facilities that the tenants do not share to the tenant partition that the facilities serve. These facilities can include trunk groups, VDNs, telephones, attendant consoles, and other endpoints.

The table summarizes the calling permissions for the different tenant partitions. Yes indicates that the partitions have permission to call, and be called by, each other. No indicates that partitions cannot call, or be called by, each other.
