You can use AAR and ARS partitioning to change the call routing plan for up to eight different user groups on a single server that is running Communication Manager. You assign a Partition Group Number (PGN) to each user group and identify different call routing treatment for each PGN.

For example, you can partition hotel employees and guests into separate groups and route the calls differently. When a guest makes a long distance call, the guest’s PGN and digit analysis tables route the call to a telephone billing system that allocates long distance charges. The system routes a similar call placed by an employee over a DDD trunk.

Partition user groups are used only with AAR, ARS, and UDP. You can assign AAR and ARS partitioning to telephones, attendant consoles, remote-access users, data endpoints, and incoming trunks.

Use partitioning for:

• Groups that have different routing because of special billing needs

• Groups that have dedicated use of a particular network facility

• Groups in different businesses that are serviced by a single system

• Data users who require special facility types on outgoing calls

You can assign a route pattern to just one partitioned user group, or you can assign a route pattern to all partitioned user groups.
