AAR and ARS partitioning 

Issue 1

April 2000

You can use Automatic Alternate Routing (AAR) and Automatic Route Selection 
(ARS) partitioning to change the call routing plan for up to 8 different user groups 
within a single DEFINITY ECS. 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 
(PGN) 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. A similar call placed by an employee routes 
over a direct-distance dialing (DDD) trunk.

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

Use partitioning for:

■

groups with different routing due to special billing needs

■

groups that have dedicated use of a particular network facility

■

groups in different businesses serviced by a single system

■

data users who require special facility types on outgoing calls
