Network ARS Programming with Line Pooling

When programming Automatic Route Selection on a networked system, follow these guidelines:

•

Program toll restriction for a specific extension from that extension’s node.

For example: If you want to prevent node #1, extension 334 from making long distance calls, apply the

restriction in the Toll/ARS programming of node #1.

•

All extensions that have their calls processed on a separate node are dependent on the remote COS.

For example: Node #1, extension 334 is dialing a local number which will use a line on the hub. The

remote class of service programmed for this extension under Stations/Station Programming/General is

the class of service the system uses to determine the appropriate restrictions and class of service on the hub.

If extension 334 has Remote COS 22 assigned to it, and COS 22 in the hub has a restriction level of 1, with

no lines programmed in the Originated On Lines menu, then the system prevents extension 334 from

dialing out. The reverse is also true if hub extensions are dialing out on the node’s lines.

•

You should assign each network card its own line group.

For example: If hub has 2 networking cards in it, assign each card its own line group. Verify each one of

these network line groups has the networking box checked under Lines/Line Group Programming.

•

All digits need to be buffered; please follow the example of the default Toll/ARS table on the next page.

•

Always program the Modify Digits table at the system where the calls access the service provider.

For example: Node extension 334 dials a local telephone number. The system routes the outbound call

through the hub; therefore, it is the hub, not the node, that will add or delete digits as necessary before

releasing the number to the service provider.

•

Assign toll group 1 to all lines for which you are programming Toll/ARS, whether they be on the hub or

one of the nodes.

In the example on the next four pages, all nodes have their own lines for local 7-digit dialing. The system will

route all “0” and “1+” calls over the PRI located at the hub, along with any local calling overflow. This example

will not be exact to your application, however, it should help you to understand how the pooling feature works in

both simple and complex environments.
