6 Grouping Polling Engines

In some cases it is desirable to be able to duplicate dialler account numbers

so that more than one dialler can use the same account number and yet each

can be uniquely identified by the IRIS System.

This could be, for example:

• For very large systems where the number of diallers installed is greater

than the number of account codes available.

• To support an existing estate of diallers where it is convenient to leave

the existing account numbers unchanged.

To support this facility, Polling Engines and diallers are assigned to a group.

Up to 256 groups are allowed.

A group of Polling Engines would typically include a Main and Backup (or two

load sharing units) and will be given unique IP addresses when installed. To

ensure that a dialler connects to the correct group, the IP address set into the

dialler on installation must be one of the Polling Engines of that group.

This is exactly analogous with traditional PSTN systems where different

groups of diallers are given different telephone numbers to dial.

An example is shown in the diagram below.

Group numbering is set up via the IRIS Console, both in the Polling Engine

configuration window and the Dialler Configuration window.
