The Avaya IP Office Compact Business Center ( CBC ) is designed to provide a summary of both current and historical activity on an IP Office telephone system. It provides both overall system performance information and information on up to 3 selected hunt groups. Data is written every minute to a CSV file for each day. The CBC is able to access those files going back for 31 days.
The CBC obtains its call data from the IP Office via another application, the IP Office Delta Server. This can be on the same PC or on a separate PC. Each IP Office supports only a single Delta Server. However, the Delta Server is able to share that IP Office's call data with up to 80 simultaneous client applications. The schematic below shows the IP Office Delta Server and CBC on separate PC's.

This schematic shows the IP Office Delta Server and CBC on the same PC.

The CBC screen can display up to 4 charts. Each of these can plot up to 4 data variables for an agent group or the whole system, with each data variable being either real-time for the current day or historical for a selected day in the last 31 days.
