DPP system operation

Overview

The DPP allows data acquisition, storage, formatting, and forwarding from
the DMS-100. The DPP accepts billing data from the DMS-100 which
temporarily stores the collected data on hard disk. When requested, the
DPP retrieves, reformats, and sends the stored data to the HOC. Data
collected by the DPP includes call records for billing, statistics, and
maintenance. The data are stored in different files on disk drives for easy
retrieval controlled by the HOC located at the central collection point, as
shown in Figure 2-1. Figures 2-2, 2-3, and 2-4 show a block diagram of the
DPP and its interconnected systems on an information flow level.
