Telephone network switches and other network elements are connected to the inputs of respective storage and verification elements (SAVE) which are a distinct improvement over prior art adjunct processors. The SAVE cooperates with a network information concentrator so as to provide raw data that is filtered of extraneous data so as to be useful as raw (filtered) data for downstream clients. The network information architecture described herein also operates upon input network event data to achieve event matching and database enhancement of the network event data. The end result is matched or enhanced data for downstream clients, when required. The network information architecture further cooperates with a generalized statistics engine for summarizing network event statistics or preselected types of calls, such as 800 or 900 number calls. These statistics become available, when desired, for downstream clients. The generalized statistics engine also provides alarm data, derived from statistics, for downstream clients.

A telephone network has elements that generate application data field (ADF) requests to data access points, requesting routing information for telephone calls. The data access points respond with application data field (ADF) records. A request and responding record constitute an ADF message pair. Call detail records are also generated by network elements during a call. A centralizing storage and verification system (SAVE) replaces prior art adjunct processors. It includes a network data buffer followed by a formatter for the network data that formats the data blocks and identifies them by corresponding sequence numbers. A buffer is provided for the blocked data and corresponding sequence numbers. An archiving hard disk is present for storing the network data blocks and corresponding sequence numbers. An interface expedites bi-directional data communication between the SAVE and an external information concentrator. A first input of the interface is connected to an output of the network data buffer for transferring network data to the concentrator. A second input of the interface is connected to an output of the hard disk for retrieving network data when previous communication of such data to the information concentrator is incomplete, and retransmission is requested by the concentrator. Verification is made of the requested data for retransmission, thus connecting only verified retransmitted network data to the interface for retransmission to the information concentrator.
