ABSTRACT:
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.
