Operations control

摘要

Callers from telephone terminals (T1-Tn) of a telephone facility (C) are prompted by automated voice response (30) to transmit digital-signal data to a central station (D). The data received at the central station (D) is stored and analyzed (28) to identify subsets of the callers. The callers are qualified to use the system by consumable keys that are tested (23) within the central station (D), and call sequence and identification data are used within the station (D) to confirm caller-identity. The digital data received is identified for positive association with the caller and is stored in individual memory files or cells (C1-Cn) for processing (32). <IMAGE>
