Microprocessor Based Exchange Data Collection and Analysis Terminal Application to A.E.A. PABX

摘要

The traffic data acquisition and analysis comprises micro-processer based data collection, terminals (MBDCT) and a centralized computer. The MBDCT's can communicate with the computer through a data set system. Each (MBDCT) remote terminal is connected to about two hundreds subscriber lines. It scans the trunk lines to detect the on/off hook states and to calculate the call time and the called number. If the called subscriber is not from the 200 local lines, its status should be detected though the computer communication with the two terminals. The data collected by the terminal can be slightly analyzed using the microprocessor programming capability. Moreover, short quality performance reports can be printed on a printer interfaced to the microprocessor. Also, data can be transmitted to the central computer for further data traffic investigation. The analysis outcome can be utilized for telephone line maintenance and reorganization. This report is concerned with the terminal details as applied to the A-E-A. PABX. It consists mainly of five external lines and about 300 internal lines. (Atomindex citation 12:622619)
