| Abstract | The monitoring system of transmission facilities is an essential support to ensure network reliability and is also an indispensable tool for maintenance. For other making of equipment, the monitoring system would only be able to collect alarming information but is not in a position to analyse faulty conditions for transmission quality control. To telecommunication networks, however, such a capability of qualitative analysis is just the most important performance that is desired. |
