DEVELOPMENT OF A REMOTE-CONTROLLED BIT-ERROR-RATE TESTER SYSTEM FOR AVIAT NETWORKS

Abstract

Aviat Networks is a global provider of microwave networking solutions in public and private operators of communications networks. Its main product line is repairing and servicing microwave equipment outdoor units (ODU). The company follows 9 standard procedures in repairing, and soaking process is the focus of this study. Soaking process measures the unit’s reliability via Bit Error Rate (BER). The BER testing consumes 72 hours testing and requires physical monitoring by an in-charge engineer. Added to this, if power interruptions occur, the testing is discontinued and task will be repetitive causing a delay to its customers. This study aims to develop a remote-controlled Bit-Error-Tester System that is operational and accessible off-site, convenient, efficient, secured, monitors in real time, and configurable. The conduct of the study had made use of interviews, observations, surveys, experimentation and evaluation using ISO 9126. Software and hardware tools were used in configuring the network and interfacing hardware. Results show that the actual monitoring performance of BER testing on site as compared with the proposed BER testing off-site shows no significant difference, or the proposed remote control monitoring displays 98% efficiency in its performance. Furthermore, the adoptability of the system improved the soaking process by 30% during the period of testing and implementation. This implies an improvement in the soaking process and consequently provides lead time service to the company’s customers. It may be considered for future studies, the use of mobile phones for implementing the system.
