Bandwidth allocation during upstream transmission is crucial to determine the efficiency and performance of a XG-PON. For XG-PON, bandwidth assignment is done based on T-CONT which represents a traffic class as per ITU recommendation. DBA scheme used in this paper is based on CBU to assign bandwidth to ONUs based on the T-CONT supporting QoS as per SLA. In this paper, CATV traffic is used as traffic generator which used for generation of Ethernet frames and results showed expected trend of mean upstream delay for traffic class T2, T3 and T4 as compared to recommended value which is below 1.5ms. These results prove that CBU can also be implemented on real time traffic.

The Outcome-based Education (OBE) implementations in the higher learning institution have been significantly affected by the Covid-19 outbreak, but its progression from pandemic to endemic signals better health regulations and controls. This paper aims to examine the relationship between course Program Outcome (PO) attainment and students' perception of the basic communication engineering (ECM241) course. The utilized methods are PO measurement through assessments and final examination as well as a student's satisfaction survey. The analysis is done for three different delivery modes: face-to-face, hybrid, and online delivery. Through the PO measurement, the results show that students mostly preferred the hybrid delivery mode due to the flexibility in its assessment and activities conducted, reduced facility usage, and time constraints for the course completion. The survey method also showed that most of the students are satisfied with the course content and all factors contributing to the course delivery. In conclusion, this subject is suitable to be conducted using the hybrid mode as compared to the conventional method. In the future, this research could be expanded by considering all subjects in the semester to access overall OBE achievement and students' satisfaction with the Electrical Engineering program.
