What does OC3 represent in data transfer?

OC3 stands for Optical Carrier level 3, carrying data at 155.52 megabits per second used in synchronous optical networking for backbone fiber transport.

What is a Virtual Tributary 2 (signal)?

Virtual Tributary 2 is a SONET/SDH sub-rate signal that carries a 2.048 Mbps payload, typically an E1 channel, within higher-rate SONET or SDH frames.

Why convert OC3 to Virtual Tributary 2 signals?

This conversion helps understand how many lower-rate E1 channels can be multiplexed inside a higher-rate SONET backbone, aiding in network design and resource management.
