What is the data rate of a T1 (signal)?

T1 (signal) has a data rate of 1.544 Mbps, using 24 multiplexed DS0 channels at 64 kbps each plus framing over copper or similar media.

What does OC3 represent in data communication?

OC3 is a SONET optical transmission rate of 155.52 Mbps used for long-distance and backbone fiber transport carrying aggregated lower-rate channels.

Why convert from T1 to OC3?

Converting helps in network planning and managing upgrades from legacy T1 copper lines to higher-capacity OC3 fiber-optic circuits.

Does the conversion consider actual usable bandwidth?

No, the conversion uses ideal standard rates and does not include bandwidth reductions from framing or line conditions.
