What does modem (28.8k) represent?

It is an informal label for a data-transfer rate of approximately 28,800 bits per second, indicating how fast data transmits over a dial-up modem connection.

What is meant by T3 (payload) in this context?

T3 (payload) refers to the user-data throughput portion of a T3 line after overhead used in digital telecommunications circuits.

Why convert from modem (28.8k) to T3 (payload)?

To compare legacy analog modem speeds with modern high-capacity digital lines for network planning and performance benchmarking.
