What does T1 (payload) measure?

T1 (payload) measures the usable user-data throughput of a North American T1 digital carrier, equating to 24 channels at 64 kb/s each, totaling 1.536 Mbps excluding overhead.

How is T3 (payload) defined?

T3 (payload) represents the user-data throughput available on a T3/DS3 digital circuit after removing framing, signaling, and protocol overhead from its nominal 44.736 Mbps line rate.

Why convert from T1 to T3 payload data rates?

Converting helps compare bandwidth capacities between lower-rate T1 circuits and higher-capacity T3 circuits, useful for network upgrades, capacity planning, and integration of diverse systems.
