What does T1 (payload) represent?

T1 (payload) is the usable user-data throughput of a North American T1 digital carrier, totaling 1.536 Mbps without overhead.

How is T1C (signal) different from T1 (payload)?

T1C (signal) includes the entire T1 digital carrier signal rate of 1.544 Mbps, incorporating overhead and framing in addition to the payload.

Why convert from T1 (payload) to T1C (signal)?

Converting ensures bandwidth allocation matches the actual line rate including overhead, supporting accurate network design and planning.
