What does T1 (signal) represent?

T1 (signal) is a North American digital telecommunications standard transmitting data at 1.544 Mbps including framing bits and 24 multiplexed 64 kbps channels.

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

T1 (payload) designates the usable data rate, which is 1.536 Mbps, excluding the 8 kbps used for framing overhead in the T1 (signal).

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

Conversion helps determine usable data throughput and accurately specify bandwidth for voice channels, leased line internet, and trunk links.
