If two 256-QAM channels each provide a throughput of 38 megabits per second (Mbps) are bonded, what is the expected downstream throughput?

When two 256-QAM channels are bonded, their throughputs are combined to yield the expected downstream throughput. Each channel offers a throughput of 38 Mbps. When bonded, the total throughput can be calculated by simply adding the throughputs of the individual channels together. The calculation is straightforward: 38 Mbps (from the first channel) + 38 Mbps (from the second channel) = 76 Mbps. This total reflects the combined capacity when both channels are utilized simultaneously, therefore allowing for a higher data transmission rate. Thus, the expected downstream throughput, when bonding two channels of 38 Mbps each, is 76 Mbps.
