Final answer:
When sending DSL over a far distance, the signal strength decreases, signal quality decreases, and latency increases.
Step-by-step explanation:
When we are sending DSL over a far distance, the signal strength decreases due to the attenuation of the signal. This means that the signal becomes weaker as it travels along the line, resulting in a decrease in the quality of the signal. Additionally, latency, which refers to the delay in transmission, increases as the signal has to travel a longer distance.
