Subtitled:
Or How a Service Providing Internet Access Used ADSL2, Optical Fibre and VDSL2 Links in Series.As a diagram will definitely assist with the understanding, please equip yourself with an A4 sheet of paper and a pencil.
Orientate the paper in landscape mode and draw seven rectangles, equally spaced, in a line across the top of the paper. Within each individual rectangle insert one upper-case letter, from A to G, sequentially.
From the left-hand edge of the paper, draw a line to meet the mid-point of the left-hand side of rectangle A. Then draw lines linking the first six rectangles together. Do not draw a line linking rectangles F and G.
Now number the horizontal lines that are linking the rectangles. Between A & B, number it 1 . . . between E & F, number it 5. Finally, in the gap between F & G (there is no horizontal line), number it 6.
On the lower part of the A4 sheet of paper add the legend to the diagram:
