Great work dude. Thank you! Greetings from Greece

[yomama]

This video is very helpful thank you! I am learning copper splicing and there aren’t many resources to learn off the field

[Ressy]

Nice Trevor, hope you can do a video on vdsl2 w/vectoring
ps hope next video you are out of the submarine :)

[JuniorTaitt]

Great work, this was helpful! and 100% Bajan!

Thank you for your efforts so far, this is a nice video and well explained. However, starting from 25KHz to 28KHz is 3KHz instead of 4KHz, just a type I think.

You said the disparity in down and up speed is asynchronous - you should have said asymmetrical!

The amount of data carried "per slice" is not correct! As you go up in frequency you can "pack more in". An extreme example of this is an analogue TV link... You will never see a TV link on say SW frequencies for example. There is a whole stack of maths to support this. What is happening is higher frequencies don't travel as far. They "attenuate" more than the lower ones. Then its the noise that causes the drop off as mentioned.
