Maggy J I apologose for my reply which I posted after your post, can you please if possible move posts relating to ATDMA and SCDMA to this thread?

As I think was a good discussion, thanks.

I feel happy knowing that taxpayers are the ones footing the bill for this dolts escapades through VM's complicated billing system.

I look forward to him moving up to the 1.5gb business trials!

He would have to change his name to londoncable and go to one of the London businesses in trial for that to happen :p:

Sorry but that would be a little too complicated to do and that thread would not flow correctly.

Don't know about the flow of the thread Maggy as ATDMA and SCDMA are already mentioned and are both part of the DOCSIS 2 platform which the thread is about.

I can see the problem moving individual posts to it though.:D

I linked to this thread from the other so we can discuss the SCDMA stuff there now.

SCDMA is less efficient than ATDMA. 128QAM requires an insane upstream SNR, 64QAM is a challenge for operators to push to let alone another 3dB to cater to 128QAM and after overheads it doesn't actually provide anything more than 64QAM ATDMA.

SCDMA does indeed have a purpose, it is more resilient in the presence of burst noise that ATDMA, however horses for courses. If it were so evidently superior everyone would be doing it. They aren't.

Could you please take such discussions to this thread to prevent it being taken any further off topic.Thank you.

Tech Guy is booked for this thursday to check my power levels correctly. I had spoken to tech support and they had check my VMNG300 power level signal and say it need to be booked again for tech guy.

I clearly don't understand tax/business law, how or rather, why would the government foot the bill for someone's inability to decide on a product?

Either he got a load of tax rebate or is some sort of benefit income hence him saying government money.

With the poor English I'm guessing he is some sort of bod from abroad looking to test out our countries tiers of cable.
